The backpack has a simple design and an increased volume is 45 litres. Entrance to the main body compartment is on the roll top, it's made for quick access and easy volume adjustment. 

The unique design has simple roll top construction which can be fast loading and easy adjustment of the volume.

The backpack helps to improve your speed, efficiency, increase hiking distance and pleasure from the mountains. Ideal choose for those who want to save every gram in their gear.

A feature of the backpack is the removable straps of the side version of the rolltop, the central strap and the load-lifters straps. That's maybe customize the backpack just for you.

The backpack has frameless design. For the forming the frame of the BIGGIE PACK we recommend to use a sleeping mat, putting it along the back of the backpack.

In contrast of the Elementum, the Biggie Pack hasn’t got a front compartment made of elastic material, but it has a large front pocket made of Ultra™ 200.

There are some holes for water drainage in the bottom part of Pack.

The lacing system of the front pocket can be used for drying clothes and gear during the transitions or for additional fastening of equipment at the trail.

The backpack has 7 pockets: a central large front pocket, two voluminous pockets on the backpack belt, two side pockets and two updated pockets on the straps.

New mesh pockets on the shoulders straps: increased volume, now the pocket is fixed with a tightening system, and the pocket can also be closed/opened with one hand. These pockets will soon migrate to the Biggie Pack 65L.

The backpack has a removable load-lifters system on the shoulder straps and in the upper part of the backpack. 

Lacing is provided for attaching additional gear on the sides and in the lower part of the backpack.
