You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

    Sizing Information

    Crux Back Sizes and Fitting

    Rucksacks are either size 1, 2 and 3, or Regular (R) and Long (L).

    Where rucksacks only come in one size, this is equivalent to a Regular.

    Size Backlength Typical Height Range
    1* 45cm 160cm - 170cm
    R 48cm 155cm - 175cm
    2 50cm 170cm - 180cm
    L 55cm 175cm - 185cm
    3 60cm 180cm - 190cm

    * Size 1 is optimised for women, but fits small men also.

    Please note: The height range given for each back length is only a guideline and may not be right for your particular proportions. Crux always recommend trying on their rucksacks before you make your final choice.

    Typically, the hip-belt should wrap around the top of the pelvis, so that the hips are able to share the overall load (see diagram). But you may wear your rucksack differently, and this will also affect your choice of size. For example, some climbers carry their rucksack “high” – in other words, around their waist and thus above the pelvis – and may prefer a rucksack with a shorter back length.
