I bought 2 bundles of the folding poles and Diadem daypack for upcoming hiking trip in Scotland. I am sure the poles will be great. It is possible to make the filing poles shorter than 115cm— just unfold them, tighten them into place and simply don’t extend. Re: the daypack— I had to buy a separate rain cover which is fine and cheap enough to do. The little Velcro tab meant to hold the camelbak is not strong enough to hold it up when full so it does sag downwards. But if you hook the plastic opening over the sleeve, it should hold hopefully.
