By using ultralight materials to construct a down cushion-top over a TPU air bladder, the Pillow Aeros Down Large from Sea to Summit is one of the lightest fully-featured down pillow on the market. Differentially cut horizontal baffles reduce down migration and prevent the down compressing, even when the air bladder is fully inflated. The cushion-top wraps over the front of the pillow for neck comfort. The rest of the pillow case is made from lightweight 20D fabric. Aeros™ bladder use a unique long-lasting anti-hydrolysis TPU film which prevents material breakdown from moisture exposure. Extremely light, the bladder’s horizontal baffles create a 3D surface that cradles the head for additional support. The multi-function mini-valve provides easy inflation, deflation and fine tuning.\n\nLength: 42 cmWidth: 28 cmHeight: 12 cmPacked dimensions: 9x7 cmPremium down cushion-top for comfort and warmthUltralight and high-strength TPU bladderDifferentially cut baffles allow maximum down loftTechnical fabrics for lightweight performanceMulti-function mini-valve for easy inflate, deflate and fine tuningStore and transport in compact 20D stuff sackFabric: 100% Nylon, Primary Filling Material: DUCK DOWN (Min. 85% Down), Bladder: 100% TPU Sea To Summit Aeros Down Pillow Large Grey | Buy Sea To Summit Aeros Down Pillow Large Grey here | Outnorth
