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.

Compré un filtro de agua. Hubo un pequeño retraso con la entrega, pero el equipo de Hillmalaya lo resolvió rápidamente. El servicio es muy bueno 👍. Además, la próxima vez que compre no volveré a usar JD Express (京東快遞) bajo ningún concepto, ¡fue muy exasperante!
Entrega rápida y eficiente. Los productos son buenos y coinciden con la imagen mostrada. Gracias

He estado comprando toda mi ropa y equipo de trail running en Hillmalaya. Hace poco confundieron mi gel Maurten con otro modelo. ¡La tienda respondió enseguida con una gran oferta! Recomiendo muchísimo a todo el mundo que disfrute de una gran experiencia de compra aquí.

Me gustan mucho estas sillas plegables para trail. Esta vez compré 2, además de las otras 4 que tengo en casa. Las uso para sentarme al hacer tareas en casa, sobre todo a ras de suelo, para la jardinería (podar las ramas bajas) y para sentarme en el parque a hacer fotografía al aire libre, especialmente cuando espero a las aves. Así evito tener que estar en cuclillas durante largos periodos, algo que no es bueno para mis rodillas y piernas a medida que me hago mayor.

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.
