If you're looking for a lighter sleeping bag that can take you through the warmer end of spring to autumn, the 2.5-season Sea to Summit® Traverse 25°F Synthetic Mummy Sleeping Bag is a great choice for you. This sleeping bag has a 25°F low-temperature rating thanks to a durable 30-denier nylon shell and Thermolite® polyester insulation. The insulation utilizes WaveLoft™ construction, which maximizes loft and minimalizes weight with curved insulation layers that expand out from the shell to trap air. The shaped mummy hood and zipper draft tube also boost this Sea to Summit sleeping bag's warmth. Find your perfect setup with this sleeping bag's full-length left-side zipper, half-length right-side zipper, and foot-box zipper that allows for air ventilation. The full zipper can zip up with any Sea to Summit Altitude, Journey, or Venture sleeping bag (not included) for a double-sized sleeping bag for 2. Includes a 70-denier nylon compression sack.
