Sea to Summit Ultralight Backpacking Air Mattress Large 78 x 25 x 2 in

Overview

The Sea to Summit Ultralight Backpacking Air Mattress in the large size blends lightweight comfort with durable construction for fast and light adventures. With a warm season friendly R-Value of 1.1, this sleeping surface aims to keep you comfortable on milder nights while you explore backcountry trails.

Why this design feels right

The mattress uses Air Sprung Cell construction, which mimics a spring mattress by increasing the surface area that contacts your body and distributing pressure more evenly across the bed. The result can feel like steadier support and a more stable sleep surface when you set up camp after a long day.

• Ultralight profile with a 2 inch thickness for a compact, cushioned feel
• Single layer of cells keeps weight down without sacrificing comfort
• Non slip 30D/40D nylon face fabric is durable and quiet for peaceful nights

Inflation, deflation and control

Inflation is quick and easy thanks to the integrated Airstream Pumpsack, letting you top up with just a few breaths. A one way deflation feature supports fast pack up, while you can fine tune air pressure to your preference for comfort.

• Multi function valve enables fast inflation, exact pressure, and quick deflation
• Fine tuning lets you dial in the level of support you want
