Tyvek Sleeping Bag Cover "Nemuri Mamoru-kun" Silver - Right Side Double Zipper Ver.

We've made a sleeping bag cover using the well-known Tyvek Silver.
*This model features double zippers on the sides, allowing you to open it fully from the top or just slightly at the foot.

◑ This silver Sleeping Bag Mamorukun (Sleeping Bag Protector) is a sleeping bag cover designed for 4-season tent camping and winter camping.

By using the familiar Tyvek Silver, we've improved the heat retention compared to the conventional Sleeping Bag Mamorukun.

◑ Size: Laid flat, it's approximately 225cm long, with an opening of about 90cm, a foot width of about 65cm, and a gusset of 26cm.
Weight is approximately 265g (slight variations may occur).

◑ Our commitment to detail: We've widened the entrance to reduce stress when getting in and out, and tapered the width towards the foot to minimize wasted space and fabric, thereby reducing weight.
Additionally, as shown in the 4th photo, we've added reinforcement to areas near the entrance where stress is applied, and finished the sides with a bag seam for added strength. We also included a smartphone pocket inside, because I wanted one (this is important!).

*Wrinkles will appear due to the nature of the material.
*New products may have a characteristic smell of silver Tyvek, but this will disappear with sun-drying or use.
*There may be color transfer from prints onto the white surface.
*While the material is waterproof, the product is sewn and therefore not completely waterproof, so please be aware.
*The Tyvek logo will be printed on the inside.
*Please understand that it will be shipped folded compactly.
*Each item is made with care, but slight individual differences may occur. Those seeking perfection like mass-produced items should refrain from purchasing.
*It is possible to have the zipper placed on the left side. Please consult us in the comments if you wish.

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