    My new go to backpack

    Great backpack for winter walking holding axes and all you're winter equipment expands to have plenty of space and is comfortable in the back when fully loaded with a handy side zip to get an at you're lower down items. It's carried on its use into camping and climbing it's so versatile will all the straps that can be tucked away when there not needed but pull out to hold ropes or any other gear you need to hold outside the bag. Will fit a 3l water reservoir inside too.
    Has become my favourite backpack.

    Nearly a great rucksack, dangerous design flaw

    First impressions was this is a great rucksack for overnight alpine routes, and I have used it happily enough for a year.

    I'd have preferred wand pockets for securing tent poles or walking sticks better.

    However, I have to revise my opinion because of the ice axe carrying system. I had secured a single axe, sack about 2/3 full, and had it detach itself and fall down the mountain when doing a climbing traverse under overhangs. My partner saw what happened, the end of the axe came out of the orange loop, because the distance between head and axe loop attachment is too short. I had to finish the route with no axe, including crossing a bergschrund and travelling on a crevassed glacier.

    So bargain sack, but false economy at less than half the price of the axe that fell off it.

    Brand response :

    Hello Max,

    I am very sorry to hear that the Jorasses Backpack 40L did not meet with you expectations and put you in a dangerous situation.

    I have given this feedback to the Product Designer for Backpacks at Simond. We are currently updating our range of backpacks with the first new ones expected in store this winter.

    In the meantime you can take the backpack to your local store, with receipt, and either exchange it for other products or a refund.

    Once again I am sorry the Jorasses Backpack 40L was not up to the standards you required.

    Kind Regards

    Does what it says on the tin.

    Possibly attaching elastic to the outer top pouch. Outer mesh/cargo net attachment.
