In short
Good for

- Backpackers who want a down-topped pillow and can carry 175 g
- Sleepers on a Sea to Summit mat: PillowLock patches hold it in place
Strengths

- Packs to 16 x 7.5 cm, about 0.71 L
- Down-filled top softens the air chamber against the cheek and ear (CleverHiker)
- Mini valve lets you fine-tune the firmness and empty the pillow quickly
Weaknesses

- Down needs careful washing and drying (CleverHiker)
- Not enough evidence yet on comfort and long-term durability of this size
