Ease of Use

Using the Tuck 20 is just as simple as unfolding or unrolling it and getting inside. It must be rolled back into a tight form to put it in the included stuff sack, which was the most frequent concern and problematic issue for buyers. When the sleeping bag is in the stuff sack, it is in a compressed form, meaning the air is not in it. when it is out of the sack, the baffles gain air from the atmosphere and the bag becomes fluffy and full again. To get it back in the stuff sack was easy for some people and not so easy for others. A few decided to get larger bags for storing the item and transporting to make it easier to pack it away. Once the compressed product is in the stuff sack, it will fit in the smallest of spaces because it weighs less than four pounds. This terrific bag is roomy without being too big and has a strong zipper. The sturdy zipper is resistant to snagging, making it easy and simple to get in and out. One other concern of the Tuck 20 is that it is not machine washable in a top-loading washer. It must be washed by hand or in a front load washer because of the baffles and insulation. This would be ruined in a top-loading washer. It is well worth the extra care needed for such a comfortable, luxurious bag.
