The Sea To Summit Ether Light XR Pro Insulated is a four-season sleeping mat with 10cm of cushioning. Air Sprung Cells provide support, while dual-layer Thermal Core insulation and reflective film help reduce heat loss within the mat.
The lightweight construction uses 30D nylon on top and a tougher 40D base with TPU. A quiet, slightly grippy surface helps reduce sliding, and an internal antimicrobial treatment helps prevent mould growth.
Starting at 780g in regular, the XR Pro balances cold-weather insulation with packability for winter bivouacs and comfortable basecamp stays. The integrated pump sack and high-flow valve simplify inflation, while the Pillow Lock system helps secure a compatible pillow.
