Crux AK70

Lightweight bombproof expedition pack.

The Crux AK70 is a large capacity (70+7 litres) rucksack for serious expedition use but still at a weight that won't cripple on a summit push (only 1500g even before you remove the floating lid). It will cope with heavy loads up to 30kgs and has an excellent harness.

The AK70 has all the same great features as the Crux AK57 and is built to withstand the knocks and scrapes of serious expedition life, but it won't slow you down. Hence the Crux AK70 is a must have pack for the discerning expedition traveller, climber and mountaineer.

With minimal seams and zero fuss design mean minimal weaknesses, which when combined the choice of Kevlar/Cordura materials make it bomber. The harness, ultra light M-Frame combined mouldable titanium stay and ergonomic shape mean that the carry is super comfortable, well balanced and unrestrictive even with loads reaching 30kg. The waist-belt is very low profile giving little interference with harness and clothing and includes loops for attaching gear loops if required.

The floating lid means that an extra 7 litres capacity is available. The lid is also removable meaning that the pack can be paired down for summit day.

The size of the pack make it ideal for big trips into remote areas where you need a lot of kit, but where you still need to perform at your best. The pack features side ski mounts making it ideal for serious ski mountaineering as well.

The excellent fit and carry is achieved by clever design, high surface contact with your back, load carry close to your back and the use of 3 different size options:

Size 1 is optimised for women but also fits small men with a 45 cm back length and a typical height range of 160-170cm.

Size 2 suits a 50cm back length and a typical height range of 170-180cm.

Size 3 suits a 55cm back length and a typical height range of 180-190cm.

Please note that back lengths are measured from the top of the pelvis to the top of the shoulder and that height range is only a guideline and may not be right for your particular proportions

When fitting a pack the hip-belt should wrap around the top of the pelvis, so that the hips are able to share the overall load. Some climbers, however, prefer to carry their rucksack around their waist, i.e. above the pelvis and may prefer a rucksack with a shorter back length.

Both Crux and Up and Under recommend whenever possible trying on rucksacks before making your final choice. By all means order 2 different sizes and use our returns procedure to send back the least suitable size.
