Product Details

As you all know, I've made a sleeping bag cover using Tyvek Silver.

This Sleeping Bag Mamorukun (Sleeping Bag Protector) is a sleeping bag cover designed for four-season tent camping and winter camping.
By using the well-known Tyvek Silver, we have increased the heat retention compared to the conventional Sleeping Bag Mamorukun.

Size: Approximately 225cm long, 90cm wide at the entrance, 65cm wide at the hem, and a gusset of 26cm when laid flat.
Weight: Approximately 250g (slight individual differences may occur).

Our commitment: We've widened the entrance to reduce stress when getting in and out, and narrowed the width towards the foot to reduce wasted space and fabric, thereby achieving weight reduction.
Additionally, as shown in the fourth photo, we've added reinforcement to areas near the entrance where stress is applied, and finished the sides with a French seam for strength. I also added 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 side.
*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 compactly.
*Each item is made with care, but there may be slight individual differences. Please refrain from purchasing if you are looking for perfection like mass-produced items.

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

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
