3.3L holster with secure vertical capacity A large capacity holster with vertical capacity that can easily fit a long wallet or 500ml plastic bottle. Grimm is highly convenient and can be opened/closed with a single push, including a hold cord that compresses the contents according to the content, and holds the cap so that it does not flap when it tends to scatter while driving, greatly reducing the risk of loss. Equipped with a locking carabiner as standard equipment, a large carabiner loop that allows you to hang the carabiner with one hand, and a glove holder, all of which are useful when getting on and after getting off the bike. The inside is made of cool gray fabric that makes it easy to see the contents, and the main space is equipped with a slit pocket for small items and a triangular gusset to prevent items from falling out when opened wide. The main space has the same thickness from the entrance to the bottom, allowing you to store your belongings without wasting anything. Each function is designed to be ambidextrous as much as possible, so you can wear it on either your right or left foot, depending on your preference.
