Based on Deuter's popular Guide, only much, much smaller, the Climber is a real rarity - a proper mountain pack that's aimed specifically at children. Comfortable, durable, and well-designed, it makes a reviewer's life too easy, says Dan Bailey, because there's really nothing to criticise.
My son has this pack; overall i agree with your test. I generally only miss one thing: Some straps to carry skis like an A-Frame. Maybe just over the strech pocket for bottles.
One quick tip for this pack and a lot of others: When the pack is half-empty, store the brain inside the main compartment. Less flopping around and a smoother outer.
This review was really helpful and I’m likely to buy this for my 8 year old - as with proper weatherproof clothing most child sized items are not really fit for purpose for a proper day (or night) in the hills
