This rucksack has Berghaus's "freeflow" back ventilation system which helps avoid a perspiring back when wearing the rucksack.

It is very comfortable to wear, and versatile, in that it is easy to expand the capacity of the rucksack from 35 litres to 43 litres by unzipping the zips at each side of the bag to allow you to get more in, should you need to do so, Obviously you can then compress the rucksack using the 2 compression straps at each side.

On the top lid of the ruck sack is a small zipped pocket with the rain cover inside, plus a separate small zipped pocket with a key clip for small items like a wallet or phone etc.

Underneath the lid is a separate small zipped pocket (i.e. inside the main body of the bag) which provides more security if you require this.

The bag has an internal pocket to house a drinks bladder, and there is facility to route the pipe through the H2O port and attach the mouthpiece to the shoulder strap. (No bladder is included).

The bag has two velcro fasteners to carry telescopic walking poles and an external rubber bungee cord add additional carrying flexibility.

Two straps at the bottom of the rucksack will allow the carrying of a rolled up sleeping mat or similar.

Shoulder straps are "micro-breathe" fabric and there is a belt and sternum strap.
