I'd hope that someone out climbing would have enough sense to realise they could strap something down other than a snowboard.
It's just a bag, you put stuff in it. You could put the poles in the side pocket where the water is meant to go.
What makes this good for climbing or hiking? It doesn't have any straps for hiking poles, climbing kit and the snowboard strap is redundant
It says that in the OP. (y)
