A quilt-pad attachment system lets you connect the sides of a backpacking quilt to the top of your sleeping pad so that drafts can’t sneak under the sides and chill you. Most pad attachment systems have elastic straps that you loop over a sleeping pad with clips that connect to the sides of your quilt. The male parts of the clips connect to female clips sewn onto the quilt. These are small and barely noticeable. All pad attachment systems are more effective when used in conjunction with a back tensioning system. In warm weather, most people skip the pad attachment system, but it is useful when it’s colder outside at night.
