The Sea to Summit Aeros Ultralight Pillow is a standout piece of gear for backpackers, bikepackers, and fastpackers who want real comfort without sacrificing weight or pack space. At just 60 grams and packing down smaller than a deck of cards, it’s one of the lightest and most compact inflatable pillows on the market. But unlike many ultralight options, it doesn’t feel like a balloon under your head. With smart design features and surprising support, it’s earned a loyal following among wild campers and long-distance trekkers.
Materials and Build Quality
The Aeros Ultralight Pillow is made from 20D laminated polyester, which strikes a balance between softness, durability, and weight. The fabric has a smooth, slightly grippy texture that helps keep the pillow in place on sleeping mats or inside sleeping bags. It’s not plush like fleece-covered pillows, but it’s comfortable against the skin and dries quickly if damp.
The internal structure features curved baffles that cradle the head and prevent the pillow from feeling overly inflated or unstable. This design helps distribute pressure evenly and keeps the pillow from shifting during the night. The seams are heat-welded and hold up well to repeated use, even when packed tightly or exposed to moisture.
The valve system is Sea to Summit’s multi-function mini valve, which allows for fast inflation, easy deflation, and micro-adjustments. It’s intuitive and low-profile, and unlike twist valves, it doesn’t protrude or catch on gear.
Weight and Packability
Weighing just 60g, the Aeros Ultralight is one of the lightest full-featured pillows available. It packs down to 5.5 x 7 cm, which is smaller than most energy bars and fits easily into a side pocket, cook kit, or dry bag. The included stuff sack is minimal but effective, and the pillow compresses flat without damaging the baffles or valve.
For ultralight setups, this pillow is a game-changer. It adds genuine comfort for a negligible weight penalty, making it ideal for thru-hikes, bikepacking trips, and minimalist wild camps.
Comfort and Sleep Experience
Despite its tiny size and weight, the Aeros Ultralight Pillow offers impressive comfort. The curved internal baffles create a contoured surface that supports the neck and head without feeling like a balloon. It’s especially effective for back sleepers, though side sleepers may want to pair it with a folded jacket or extra padding for height.
The pillow inflates in 2–3 breaths, and the valve allows for fine-tuning firmness. You can go from soft cradle to firm support in seconds, and the pillow holds air reliably throughout the night. There’s no crinkling noise, and the shape stays consistent even with movement.
For campers used to stuffing clothes into a dry bag or using rolled-up jackets, the Aeros Ultralight is a major upgrade. It feels like a real pillow, not a compromise.
Compatibility and Integration
The Aeros Ultralight is designed to lock into Sea to Summit sleeping mats via their Pillow Lock system. This uses small adhesive patches on the mat and a grippy surface on the pillow to prevent slippage. It’s optional but effective, especially on slick inflatable mats.
Even without the lock system, the pillow stays in place reasonably well thanks to its shape and fabric texture. It fits neatly inside mummy bags and works well with rectangular pads. For hammock camping, it’s light enough to suspend or wedge into a corner without issue.
Durability and Maintenance
The 20D polyester is thin but surprisingly tough. Users report years of use without punctures or leaks, provided the pillow is stored properly and kept away from sharp objects. The valve is robust and doesn’t clog or degrade with use.
Cleaning is simple—wipe with a damp cloth or rinse with mild soap. The pillow dries quickly and doesn’t retain odours. The stuff sack helps protect it from abrasion and UV exposure during transport.
Use Cases and Versatility
The Aeros Ultralight Pillow is ideal for:
- Thru-hiking and fastpacking: Minimal weight and maximum comfort.
- Bikepacking and cycle touring: Fits easily into frame bags or panniers.
- Wild camping and bivvying: Adds comfort without bulk.
- International travel: Works well on planes, trains, and buses.
- Emergency kits: Compact enough to stash in a grab bag.
It’s not designed for car camping or glamping, where larger, plush pillows may be preferred. But for lightweight adventures, it’s hard to beat.
