The Airstream Pump Sack features a low-profile valve that connects to the multi-function valve on all Sea to Summit sleeping mats — Air Sprung Cell mats and Self-Inflating mats. Used with an Air Sprung Cell mat, two or three cycles are enough to inflate the mat while adding minimal condensation. With a Self-Inflating mat, the pump will \"top off\" your mat quickly and efficiently. The lightweight 15D Ultra-Sil dry sack is large enough to store clothes or a sleeping bag inside a backpack.\u003c\/p\u003e\u003c\/div\u003e\n\u003c!-- KEY FEATURES PANEL --\u003e\u003cdiv class=\"tab-panel key-panel\"\u003e\n\u003cdiv class=\"key-section\"\u003e\n\u003cdiv class=\"key-title\"\u003e2-in-1 Design\u003c\/div\u003e\n\u003cdiv class=\"key-desc\"\u003eDry sack by day, sleeping mat pump by night.

The valve design is intentionally low-profile so the pump sack can be rolled up small when not in use.

Ultra-Sil is STS's lightest dry sack fabric line, balancing low weight with reasonable durability for the weight class. Not as tough as the heavier 30D\/40D Ultra-Sil variants, but lighter.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"key-section\"\u003e\n\u003cdiv class=\"key-title\"\u003eFully Seam-Sealed Construction\u003c\/div\u003e\n\u003cdiv class=\"key-desc\"\u003eThe dry sack is \u003cstrong\u003efully seam-sealed\u003c\/strong\u003e — every stitch line is taped or welded to prevent water ingress. Important for the pump function too — water that seeps through unsealed seams would be pumped into the sleeping mat, defeating the \"minimal condensation\" benefit.

Sized to fit inside most backpacks as a removable liner or top-pocket organizer. When rolled and clipped, the volume compresses to a very small package (27 × 1 × 17 in rolled).\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"key-section\"\u003e\n\u003cdiv class=\"key-title\"\u003eFast Inflation (2-3 Compressions)\u003c\/div\u003e\n\u003cdiv class=\"key-desc\"\u003ePer STS: \"two or three cycles are enough to inflate the mat.\" Each cycle = one roll-and-squeeze of the pump sack. The 20L volume is calibrated to deliver enough air per cycle to fully inflate most STS Air Sprung Cell mats (Ether Light XR, Ultralight Air, etc.) in 2-3 cycles. For thicker insulated mats, may require 4-5 cycles.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"key-section\"\u003e\n\u003cdiv class=\"key-title\"\u003eWhy \"Minimal Condensation\" Matters\u003c\/div\u003e\n\u003cdiv class=\"key-desc\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"key-section\"\u003e\n\u003cdiv class=\"key-title\"\u003eBreath vs Pump Inflation\u003c\/div\u003e\n\u003cdiv class=\"key-desc\"\u003eWhen you inflate a sleeping mat by \u003cstrong\u003ebreath\u003c\/strong\u003e (mouth-to-valve), you pump ~37°C humid air into the mat. As the air cools overnight, the moisture condenses on the inside of the TPU bladder. Over years of use, this moisture can degrade the TPU (hydrolysis) — the same failure mode that the TPU polyether laminate resists. \u003cstrong\u003ePumping with the Airstream Pump Sack uses ambient (room-temperature, dry) air\u003c\/strong\u003e, dramatically reducing the moisture that enters the mat.
