I’ve mentioned it more than a few times in my stories, but the sledge bag is a hugely important bit of kit on a sledge. It’s typically made of canvas, and looped over the “uprights” at the back of the sledge with handles sewn from webbing straps. I made my own, but this one is better. 😉 Uprights are basically the sides at the very back of the sledge you hold onto when pushing the sledge.
You can keep all kinds of goodies in a sledge bag, and the softer the contents, the more comfortable it is to rest against when sledging.
