Tyvek Sleeping Bag Cover "Nemuri Mamoru-kun" ~Now with a Smartphone Pocket~

I made a sleeping bag cover using DuPont's Tyvek.

This Nemuri-gami-kun (Sleeping Bag Protector) is a sleeping bag cover designed for three-season tent camping.

For summer tent camping, I bring my NANGA Aurora 280DX. I want to keep my gear as light as possible, but it can get unexpectedly cold in the mountains, and I often wake up in the middle of the night.
So, I bring Nemuri-gami-kun with me as a protective charm.
By covering your sleeping bag with it, you can not only protect it from condensation that fills the tent but also improve its warmth retention.

Size: Laid flat, it is approximately 225 cm long, with an opening of about 90 cm, a hem of about 65 cm, and a gusset of 26 cm.
Weight is approximately 250g (slight individual differences may occur).

My focus was on widening the opening to reduce stress when getting in and out, and narrowing the width towards the foot to reduce wasted space and fabric, thereby achieving a lighter weight.
Also, as shown in the fourth photo, I added reinforcement to the areas near the opening where stress is applied, and finished the sides with a French seam for added strength. Additionally, because I wanted it, I placed a smartphone pocket inside (this is important).

*Wrinkles will appear due to the nature of the material.
*The material is waterproof, but please note that the product is sewn and therefore not completely waterproof.
*The Tyvek logo will be printed on the inside.
*Please understand that it will be shipped folded small.
*Each item is made with care, but there may be slight individual differences. Those seeking perfection like mass-produced items should refrain from purchasing.

*This is strictly a sleeping bag cover.
When using, please be sure to use it with a sleeping bag and sleeping system that are fully suitable for the environment.
