It’s the perfect size to fit a 40 degree mummy bag. It fits in the Arc Blast nice and snug! Well made and is tough as nails! It’s nice to not have to worry about the sleeping bag if I get water in the pack.

Keep your gear dry when the weather is wet! The slim size dry bag will fit well in smaller backpacks. It is a good size for lightweight clothes, miscellaneous loose items, or a summer quilt. It is also useful to store flat items like a book, maps, or documents in an average depth backpack.

  • The bags have a stiffened opening to make rolling the top down easy and secure.

  • Squeeze out the air and roll down the top to compress your gear as needed.

1 oz/sqyd Dyneema® Composite Fabric has a thicker membrane giving it more abrasion resistance. We use it for dry bags and tent floors.
