Hyperlite Mountain Gear Stuff Sack Pillow

The Stuff Sack Pillow is a dual-purpose accessory rather than a dedicated inflatable pillow: a Dyneema stuff sack with a Polartec fleece lining on one side, so it works as a waterproof storage sack during the day and, filled with spare clothing at camp, becomes a soft pillow at night. At 47.9 g it weighs a fraction of what a standalone inflatable or foam camp pillow costs in pack weight, since the pillow function is essentially free once you are already carrying a stuff sack and spare layers. The inflated-equivalent dimensions of roughly 43 x 30.5 cm give a reasonably generous surface for a filled sack, though comfort and firmness depend entirely on how much and what type of clothing is stuffed inside rather than a fixed baffle structure. This makes it inconsistent night to night compared with a purpose-built inflatable pillow, but it eliminates the need to carry a separate item at all. It suits ultralight backpackers optimising for multi-use gear and minimal base weight, less so hikers who want a consistently plush, dedicated pillow.
