Enjoy a high level of sleeping comfort inside the OZTENT Hamilton Standard Sleeping Bag. The XSIL brushed interior is designed with softness in mind to provide a great night's sleep. Full-length auto-lock zipper allows you to join 2 sleeping bags together (left- and right-side models) to double the width. Stay warm throughout the night surrounded by 300gsm Bonded T-Therm polyester fiber insulation. Chest and full-length side baffles promote insulation loft and prevent shifting. Use the drawcord closure to maximize warmth retention. Smooth gliding zipper technology with auto-locking sliders and anti-snag guards results in hassle-free operation where the zipper opens easily, but only when you want it to. Other highlights of the OZTENT Hamilton standard sleeping bag include 210 ripstop polyester outer shell, inner storage pocket, pillow pocket, double-cap stuff sack, and hook-and-loop closures at zip opening point.
