hi i am looking for a camera rucksack for when i go traveling. the ruck sack needs to be able to take my canon 7d and several lenses. it also needs to be water prrof and shock proof as i wish to take it when i go snowboarding. as the price i dont have huge amounts to spend .
any advice for which ones to look at or a good site which has a good range of reviews would be a great help thanks
