The AK70 is a large expedition pack suitable for climbs in the Greater Ranges. It can manage a heavy payload of 28–35 kgs in tolerable comfort (we are not going to pretend that this is ever an enjoyable amount to carry), but still remains light enough to be used for a summit push. Its large volume is ideal for stuffing bulky, frozen gear into, whilst semi brain-dead from oxygen deprivation and encumbered with big clumsy mitts. As well as being remarkably light for such a capacious pack, the AK70 is substantial enough to impart a feeling of solidity and security, to the point that some people have actually tried bivouacking in one(OK, they were desperate – it's not really big enough).
The AK70 is the first of the 2016 3G packs to employ a roll-top closure system under the hood, replacing the draw-cord system found on the 2015 styles. Uniquely within the AK range, the AK70 also features a dual-wrap hip belt. Although not heavily padded or particularly large, this transfers the load onto the hips very effectively and enables heavy loads to be carried with some small modicum of comfort.
The AK70 is available in three back lengths: 1 (women), 2 (medium) and 3 (tall). Size 1 is only available in red. Whilst these are available through our retailers, demand is outstripping our ability to make them, and stock is very limited.
PLEASE NOTE: The image shows the lid secured by G-hooks. These have now been replaced by alloy quick release buckles as can be seen on other AK styles
