The Sonik Bank-Tek 5-Season Sleeping Bag is built for maximum insulation and all-year-round use, keeping you warm in demanding conditions. Its water-resistant, hard-wearing, and breathable 190T ripstop fabric is paired with a high-quality silicone-treated hollow fibre fill that maintains its loft for effective heat retention. A new hood design offers versatility and adapts to your preferred sleeping position, while the fleece-lined upper adds warmth and the smooth polyester-lined base allows easy movement inside the bag. The head and foot sections both feature drawstrings to thicken insulation and eliminate cold spots, and a wide fold-out mosquito head net proves useful on calm summer nights. - Water resistant 90T Ripstop outer material - Full 5-season thickness insulation - High quality silicone treated hollow fibre fill - More efficient internal zip baffles - New improved head and foot hood design - Removable elasticated centre strap - Oversized No. 10 coil crash zips with wide webbing anti-snag guides - Smooth polyester lined base for easy movement - Micro-fleece lined top cover with smooth stubble guard neck lining - Foot drawstring to eliminate cold spots - Fold out mosquito head net panel - Internal hand warmer pockets/neck baffles - Pillow retaining hood with effective drawstring compression system - Full compression bag
