This sleeping bag cover is lightweight and compact. Protects the sleeping bag from water and releases heat and moisture from inside the sleeping bag due to the breathable nature of the material. Cannot be used by itself and must be used with a sleeping bag. ※NOT completely waterproof. Breathability:7,000g/㎡ ·24 hrs (JIS L-1099 B-1 method)
Our Verdict
Montbell's Tyvek Sleeping Bag Cover is a great way of adding a layer of protection to your bag. Although the tyvek isn't fully waterproof it does a great job of keeping moisture off your bag whilst also being breathable enough to let out heat and moisture build up during the night. The tyvek material feels much softer and more comfortable than you'd expect and it certainly adds a significant amount of durability for your sleeping set up.
Weighing in at just 150g and compressing down to a decent size this is a great addition for keeping your sleeping bag in top condition for bivy and tarp trips.
