Sleeping bag COCOON ST40 adult rectangular 900×2200 mm, 160 g, silk brown

COCOON ST40 adult rectangular sleeping bag liner is a lightweight, compact sleep sack designed for travel and simple overnight protection. Made from fine silk fabric in brown, the liner measures 900×2200 mm and weighs 160 g. It is supplied in a small storage pouch (145×65 mm) for easy packing, and can be used alone in warm conditions or as a hygiene liner inside a conventional sleeping bag to extend cleaning intervals.

Advantages

The silk fabric offers a smooth, breathable surface that regulates microclimate next to the body and feels comfortable against the skin. At 160 g and with a compact carry pouch, the liner is easy to stow in a backpack or luggage and adds minimal bulk. Its rectangular shape provides extra room to move compared with mummy-style sacks, and the generous length accommodates taller users. The neutral brown colour is practical for travel and repeated use.

Suitable for

• Traveling — planes, trains and hostels
• Backpacking and lightweight trekking where low weight matters
• Camping in warm climates or as an inner liner for added hygiene
• Use in alpine huts, boats and shared sleeping spaces

How to use

Unfold the sleeping bag liner and slip inside with head through the open end. For sleeping directly in the liner, fasten the top edge if the design permits and adjust for comfort. When used as a liner inside another sleeping bag, place the COCOON ST40 inside the larger bag with seams aligned and ensure the foot end matches to avoid bunching. After use, air the liner to remove moisture, then hand-wash or machine-wash on a gentle silk or delicate cycle following fabric care instructions, and allow to air-dry completely before packing.

Lietošanas ieteikumi

For long-term hygiene in hostels or frequent travel, use the silk liner each night and launder regularly. Avoid contact with sharp objects and rough surfaces to preserve fabric integrity; repair small snags promptly. For cooler nights, combine the liner with an insulated sleeping bag rather than relying on the liner alone.
