Crux AK47 RT

Be the first to review this product
The Crux AK47 RT is a super-tough rucksack that utilises a Kevlar-based fabric construction whilst weighing in at just under 1.2kg. This means it's it's built to withstand the knocks and scrapes of demanding climbs, but it won't slow you down. Hence the Crux 3G AK47 RT is a must have pack for the discerning Alpinist.

All variants out of stock


The 3G AK47-RT is the new icon of the Crux range and is now in their 3rd iteration of the 3rd generation (hence the 3G suffix). The changes for this version are few but are extremely significant as the amount of Kevlar used in the body fabric has gone from 28 to 40% - bumping up durability, plus the minimal seams are now welded making the pack properly water-resistant. The axe carrying system has also been improved to cope with all modern tools.

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

The size of the pack makes it ideal for day routes where you need to carry plenty of gear, winter climbing and single or multi-day Alpine rock, snow or mixed routes. Having said that when it's empty it is so light you will hardly notice it. The backpack features side ski mounts making it ideal for 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 2 different size options:
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.

Crux AK70 RT

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, but still remains light enough to be used for a summit push. Its large volume is ideal for stuffing bulky, frozen gear into.
