In short
Good for
- Ultralight backpackers who want a bigger pillow for about 80 g
- Side sleepers and restless sleepers who find the Regular too small
- Packs where space is tight: it rolls to about 0.30 L
Strengths
- 80 g and about 0.30 L packed, in the top band for packed size
- Larger 45 x 31 cm top and 12 cm tall inflated, with a shaped base
- Mini valve inflates in a few breaths and lets you fine-tune the firmness
- PillowLock patches help it stay on Sea to Summit mats
Weaknesses
- Air only, with no foam, so it feels firmer than foam-topped pillows
- 25 g heavier than the Regular (55 g)
- PillowLock only grips Sea to Summit mats
- No independent test of the current Large was found, so comfort and durability are estimates, not reviewed scores
