I've currently got a Karrimor Orbit 40 which I was quite happy with apart from one thing - the straps stink. I've put it in the washing machine (in a laundry bag so the straps don't get caught on the machine) and the straps still stink. Don't know what else to do with it, it was left idle for a while and the straps stopped smelling but as soon as they got wet the smell came back.
So I need a new one. A day pack. Hopefully without thick absorbent straps. Probably don't really need 40 litres as I've never filled it to capacity but I like having the extra room in case I ever decide to take a stove with me. I also carry 2-3 litres of water which takes up a fair bit of room. 40 litres was the biggest they did without a waist strap which I don't want. Maybe 30 would be sufficient? I want something the straps aren't hugely thick and absorbent on or I'm going to have to same problem. I'm not sure what else to look for in a backpack really, I've been told a good walking backpack allows the air to flow through to your back but I've never had a problem with this.
Anyway I'm going to go have a look around Go Outdoors tomorrow but I wondered if the forum had any wisdom for me on what I should get?
