I bought one just to protect strings when busting through brush. When I received it I was disappointed it wasn't long enough for my prime rival. I had a friend cut it in half and add about 3 inches of material and it is still a tight fit. I never use the sight or fletching cover, I probably would use the fletching cover if it was long enough to cover the entire arrow wraps (also bright color).
Bad Medicine Archery was making one that was waterproof and had a sling strap (would be a nice feature on the Kuiu but I guess that's not what it's made for) I've never handled one but heard good about them.
Note : I sometimes wonder if the Velcro on the inside does more damage to my strings than it protects it from, when I'm trying to take it off in a hurry!?
