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.

Ich bin zufällig auf die Hillmalaya-Website gestoßen, als ich nach einem neuen Kanken No. 2 Rucksack suchte, um meinen jetzigen zu ersetzen. Ich bin beeindruckt und angenehm überrascht, wie unkompliziert das gesamte Erlebnis war – vom Bezahlen bis zum Erhalt des Pakets in meinem Briefkasten nur wenige Tage nach der Bestellung, obwohl es ein internationaler Versand war. Danke, Hillmalaya!

It was a chance encounter to the Hillmalaya website as I was looking for a new Kanken No. 2 bag pack to replace my current one. Impressed and pleasantly surprised by how fuss free the entire experience was, from checking out to receiving the parcel in my mailbox just days after ordering despite it being international delivery. Thanks Hillmalaya!
