The choice of the bag, and its size, is essential to ensure comfort during the performance. Basically there are three categories of bags: in synthetic fabric, in natural leather (usually sheep) and hybrid, which are composed of a layer of cowhide on the outside glued to a layer of waterproof synthetic fabric (Gore-Tex) on the inside. Personally, after years of experimentation, for various reasons we ended up preferring the hybrid bags, so in line with our philosophy they are the ones that we have chosen to offer permanently in our store. The presence of the zipper, which allows easy access inside the bag, is essential, allowing to handle the moisture control system, the drone valves when present and, why not even if it should never happen, to recover any reed fallen into the bag.
