Description

Sea to Summit Ether Light XT Insulated Sleeping Mat

Lightweight Insulated Comfort for Cold-Weather Adventures

Designed with extra-thick Air Sprung Cells™, this mat provides a plush 10cm of cushioning—perfect for side sleepers who need extra support without feeling the ground beneath them. Whether you’re trekking through alpine environments, embarking on a winter camping expedition, or simply seeking superior insulation for chilly nights, the Ether Light XT Insulated is built to deliver premium performance.

Innovative Design for Maximum Comfort & Warmth

The loop baffle Air Sprung Cell™ construction creates larger, more stable air pockets by utilizing TPU-bonded baffles that connect the top and bottom layers. This design not only increases comfort but also minimizes fabric use, keeping the mat lightweight yet supportive.

For enhanced warmth, the mat features Exkin Platinum® insulation, which reflects radiant heat back toward your body, and THERMOLITE® insulation, which traps warm air within the mat’s structure. With an R-Value of 3.2, this mat provides reliable insulation for three-season adventures and mild winter conditions.

Effortless Inflation & Practical Features

  • Airstream™ Pump Stuff Sack: Integrated into the included stuff sack for fast, easy, and moisture-free inflation.
  • Multi-Functional, High Flow-Rate Valve: Allows for quick inflation, easy deflation, and micro-adjustments for personalized comfort.
  • Ultra-Fresh® Anti-Microbial Treatment: Prevents internal mold growth for long-lasting durability.
  • Lightweight & Quiet 30D/40D Nylon Fabric: Designed to be grippy, durable, and field-repairable with the included self-adhesive patches.
  • PillowLock™ System: Securely holds your Aeros™ Pillow in place to prevent nighttime slipping.
