The Fox Ventec All Season Sleeping Bag is designed to work as both a 3 season and a 5 season bag in one. It includes a zipped-in, removable thermal inner bag; taking the inner bag out converts the setup from a very warm 5 season option to a comfortable 3 season sleeping bag. The inner bag is fully reversible, offering a micro fleece base layer with a sherpa fleece upper layer on one side, or a polyester lining on the other, so you can choose the feel you prefer. The outer 3 season bag uses a polyester mid-section with micro fleece head and foot sections for added warmth and comfort, all wrapped in a Ventec water resistant outer fabric. The construction benefits from 7 Core Hollow Fiber filling, which is silicone treated to help maintain shape and expand fibres, while offset panel stitching keeps warm air inside. Non-snag, heavy-duty crash zips, anti-snag polyester guard webbing, and oversized internal fleece baffles round out the design. A pillow retainer sits on the base layer, and the bag features head and foot section hoods plus an elasticated webbing strap to secure it to most bedchairs. Head and foot sections also include cut outs so the bag can be used on beds with single legs at both ends.
