I have bolted the straps from one of my sponsors, snowsled.com, to my Paris sleds. These straps prevent the entire bag from sliding out of the sled in case I tip it over or in the worst case, the sled falls through crevasse.
If my sled were to fall through crevasse and take all my gear with it, I would be in major trouble.
So, with a few straps bolted to the sled, this thing would be dangling in space. Hopefully it wouldn’t take me with it, though. But, since I have two sleds, that is hopefully less likely.
