◢ As you all know, I made a hoodless sleeping bag cover using Tyvek Silver. ◑ This, the silver "Sleeping Bag Protector," is a sleeping bag cover designed for 4-season tent camping and winter camping. By using the well-known Tyvek Silver, the insulation is improved compared to the conventional "Sleeping Bag Protector." ◑ The size is approximately 175cm in length when laid flat, with an entrance of about 90cm, a base of about 65cm, and a gusset of 26cm. The weight is approximately 215g including the stuff sack. (There may be slight individual differences) ◑ The focus is on widening the entrance to reduce the stress of getting in and out, and narrowing the width towards the foot to reduce unnecessary space and fabric, thereby reducing weight. Also, as shown in the fourth photo, reinforcement is added to the areas around the entrance that are subject to stress, and the sides are finished with a bag seam to increase strength. And because I wanted it, I placed a smartphone pocket on the inside (THIS IS IMPORTANT). ※ Wrinkles will occur due to the characteristics of the material. ※ New products have a unique smell of silver Tyvek, but the smell will disappear with sun drying or use. ※ There may be color transfer from the print on the white surface. ※ Although the material is waterproof, please note that the product is not completely waterproof because it is sewn. ※ The Tyvek logo will be printed on the inside. ※ Please understand that it will be folded small for shipping. ※ We make each item with care, but there may be slight individual differences. If you are looking for perfection like a mass-produced product, please refrain from purchasing. ※ Items other than the sleeping bag cover are not included. ※ This is just a sleeping bag cover. When using it, be sure to use it with a sleeping bag and sleeping system that are fully compatible with the environment.
