Sleeping bag cover, reduced drafts, Tyvek Silver, tyvek, with storage bag, 011

Super lightweight and compact, and highly popular!!
This sleeping bag cover is made from Tyvek for construction, featuring a design to reduce drafts around the shoulders. Includes a storage bag.

Compared to the standard version, one side of the shoulder flap is sewn shut, and the other side has added Velcro, allowing you to cinch it up like a cocoon to reduce drafts. Recommended for those who feel drafts around their shoulders!

The fabric has a crisp texture, so you won't feel suffocated even when inside.
The Velcro used is a type that is less likely to cause irritation.

We've shaved off excess shapes and parts to achieve ultimate lightness! The fabric is thick and tear-resistant, and the gusseted bottom means your feet won't feel cramped.
The flap at the entrance is reinforced, so it won't tear even with rough handling.

When used over a sleeping bag, it can add 5°C to the applicable temperature, and it's also suitable for sleeping in during the summer on its own.
(During a traverse of the Northern Alps and Southern Alps in August, I was able to stay overnight with just a stock shelter + mat + this cover.)

I used it for a trial period of 6 nights. I tend to sweat a lot, but the inside of the sleeping bag cover did not experience condensation. There was no difference in condensation whether it was sunny/rainy/dense fog, or whether a sleeping bag was used or not. My family also used it without any condensation.

I also used it twice for summer car camping, outside of mountain climbing. I slept with just the cover, and it was comfortable without condensation.
