Sleeping bag liner COCOON TravelSheet Coupler Silk/Cotton with two-way zip, natural

COCOON TravelSheet Coupler Silk/Cotton is a lightweight sleeping bag liner made from a silk and cotton blend with a two-way zipper that allows convenient entry and the option to couple two compatible liners together. The blend combines the smoothness and breathability of silk with the natural softness and durability of cotton to improve hygiene, add a comfortable inner layer to an existing sleeping bag, and reduce the need for frequent washing of larger sleeping bags. The slim profile and low weight make it suitable for travel, hostels, and warm-weather camping where a light, breathable liner is preferred.

Advantages

The silk/cotton blend provides a soft, breathable sleeping surface that reduces moisture buildup and skin irritation compared with sleeping directly on synthetic bag interiors. The two-way zipper offers flexible access from either end and enables two liners to be joined into a double-width cover when needed. Its compact size when packed and low weight make it easy to carry in a backpack or luggage, while the natural materials are comfortable against bare skin and suitable for use in warmer conditions.

Suitable for

• Backpacking and lightweight travel where minimizing weight and pack volume is important
• Hostel stays and shared accommodation to maintain personal hygiene
• Warm-weather camping when added comfort without heavy insulation is desired
• Coupling with another compatible liner to create a double sleeping surface

Key specifications

• Fabric: silk and cotton blend for a balance of smoothness and absorbency
• Closure: two-way (bi-directional) zipper for entry and coupling
• Fit: designed to fit most travel and camping sleeping bags and mattresses
• Weight: lightweight and compact for easy packing (exact weight varies by size)
• Care: machine wash or gentle hand wash depending on fabric care instructions

How to use

Unpack the liner and align the zipper with the opening of your sleeping bag or lay it directly on a sleeping surface. Enter the liner through the zipper opening and close the zipper to secure it around you. To create a double sleeping surface, align the zippers of two compatible Coupler liners and connect them using the bi-directional zipper system. Follow garment care instructions for washing and drying to maintain fabric integrity and hygiene.

Usage recommendations

Use the COCOON TravelSheet Coupler Silk/Cotton in warm to mild conditions or as a hygiene layer inside an insulated bag in cooler weather. Pack the liner in a dry bag or storage pouch when not in use to protect the fabric, and air-dry fully after washing to preserve the silk/cotton blend.
