The Carp Spirit Blax Sleep Bag 3 Season is a very high quality sleeping bag that is good to use in spring, summer and fall. The outside of the sleeping bag is made of 190T polyester which is waterproof and keeps the cold and wind out well. The inside of the sleeping bag is made of woven polyester which provides excellent thermal properties and keeps heat well inside. Furthermore, the sleeping bag’s hollow fiber filling keeps it extra warm. The sleeping bag has a length of 220cm and a width of 95cm. This gives you just enough space to get in and out of the bag easily and at the same time it is long enough to cover your shoulders. The face/head section is left open so that the sleeping bag is very comfortable. Furthermore, the sleeping bag features 10mm robust zippers that are also very flexible. The sleeping bag can be attached to a stretcher with Velcro straps so it will stay in position even if there is a lot of movement during the night. The sleeping bag comes with a luxury carrying bag.
