For a lightly loaded day pack, determining the exact back length is not absolutely crucial. With trekking or mountaineering backpacks, however, it is essential, as only a perfect fit will efficiently transfer the weight to the hips. With heavy loads or backpacks featuring an internal carrying system, the centre of the hip wings should ideally rest on the iliac crest and the rear pad on the sacrum.
How do you measure back length?
To determine the back length, use a tape measure to measure the distance between the base of the shoulders or the level of the 7th cervical vertebra (which you can feel protruding where the neck meets the spine) and the upper edge of the iliac crest.
The Lightning, Ridgeline and Skyline rucksacks are fitted with a unisex carrying system. They offer two adjustable back lengths: S | M and L | XL.

Product Description
With its ultra-lightweight construction and adjustable back system, the Lightning was developed for trekking tours where low weight and high carrying comfort are crucial.
The innovative T-Rex carrying system with reduced contact points ensures effective ventilation and freedom of movement. The back length can be precisely adjusted, while the efficient load transfer to the hip belt ensures a stable and comfortable fit even with a heavier pack weight.
Sophisticated pack volume management allows flexible adjustments. The zig-zag compression straps are easy to adjust and, together with the roll-top fastener, allow variable volume control. They also secure larger equipment such as a sleeping mat or flysheet. Generous mesh outer pockets, zipped pockets on the hip belt and modular attachment points support clear organization.
Made from ultra-light ripstop nylon with a reinforced polyester base, the Lightning combines minimal weight, durable performance and well thought-out design.

Ik heb een waterfilter gekocht. Er was een kleine vertraging bij de levering, maar het Hillmalaya-team heeft het snel opgelost. De service is heel goed 👍. Verder ga ik bij mijn volgende aankoop absoluut geen JD Express (京東快遞) meer gebruiken, het was echt enorm ergerlijk!
Snelle en efficiënte levering. De producten zijn goed en komen overeen met de getoonde afbeelding. Bedankt

Ik koop al mijn trailrunningkleding en -uitrusting bij Hillmalaya. Onlangs hebben ze mijn Maurten gel verwisseld met een ander model. De winkel reageerde snel met een geweldig aanbod! Ik raad iedereen van harte aan om hier te genieten van een fijne winkelervaring.

Ik ben erg blij met deze opvouwbare trailstoelen. Deze keer heb ik er 2 gekocht, naast de 4 andere die ik thuis heb. Ik gebruik ze om te zitten bij klusjes in huis, vooral dicht bij de grond, bij het tuinieren (onderste takken snoeien) en om in het park te zitten voor buitenfotografie, vooral als ik op vogels wacht. Hierdoor hoef ik niet meer lang te hurken, wat niet goed is voor mijn knieën en benen naarmate ik ouder word.

I like these foldable trail chairs very much. I bought 2 this time round in addition 4 others at home. I used it to sit down to do chores at home especially at low level, gardening (trimming lower branches) and sitting in the park for outdoor photography especially waiting for birds. This reduces the need to squat for long periods of time which is not good for my knees and legs as I grow older.
