Ether Light XT ST81167 vs Klymit 06SVGR02C

Buy the Sea to Summit Ether Light XT Extra-Thick Insulated pad, model ST81167, size Small, color Smoke, when you want the tapered air pad whose bullet says R-value 3.2, a 4-inch thickness, and a packed size of 4.5 by 9.5 inches. Buy the Klymit Static V, model 06SVGR02C, green, style Uninsulated, when you want the rectangular pad whose bullet says R-value 1.3, an inflated size of 72 by 23 by 2.5 inches, and a packed weight of 18.7 ounces. One card claims insulation. The other card’s style cell says it does not have it. Both are ranked with self-inflating mats, and both are air pads you blow up.

Short version. A NeoAir and a Tensor are the lighter insulated pair, not these two model numbers. A 35-gram lamp is what you wear on your head, not what you sleep on. A hammock replaces the pad only if you sleep off the ground. A bottle is the water, not the mattress. Match ST81167 or 06SVGR02C before you match the word sleeping pad.

The Sea to Summit detail ASIN is B085HCHXP1. The model cell says ST81167. The model-name cell says Amelxtinsts, which is a catalog token, not a name you will see on the stuff sack. The manufacturer-part cell says ST81167. The GTIN is 09327868131389. The color cell says Smoke. The size cell says Small. The dimensions cell says 66 x 21.5 x 4 inches. The weight cell says 16 ounces. A bullet says the pad packs to 4.5 by 9.5 inches, weighs 1 pound, and has an R-value of 3.2. Sixteen ounces and one pound are the same number, so those two lines agree. The 4-inch figure in the dimensions cell and the 4-inch bullet agree on thickness. The length and width are a tapered small, not a rectangle. A comparison module on the same page quotes “Weight of Tapered, Regular Size” at 1.1 pounds. That line is the regular size in the family, not this small. Do not paste 1.1 pounds onto ST81167.

The Sea to Summit bullets also name Air Sprung Cells, an Airstream pump sack, fiberfill and a reflective fabric, 30D/40D nylon, a stuff sack, a field repair kit, and PillowLock. PillowLock is a patch system for a pillow the card does not include as its own SKU. The included-components cell says “Components included in the description.” That is a shrug. The bullets are the packing list you actually have: pad, pump sack, stuff sack, repair kit. Count them. The construction cell says Single-layer Air Sprung Cell. The number-of-layers cell says 2. A single-layer construction cell and a two-layer count cannot both be a precise description of the stack. The comfort-layer material cell says Polyfoam. The fill cell says Fiberfill. Polyfoam and fiberfill are not the same word. The bullet’s “fiberfill and reflective fabric” is the insulation claim that supports the R-value 3.2 line. The polyfoam cell is the one to distrust until you cut the pad open, which you should not do. The firmness cell says Plush. The water-resistance cell says Waterproof. An air pad with a waterproof cell is still a pad you can puncture. Waterproof does not mean you can use it as a raft, and the card does not say it floats you. The rank is Self-Inflating Sleeping Mats. The bullet says you use a pump sack. A pump sack is not open-cell foam reinflating itself. The rank is wrong in the same way a lot of air-pad listings are wrong. Read the pump-sack bullet.

The warranty language on the Sea to Summit card is a lifetime materials warranty. Read the current card before you treat that as a promise about a torn baffle, because warranty cells and warranty paragraphs on this site often disagree. The card does not print a temperature rating in degrees. R-value 3.2 is the number it prints. It also says 3-season in the bullet. Three-season is not a degree. Do not convert 3.2 into a lowest air temperature and attribute the conversion to Sea to Summit. The card did not do that math for you.

The Klymit card’s detail ASIN is B07YP8MLNN. The style cell says Uninsulated. The color cell says Green. The model cell says 06SVGR02C. Two UPCs appear: 846647009873 and 846647006797. The GTIN is 00846647006797, which matches the second UPC with a leading zero. If a seller’s barcode is the other UPC, you are in the conflict the card already printed. The shape cell says Rectangular. The included-components cell names a sleeping pad, a stuff sack, and a patch. That is a real packing list, unlike the Sea to Summit shrug. The bullet labeled as tech specs says an inflated size of 72 by 23 by 2.5 inches, 10 to 15 breaths to inflate, a packed weight of 18.7 ounces, a packed size of 8 by 3 inches, 75D polyester, and an R-value of 1.3, also printed as ASTM 1.3. The style cell and the R-value agree that this is the uninsulated pad. An insulated Static V is a different model. Do not let a photo of an orange pad, or a title from a different ASIN, talk you into expecting insulation this card does not claim.

The Klymit thickness cells are a mess, and they are the reason to measure. The product-dimensions thickness cell says 2 inches. The item-thickness cell says 5 inches. The item-depth cell says 2.5. The item-dimensions cell says 72 x 23 x 2. The bullet says 2.5 inches thick. Two, two and a half, and five cannot be the same inflated height. The bullet and the depth cell are the pair that match. The 5-inch cell looks like a different pad’s number. The 2-inch cell looks like a rounded or wrong dimension block. Lay a tape on the inflated pad. The item-weight cell says 513 g. The packed-weight bullet says 18.7 ounces. Five hundred thirteen grams is about 18.1 ounces, which is close to 18.7 and not identical. Close is not the same cell. The card does not say whether 513 g includes the stuff sack. The capacity cell says 250 pounds. The firmness cell says Medium. The Sea to Summit firmness cell says Plush. Those words are not a lab scale. The water-resistance cell says water resistant, not waterproof. The number-of-layers cell says 1. The fill cell says Air. The comfort-layer cell says Polyfoam. An uninsulated pad whose fill is air and whose comfort layer says polyfoam is the same class of conflict as the Sea to Summit fiberfill-versus-polyfoam pair. Believe “uninsulated” and R-value 1.3 until a cutaway you will not make says otherwise. The rank is again self-inflating. The bullet says 10 to 15 breaths. Breaths are not a self-inflating foam pad. The warranty cell says limited lifetime. A newer-model banner, if it is still on the page when you open it, means this green 06SVGR02C may not be the pad Klymit is pushing this season. The model cell is still the thing you match.

Who should buy the Ether Light, and who should buy the Static V?

Buy ST81167 if you want the small tapered insulated pad, the 4-inch cell, and R-value 3.2, and if a 66-inch length is long enough for you. A small is not a regular. The 1.1-pound comparison line is the regular. If you need a longer pad, this ASIN is the wrong size even if the family name is right. Buy 06SVGR02C if you want the green uninsulated rectangular pad, you can live with R-value 1.3, and you will measure thickness because the card prints three. Buy the Klymit if the packed weight near 19 ounces and a 72-inch length matter more than the insulation the other card claims. Do not buy the Klymit expecting the Sea to Summit’s 4-inch plush cell. Do not buy the Sea to Summit expecting the Klymit’s 250-pound capacity cell, because ST81167 does not print that number.

Neither card is a winter pad by a degree rating you can quote. The Sea to Summit bullet says 3-season and 3.2. The Klymit says 1.3 and uninsulated. On cold ground the lower number is the one the card tells you to expect less from. Do not add a rumor about R-value 4 or 5 from a different Ether Light generation. This model cell is ST81167. A newer XR pad is a different product and a different video.

What the Ether Light XT ST81167 is actually for

This is a smoke-colored tapered small air pad with a pump sack and a repair kit in the bullets. The Air Sprung Cell line is the baffle shape. The card does not count the cells. The layers conflict, single versus two, sits unresolved. Use it under a sleeping bag on ground where R-value 3.2 is the number you planned around, not under a cot the card never mentions. The PillowLock bullet is for a pillow sold separately. The field repair kit is the part you should find in the sack before the trip, not after a leak. The stuff sack and the pump sack may be the same item or two items. The bullet lists both a stuff sack and an Airstream pump sack. If you unpack only one sack, the card over-counted or you missed a piece. Look twice.

Sixteen ounces in the weight cell includes whatever Amazon’s scale or the maker’s copy included. It matches the “1 pound” bullet. It does not match a family comparison that says 1.1 pounds for the regular. Pack weight is this small pad, not the regular. The 30D/40D nylon bullet is a fabric pair, floor and top, and the card does not say which face is 40D. Waterproof in the water-resistance cell will not save a seam split. Plush in the firmness cell is not a psi. The valve in the photo is the inflation point. The card does not print a valve name beyond the Airstream pump sack.

What the Klymit 06SVGR02C is actually for

This is a green rectangular uninsulated Static V. The V in the name matches the baffle shape in the photo, not a Roman numeral for a version you can prove from the model cell. The model cell is 06SVGR02C. The bullet’s 75D polyester is thicker fabric on paper than the Sea to Summit’s 30D/40D line. Thicker on a cell is not a durability test. The 10-to-15-breath line is the inflation method. If you need more breaths, you are not done, and the card is not a medical claim about lung volume. The patch in the included list is the repair, singular. The Sea to Summit bullet says a field repair kit. A kit and a patch are different amounts of parts. The 250-pound capacity is the load cell. It is not a promise about a sharp rock. The limited-lifetime warranty cell does not list the exclusions. Read them on the card you buy, not in a summary.

The two UPCs are the practical failure. Scan the bag. If the code is 846647009873, the card listed it. If it is 846647006797, the card listed that too. If it is a third code, stop and match 06SVGR02C in print. Green is the color cell. A blue or orange Static V on a different listing is not this ASIN even when the shape looks related. The GTIN with the leading zero is the machine-readable form of one of those UPCs, not a third product.

How to sleep on them without mixing the two pads

Inflate the Sea to Summit with the pump sack the bullet names. Do not treat the self-inflating rank as permission to unroll it and wait. Inflate the Klymit with breaths, 10 to 15 on the bullet, and stop before the baffle welds look tight and shiny. Neither card prints a maximum psi. Overfilling is how air pads fail, and the cards do not give you a gauge number. Use the repair piece before a trip as a dry run only if you can reseal the practice hole. Better: find the patch, confirm it is there, and leave it sealed. The Sea to Summit small is 66 inches long. If you are taller than that, your feet hang off, and the Klymit’s 72-inch bullet is the longer printed length. The Klymit is also wider on the printed numbers, 23 inches against 21.5. A wider uninsulated pad is still R-value 1.3.

Do not stack the cards’ R-values and call the pair a winter system. Two pads on top of each other are a different experiment, and R-values do not add on this page because nobody printed the sum. Do not put the Klymit under you on frozen ground because the Sea to Summit’s 3-season line was in the same article. The style cell on the pad you are lying on is the one that counts. Do not wash either pad in a machine. Neither card says you can. Dry the valve. A damp valve left closed is how the next inflation smells, and that is camp practice, not a cell.

What actually fails on these two cards

The Sea to Summit card fails when the regular-size 1.1-pound line is copied onto the small. It fails when the layers cell (2) and the construction cell (single-layer) are both quoted as the build. It fails when polyfoam and fiberfill are merged into one material. It fails when the self-inflating rank sends the pump sack to the bottom of the pack. It fails when PillowLock is read as a pillow in the box. The Klymit card fails when 5 inches, 2 inches, and 2.5 inches are averaged. It fails when 513 g and 18.7 ounces are treated as one confirmed pack weight without a note. It fails when an insulated colorway is ordered from a different ASIN because the word Static V matched. It fails when the two UPCs are assumed to be a typo instead of a conflict you can scan. It fails when “water resistant” is upgraded to the other pad’s “waterproof.”

Both cards fail if you shop the rank. Self-inflating is the wrong aisle for a pump-sack pad and a breath-inflated pad. Both cards fail if firmness words, Plush and Medium, are used as a pressure spec. Both warranties, lifetime materials and limited lifetime, fail you if you needed the exclusion list and did not open it. A capacity of 250 pounds is only printed on the Klymit. Do not lend that number to the Sea to Summit.

What this comparison is not

This is not a temperature test. No night in a tent was logged here. This is not the Ether Light XR, and the video attached below is an Ether Light XT comparison against an Alton pad, not a test of model ST81167’s small size and not a frame of the Klymit. This is not a NeoAir review. This is not a claim that 30D nylon is too light or that 75D is bombproof. The denier numbers are cells. This is not a price quote. This is not advice to buy a pad for a child from the choking lines on a fishing page. These are adult sleeping pads with the sizes printed above. A small tapered pad is a short adult or a smaller sleeper, and the card says Small, not youth.

So which pad should you buy?

Buy ST81167 if you want the smoke small tapered pad, 4 inches, R-value 3.2, a pump sack, and a 16-ounce cell, and if you will ignore the self-inflating rank and the regular-size weight in the comparison module. Buy 06SVGR02C if you want the green uninsulated rectangle, R-value 1.3, a 72-inch bullet, and a patch in the box, and if you will measure the height because the card cannot decide between 2, 2.5, and 5 inches. Buy the insulated pad when the ground is cold enough that 1.3 is the number you do not want. Buy the uninsulated pad when the printed R-value is enough and you want the longer rectangle. Match the model, then the size, then the style cell.

Kelders Outdoors’ film “Ultralight Sleeping Mat Comparison - Alton Insulated Mat vs Sea to Summit Etherlight XT” shows an Ether Light XT and an Alton pad. It does not show Klymit 06SVGR02C. It is not a measurement of the small ST81167 against the green Static V. Use it to see an Ether Light baffle and valve, not to import the Alton’s specs onto either ASIN.
