Similar in design to a dry sack, the Vixen Optics Scope Carrier Bag provides you with a safe and convenient way to safely store and transport your delicate optical tube or tripod. Its strong and abrasion-resistant 420 Denier nylon exterior is made with waterproof seams and the top opens fully to give you complete access to the foam-lined interior. A roll-top closure for the opening and snap buckle make the whole bag waterproof when the top is properly rolled and closed. MOLLE-type ladder straps along the sides allow you to attach the bag to a backpack or other gear, and two cinch straps that wrap around the bag adjust in length from 9.5 to 25.25" (24.1-64.1cm) so you can take the slack out of the bag and stop your gear from moving, shifting, or otherwise getting knocked around while you're carrying it to your observation site.
