Revolutionary sleeping bag that doubles as a cosy suit that you can walk around in!

The Onesie sleeping bag from Summit comes in large and has a height of 190cm. It also benefits from zip off feet sections, allowing you to pop your shoes on when you need to for improved freedom of movement, as well as zip enclosures for your hands to protect them from the cold. 

The sleeping bag has a soft 170T polyester lining and has a 3 season rating, making it suitable for camping in the UK during spring, summer and autumn. Guaranteed to be a hit at the camp site and ideal for keeping you warm when you want to sit outside your tent on an evening. 


The Summit Onesie features two zips on the front of the suit that allow you to open the front section to the waist so it's easy to get in and out of. Each zipper has a top and bottom zip which allows you to open it by the waist to get to your trouser pockets or for ventilation  without taking the suit off. At the top of the zips are velcro closure tabs to protect you from the zips and offer additional protection from the zip coming undone. The hood features twin drawcords to keep it cosy on your head. The foot sections can be zipped off completely if you are walking in the open and there are two zip openers by the hands.
