There are very few reviews of this product. The Gewa Rucksack fits my oblong Air case like a glove. The straps are extremely comfortable and the side pocket fits a folding stand. The front pocket holds a decent amount of music.

HOWEVER, if I’m not out on a gig or some longer term traveling, the back pack is a bit too much. You have to unlatch the backpack to access your instrument and it is kind of a hassle. For touring musicians, this is a great addition to an already great violin case!!!

Nice in concept, bad execution. The backpack barely fits around my Gewa Air, and it's really hard to buckle it in. The straps are also made of a material that really chafes my shoulders, so if any skin is exposed it hurts to carry it.
