Waterproof mummy-style bivy sack in army green
A compact, waterproof and breathable bivy sack made for mummy-style sleeping bags, with sealed seams, a side YKK zip and a packable carry size.
Litume’s sleeping bag cover is a compact bivy sack designed for use with mummy-style sleeping bags. It combines a waterproof and breathable fabric with sealed seams and waterproof zipper covers, giving you an extra layer of weather protection when conditions turn damp or unsettled.
The army green finish keeps the look understated, while the lightweight, packable design makes it easier to carry in a backpack without taking up much space. According to the listing, it folds down to 17.5 x 8.5 cm and weighs less than 400g.
Built for sleeping bag use
The shape is tailored to mummy-style sleeping bags, with a roomy footbox and an elastic drawcord at the hood for a closer fit around the head. A semi-open YKK side zip is included for access and everyday use.
What the material is meant to do
The fabric is described as waterproof and breathable, with a waterproof rating of up to 12,000mmH2O (JIS L1092B). The listing also says it helps wick away sweat and moisture, which is useful when you want to stay drier inside a sleeping setup.
Care and handling
- Hand washing is recommended to help preserve the waterproof coating.
- Machine washing is not recommended by the listing.
- The fabric is stated to be OEKO-TEX certified and made by eco-friendly manufacturers.
This is a straightforward outer shell for adding protection around a sleeping bag, rather than a bulky shelter system. The compact pack size and low weight will matter most to people who want something easy to carry and simple to stow.
