Weight

From maker's figures 7/10

How much it adds to your pack. 7: Better than most.

Maker lists 99 g for the Regular, in the 70–119 g band. OutdoorGearLab weighed its sample at 96.4 g.

Packed size

From maker's figures 9/10

How much room it takes in your rucksack. 9: Among the best you can buy for this.

Maker gives a packed size of 11 cm long and 8 cm across: 3.1416 x 4 x 4 x 11 = 553 cm³, about 0.55 L, in the under 0.6 L band. OutdoorGearLab measured about 10 x 7.6 x 7.6 cm.

In short

Good for

  • Side sleepers who want a shaped, cushioned top on a pillow under 100 g
  • Hooded mummy bags: the Regular fits inside the hood, with PillowLock patches that stick it to a Sea to Summit mat
  • Three-season and winter backpacking where pack size and weight both count

Strengths

  • Weighs 99 g and packs to about 0.55 L, roughly the size of a small apple
  • New memory-foam layer under the stretch-knit cover cuts the bounce of a bare air pillow
  • Mini valve lets you let out a little air without deflating it
  • Curved edge supports the neck for side sleeping, 11 cm tall when inflated

Weaknesses

  • Narrow: OutdoorGearLab testers' heads rolled off it when they turned over
  • Still an air pillow, so firmer than foam pillows and can press on the ears when fully inflated
  • PillowLock only grips Sea to Summit mats; on other mats it can slide out of a hoodless bag
  • Hand-wash only, with no removable cover
  • No independent report yet on how this 2026 version holds up over time
