I got this to use as a toiletry bag for the climbing gym, camping and shorter trips. The ability to wear it like a sling is super convenient when there are no, or only small or dirty countertops - great design insight 👍 The material is robust, it can withstand chalk and has a appropriate amount of organisation inside. I pop my toothbrush and toothpaste into the exterior pocket because the interior sleeve is just a bit too finicky for my tastes.
Everything in the title : it has the same robustness than the other tech bags, it can carry a relatively big volume of toiletry etc, and it does attach efficiently on the posterior face of the Prvke
