These days, it’s almost impossible to release a product that isn’t multi-function. It’s not good enough that your bottle opener, well, opens bottles; it also has to hold your keys onto your pants. Your fancy pen also has to have a stylus. Your bag has to transform and roll out into a duffle. Which brings us to Chrome’s Sotnik. It doesn’t transform and roll out, but it definitely rolls up (or down, technically) and can be used in hand, on the shoulder or even pack style. The outer shell is weatherproof 1000 denier Cordura grade nylon. The liner is waterproof 1800 denier military grade truck tarpaulin. In other words, the Sotnik is made to the same ridiculous standards–with the same awesome materials–as the rest of the Chrome bag catalog. What separates the Sotnik from everything else is the ease with which it converts from duffle to pack simply by changing the way you use the reinforced haul straps.
