In short
Good for
- Weight-first backpackers: at 55 g it is among the lightest shaped pillows
- Hooded mummy bags: the Regular fits inside the hood, with PillowLock patches for Sea to Summit mats
- Lightweight kits where every cm³ counts: it packs to about 0.23 L
Strengths
- 55 g and about 0.23 L packed, in the top band for both weight and size
- Mini valve inflates in a few breaths and lets you fine-tune the firmness
- Brushed recycled face fabric, 11 cm tall inflated, with a shaped base that centres it on the shoulders
- Maker says the current pillow has a hydrolysis-resistant polyether TPU laminate, an upgrade for damp conditions
Weaknesses
- No cushioning besides air, so it feels firmer than foam-topped pillows
- PillowLock only grips Sea to Summit mats
- A long-term owner of the older version found it uncomfortable for stomach sleeping
- No independent test of the current Regular was found, so comfort and durability are estimates, not reviewed scores
