We don’t like mesh for pockets in a rucksack; it gets ripped, clings to sharp edges and offers the least protection of all fabrics. So we made removable pockets, with a transparent front, colored coded and in two different sizes. With the Velcro strips you can fit them anywhere in your pack. 2 Small and 3 large pockets come standard with the pack
We do not use waterproof zips on purpose. What is the use of it when the seams of your pack are not taped to be fully waterproof? So it is fashion and expensive not function. That's why we use the best zips around: heavy and reliable YKK 10 zips for us with simple and repairable pull-ties.
Internal tension releasing system
We placed four internal tension releasing straps, two on each side. Use the internal straps to reduce the tension on the zips. When your pack is loaded with long and heavy lenses, your gear is pushing outwards – this is when zips are giving in, the weight tries to pull them apart. So reduce the tension with the internal straps.
Hip belt & shoulder straps
First we came up with a removable hip belt because it is comfortable and easy when travelling. But we fount a better solution: a lightweight though very functional belt. No thick padding here that will add up to the size but a very well pre-formed adjustable hip belt. The shoulder straps can be compressed but not stowed away; I never use this feature as I mostly carry the pack on the shoulders.
The Spitsbergen has one compartment on one side and two on the other side. If you want to carry two long lenses, you can join the smaller compartments into a big one. Just open the divider between the two and you can place another big lens in the pocket. The Boris II and Bertik just have two big compartments and a lot of dividers.
12 dividers in 3 sizes – small red, medium grey and the large one black coloured with wide velcro strips and 10mm High Density foam padding for ultimate flexibility. The inside of the packs are made of the 'loop side' of velcro so you can stick them in any position in the pack.
