Additional equipment is the Belt Bag that can be attached onto the belt. The main pocket is a hardcase made from foam where you can fit your ration and extra smaller equipment. Inside the bag there is separate room for mobile phones. On the outside of the bag there is made room for one bottle that can be safely secured with an elastic line. The Belt Bag also fits the Trekking belt model.
You can put a 0,75l bottle in the drink holder and secure it so it will not fall out.
With this hole in the top of the belt you can loop through your audio cable, your camelback line or whatever you may need.
The Ferd- and Trekking Belt can be equipped with the optional Belt Bag, which adds a additional pocket and drink holder. It's easily attachable and also can be removed very fast.
