The Sea to Summit Aeros Premium is the backpacker's answer to the question 'why do I sleep worse in a tent?' It weighs 3.7 ounces, packs down to roughly the size of a fist, and still manages to put a layer of memory foam between your head and the air chamber.
We researched it against the NEMO Fillo on comfort construction, packed size, and owner reports from long-distance hikers. The Aeros Premium is the ultralight pick of the two.

Comfort construction
Pure inflatable pillows feel like sleeping on a balloon. The Aeros Premium fixes that with a memory foam top layer under a brushed stretch-knit face, so the surface feels like fabric and has some give before you hit the air chamber. The scalloped shape cradles your head and is cut to fit inside sleeping bag hoods.
Weight and packability
At 3.7 ounces and a 4×3×3-inch packed size, it disappears into a pack lid pocket. That's the entire point: this is a pillow you bring on trips where your old solution was a stuff sack full of clothes. Backpackers report it inflates in a few breaths through the low-profile valve and deflates in seconds.
The PillowLock system
Inflatable pillows skate off sleeping pads at 3 a.m. — it's the category's most common complaint. Sea to Summit includes adhesive PillowLock patches that stick to your mat and grip the pillow's base fabric. Owner reports say it genuinely works, which matters more than any comfort spec.

How this review was researched
We have not slept on this pillow.

Final verdict
The Aeros Premium is the camping pillow for people who measure their gear in grams: astonishingly light and small, with just enough foam and knit to feel like a pillow instead of a pool toy. Car campers should get the plusher NEMO Fillo; everyone carrying their bed on their back should get this.
Mr. Squish score: 8.7/10
