Sleeping bag SEA TO SUMMIT Breeze Mummy Tencel/Polyester, 80×190 cm, 265 g, Blue

The SEA TO SUMMIT Breeze Mummy is a lightweight mummy-style sleeping bag liner made from a breathable blend of COOLMAX® EcoMade and Tencel Lyocell fibres with a polyester shell. Measuring 80 × 190 cm and weighing 265 g, it offers compact packability and moisture-wicking comfort for warm-weather camping, backpacking and travel. Designed for solo use, the liner adds a hygienic, quick-drying layer that helps reduce washing of your sleeping bag and prolongs its lifespan.

Advantages

The Breeze combines COOLMAX® EcoMade and Tencel fibres to wick moisture and promote climate control on warm nights. Its super-stretch knitted fabric and technical openings—drawcord footbox (mummy), hood and shoulder Climate Control openings—provide freedom of movement whether used inside a sleeping bag or on its own. The liner features HeiQ Fresh odour control, is machine washable, quick-drying and constructed from lower-impact recycled and bluesign APPROVED materials.

Suitable for

• Warm-weather camping and backpacking
• Travel and hostel stays where a clean sleeping surface is desired
• Use as an internal liner to reduce washing of an insulated sleeping bag
• Single-person use where a lightweight, compact liner is required

When it may not be suitable

This liner is designed primarily for warm conditions and breathability; it does not provide significant thermal insulation by itself and should not be relied on as a primary insulating layer in cold weather. If bulk insulation or very low-temperature ratings are required, choose a dedicated insulated sleeping bag instead.
