Sea to Summit Aeros Down Backpacking and Camping Pillow

The Sea to Summit Aeros Down Pillow is a rectangular, ultralight pillow for backpackers and campers that combines a duck-down top layer with an adjustable air chamber for up to 12 cm of customizable thickness. The soft-touch 20D recycled nylon pillowcase and hydrolysis-resistant TPU air bladder keep packed weight to 77 g for the Regular and 97 g for the Large.

Down Comfort Without the Weight Penalty

A plush duck-down layer sits directly above the air chamber, so the surface that contacts your face and neck is quiet, soft, and warm rather than the crinkly feel of a bare inflatable. Because the air chamber does the structural work, the down fill can stay light (the Regular weighs just 70 g unpacked) without sacrificing the cushioned feel that makes sleep genuinely restorative after a long day on trail or at camp. Adjustable firmness means side sleepers and back sleepers can dial in support rather than accepting a fixed loft.

Fast Inflation, Precise Adjustment

The mini XPRESS valve integrates a one-way inflate port, a rapid-dump deflate port, and a fine-tune button in a single low-profile unit. Inflation, firmness adjustment, and full deflation each take seconds, with no separate valve cap to lose. The valve nozzle is sized to accept the Airstream Pump from a Sea to Summit air mat turned inside out, which speeds inflation further for anyone already carrying that pump.

Stays Put All Night

The included 3M PillowLock System patches use self-adhesive hook-and-loop material to anchor the pillow to most sleeping mats. The patches grip firmly enough to keep the pillow from sliding during sleep but will not snag lightweight sleeping bag fabrics. The 20D recycled nylon pillowcase fabric is the same soft lining used in the Sea to Summit Ascent sleeping bag, chosen for next-to-skin comfort rather than durability alone. The TPU air bladder uses a polyether laminate formulation that resists hydrolysis for long-term durability.

Specifications

Who This Is For and Isn't

The Aeros Down Pillow suits backpackers and campers who want the feel of a down pillow at ultralight packed weights, and anyone who has found bare inflatable pillows too noisy or slippery to sleep on comfortably. Both sizes work with the PillowLock System on compatible sleeping mats.

The Aeros Down Pillow is not machine washable: hand washing only, air dry, no dryer. The PillowLock patches adhere to most but not all sleeping mats. TerrainVault carries the Regular and Large sizes; the XL size is not currently available here.

Common Questions

Is the Aeros Down Pillow machine washable?

The Aeros Down Pillow is not machine washable. To clean it, close the valve, use warm water with a gentle kneading motion, and allow it to air dry completely. Do not put it in a dryer.

How difficult is it to inflate and deflate?

The Aeros Down Pillow inflates and deflates quickly using the mini XPRESS valve, which handles inflation, firmness adjustment, and full deflation without a separate cap. Anyone carrying a Sea to Summit air mat can turn the Airstream Pump inside out to use its nozzle with the mini XPRESS valve for faster inflation.

Will the pillow slip off a sleeping mat during the night?

The Aeros Down Pillow includes 3M PillowLock System patches that adhere to most sleeping mats and hold the pillow in place through the night. Sea to Summit sleeping mats produced since Spring 2019 ship with matching patches already attached.

How does the pillowcase fabric feel against skin?

The upper surface of the Aeros Down Pillow uses the same soft lining fabric found in the Sea to Summit Ascent sleeping bag, chosen specifically for next-to-skin comfort rather than a standard technical shell.
