Cocoon Mummy Liners

  • Sale
  • £45

A sleeping bag is a huge investment. A liner will keep it clean and comfy for years to come, plus a silk liner will add up to 5°C to the temperature rating of your sleeping bag. All the OP team have used one of these for years. If you’d like anything else from the Cacoon range - a merino or thermocline version for instance - then do let us know,.

They say:

Extremely lightweight, tapered sleeping bag liner that keeps your sleeping bag clean and adds insulation and comfort.

High quality silk is the optimum fabric for minimizing packing size and weight. Silk is breathable, soft to your skin and responds well to changing temperatures. It keeps you cool in the tropics and toasty in the mountains.
Hand or machine wash (30°C; gentle cycle) with mild detergent or dry clean. Do not bleach or use stain remover. Wash separately. Rinse in cool water and add a little vinegar to maintain shining colors. Drip or tumble dry low. Do not wring.
