Sleeping bag SEA TO SUMMIT Breeze Mummy Tencel/Polyester, 80 x 2250 mm, 330 g

The Sea to Summit Breeze Mummy liner combines breathable COOLMAX® EcoMade and soft Tencel Lyocell fibres to wick moisture and maintain comfort on warm nights. Designed for lightweight travel and camping, the mummy-shaped liner measures approximately 80 mm in width profile and 2250 mm in length, and weighs about 330 g. Its stretchy construction and functional openings let you use it inside a sleeping bag or on its own for additional hygiene and comfort.

Advantages

COOLMAX® and Tencel fabrics work together to provide climate control by moving moisture away from the body, while the super-stretch fabric gives freedom of movement whether you sleep still or turn frequently. The liner includes odour control treatment to stay fresher between washes, a drawcord footbox and technical hood for ventilation and mobility, and a pillow sleeve on the traveller version. It is machine washable, quick-drying, and made with lower-impact recycled and bluesign APPROVED materials to reduce environmental impact.

Suitable for

• Lightweight backpacking and travel where pack weight and compactness matter
• Warm-weather or three-season camping to improve comfort and hygiene
• Use inside a sleeping bag to reduce washing and extend the bag’s lifespan
• Independent use as a lightweight liner or sleep sheet in hostels, huts, or warm climates

When it may not be suitable

This liner is designed for comfort and moisture management in warm to moderate conditions and is not intended as primary insulation in cold weather. Its薄ker construction and breathable materials will not provide significant thermal protection on their own in low temperatures.
