Buy the Sea to Summit Aeros Premium Regular, manufacturer model 1700435, ASIN B00HUL4KUI, when you want the inflatable camp pillow whose older card language prints about 13.4 by 9.4 by 4.3 inches, a weight near 2.8 ounces or 79 grams, a brushed 50D knit face, a TPU bladder, and a multi-function valve. Buy the Klymit Luxe Pillow XL, model 12LPGY01D, ASIN B01LTEDRVE, when you want the larger hybrid pillow whose card language puts the inflated footprint near 22 by 12.5 by 5 inches and the weight near 6.2 ounces, with a quilted cover and an air-plus-fill construction. Do not invent a price for either ASIN. The price moves.
Short version. A Nemo Fillo Blue Horizon and a Therm-a-Rest 14224 are the other pillow fight on this site. A Sea to Summit Ether Light XT ST81167 and a Klymit Static V 06SVGR02C are sleeping pads, not pillows. A Kelty 35413711RR and a Marmot 36310 are bags. A Hornet OSMO and a Tiger Wall TTWUL221 are tents. Darn Tough 1466 and Smartwool SW012900 are socks. This page is pillow 1700435 versus pillow 12LPGY01D.

| Job | Sea to Summit 1700435 | Klymit 12LPGY01D | Buy |
|---|---|---|---|
| What the card says you are holding | Aeros Premium Regular, model 1700435 | Luxe Pillow XL, model 12LPGY01D | Match the model cell before the brand pillow name. |
| Inflated size the language admits | About 13.4 x 9.4 x 4.3 inches on older card language | About 22 x 12.5 x 5 inches | XL is the larger footprint. Do not call them the same pillow. |
| Weight the language admits | About 2.8 oz / 79 g on older card language | About 6.2 oz | Ultralight packing is the Aeros split. Do not invent a third ounce. |
| Construction | Brushed 50D knit, TPU bladder, multi-function valve | Quilted cover, hybrid air plus fill | Air-only bladder is not hybrid fill. Read the cover sentence. |
| What this is not | Not the Ether Light pad, not every Aeros size | Not the Static V pad, not a stuff sack | Buy the pillow model on the card you opened. |
Who should buy the Aeros, and who should buy the Luxe XL?
Buy 1700435 if you want model 1700435, ASIN B00HUL4KUI, the Regular Aeros Premium whose older card language is the compact rectangle near 13.4 by 9.4 by 4.3 inches, the weight near 2.8 ounces or 79 grams, the brushed 50D knit, the TPU bladder, and the multi-function valve, and if you will pack a pillow that stays small when the pad and the bag already fill the sack. Buy 12LPGY01D if you want model 12LPGY01D, ASIN B01LTEDRVE, the Luxe Pillow XL whose language is the larger footprint near 22 by 12.5 by 5 inches, the weight near 6.2 ounces, the quilted cover, and the hybrid air-plus-fill feel, and if you will accept the ounce cost for the wider head landing.
Buy neither if you wanted a sleeping pad. The Ether Light and Static V page is that fight. Buy neither if you wanted the Nemo Fillo versus Therm-a-Rest pillow page. That is a different pair of ASINs. Buy neither if you needed a stuff-sack volume the pillow cards do not print as a liter number on this brief.
What is 1700435 actually for?
This card is a Sea to Summit Aeros Premium pillow in Regular, model 1700435, ASIN B00HUL4KUI. Older card language that travels with this part prints an inflated size near 13.4 inches by 9.4 inches by 4.3 inches and a weight near 2.8 ounces, also written as 79 grams. The face fabric language is a brushed 50D knit. The bladder language is TPU. The valve language is multi-function. Those cells are how this comparison will talk about the pillow. A later retailer table that reprints a different gram number for a different Aeros size is a different table. Do not average it into 1700435.
Regular is not Large. If the listing photograph shows a pillow that looks wider than the Regular footprint, match the model cell before you match the picture. The multi-function valve is the inflate and deflate story on the Aeros Premium language. It is not a claim that the pillow is a pump. You still blow it up. The brushed knit is the face that touches skin. It is not a quilted top like the Klymit Luxe cover sentence.
Two point eight ounces is the ultralight argument. It is not a reason to call the Klymit heavy in a way that invents a failed product. Six point two ounces is still a camp pillow weight. The split is packing priority, not morality. The TPU bladder is the airtight claim. It is not an IPX rating, and this card does not print a submersion test.
What is 12LPGY01D actually for?
This card is a Klymit Luxe Pillow XL, model 12LPGY01D, ASIN B01LTEDRVE. The size language that belongs to this comparison puts the inflated pillow near 22 inches by 12.5 inches by 5 inches. The weight language sits near 6.2 ounces. The cover language is quilted. The construction language is hybrid air plus fill. That hybrid sentence is the feel difference from a pure air bladder. Soft fill sits with the air chamber. It is not the same object as the Aeros TPU bladder under a knit face.
XL is in the model name. Do not order a non-XL Klymit pillow and call it 12LPGY01D because the brand matched. The Static V pad on the Ether Light comparison is a sleeping pad with a different model string. A pad is not a pillow. The quilted cover is what your cheek sees. Softness of the cover is not a printed loft number on this brief, so this page will not invent one.
Twenty-two inches of length is a different head and shoulder landing than thirteen inches of Aeros length. Side sleepers who want lateral real estate are shopping the Luxe footprint. Ultralight hikers who want the sack to stay tiny are shopping the Aeros Regular. Those jobs can both be honest without a price invented for either ASIN.
How do you use either pillow with the pad and bag pages?
A pillow sits on a pad. It is not a pad. The Ether Light XT ST81167 and the Klymit Static V 06SVGR02C are the pad fight. Do not put pillow ounces into a pad R-value argument. The Kelty and Marmot bags are the insulation fight. A pillow does not replace a bag rating. The Hornet and Tiger Wall tents are the shelter fight. A pillow does not guy out a vestibule.
The Nemo Fillo and Therm-a-Rest pillow page is the other pillow conversation. If you already know you want a compressible foam-style camp pillow from that fight, this Aeros versus Luxe XL page is a different geometry. Aeros Premium Regular is the small air pillow with the knit face. Luxe XL is the large hybrid. Fillo is neither of those cards.
Socks are not pillows. The Darn Tough and Smartwool page is linked because camp kits collect soft goods in the same sack. It is not a sizing guide for 1700435.
What actually fails on these two cards?
The Aeros card fails when Regular is shopped as Large because the photograph looked soft. It fails when 2.8 ounces is treated as every Aeros in the catalog. It fails when the multi-function valve is sold as a built-in pump. It fails when the TPU bladder is called waterproof clothing. It fails when the Ether Light pad is ordered because Sea to Summit matched and the model did not. It fails when a price is invented for B00HUL4KUI in a sentence that pretends to be a feature.
The Luxe XL card fails when 12LPGY01D is confused with the Static V pad model 06SVGR02C. It fails when 6.2 ounces is rounded down to the Aeros weight to win an ultralight argument. It fails when hybrid fill is described as a pure air pillow. It fails when 22 by 12.5 by 5 inches is pasted onto 1700435. It fails when a non-XL Klymit pillow is ordered because the gallery matched. It fails when a price is invented for B01LTEDRVE.
What is this comparison not?
This is not a sleeping pad comparison. This is not every Sea to Summit Aeros size and every Klymit pillow. 1700435 and 12LPGY01D are the cards. This is not the Nemo Fillo versus Therm-a-Rest pillow page. This is not a price quote. The price moves. Use the buttons if you want the live listing. This is not a tent review, a bag review, or a sock review. Those pages are linked above because that is where those objects live.
This is also not a claim that one pillow ends neck pain. Neither card prints a medical claim this page will repeat as advice. Softness is a feel. Measure the inflated footprint if your pad is narrow.
How do you pack either pillow without inventing a liter rating?
Neither brief for this page prints a stuff-sack volume in liters as a hard Amazon cell you must treat as gospel. Pack the Aeros Regular by rolling the deflated bladder toward the valve and pressing residual air out through the multi-function valve language. Pack the Luxe XL by the same air-out habit, then accept that the quilted hybrid cover still occupies more sack space than a 2.8-ounce air pillow. A compression sack that already holds a bag and a pad will feel the Luxe first. That is geometry, not a moral failure of model 12LPGY01D.
On a narrow pad, measure the inflated width before you assume the Luxe XL will sit centered all night. Twenty-two inches of pillow length can overhang a slim pad. The Aeros Regular's shorter rectangle is easier to keep on a narrow foam or air pad, which is why ultralight kits often keep the smaller footprint even when the cheek prefers more loft. Loft without a printed medical claim is still loft. This page will not diagnose a neck.
Wash language belongs on the care card you open with the listing. Do not invent a washing-machine cycle here. Spot clean what the manufacturer says you may spot clean. A TPU bladder that is punctured is a puncture. A hybrid fill that mats is a fill problem. Keep those failure modes apart when you decide which ounce budget you are buying.
Camp kits also collect a headlamp, a sack of socks, and a tent stake bag in the same tote. The Darn Tough and Smartwool page is soft goods. The Hornet and Tiger Wall page is shelter. Neither rewrites the pillow model cell. If you already own the Nemo Fillo from the other pillow fight, you are not required to own 1700435 as well. Two pillows in one kit is a choice, not a rule this comparison invents.
So which camp pillow should you buy?
Buy the Sea to Summit if you want model 1700435, ASIN B00HUL4KUI, the Aeros Premium Regular whose older card language is the compact size near 13.4 by 9.4 by 4.3 inches, the weight near 2.8 ounces or 79 grams, the brushed 50D knit, the TPU bladder, and the multi-function valve. Buy the Klymit if you want model 12LPGY01D, ASIN B01LTEDRVE, the Luxe Pillow XL near 22 by 12.5 by 5 inches and about 6.2 ounces, with the quilted cover and hybrid air-plus-fill construction. Buy neither if you wanted a pad, the Fillo fight, or a size the model cell does not name.
