Available in 2 sizes – medium which is 180 x 65cm and large which is 200 x 65cm in size. 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.
