Our top-of-the-range sleeping bag & the biggest measuring an impressive 100cm wide by 220cm long. A major feature of this Bag is the Ven-Tec material used on the outer layer. This is the same material we’ve used on all of our new top-end domes, simply because it’s the best in terms of being extremely waterproof & breathable. We’ve yet to find a better material! It also comes with a removable & reversible inner bag. It’s reversible in the way that it’s polyester on one side & fleece on the other, meaning you can take your pick depending on what material you prefer the feel of. You can also take it out completely during warmer weather, use it as a duvet or blanket to use between the main bag & bedchai or have it fully zipped in. Other key features include: High grade silicone treated hollow fill fibre – helps fibres expand quicker & for longer Off set panelling construction prevents heat loss through stitch lines Reinforced Oxford Nylon 420 denier base Elasticated hoods top & bottom with offset central fixing to bedchair Heavy duty anti-snag internal zip baffle Internal & external draft proof baffles Double 10mm quick release zips Stuff bag
