This beautiful and unique design bottle water holder/carrier is adjustable and stretchy. It is suitable for most of the bottle . The strap has a button in case you want to adjust the length or shoulder wear . Hands free while walking , hiking , camping , hunting or any outdoor activities. When you are outdoor , always take water with you , keep it hanging on your shoulder or cross body. The Length of the bottle water strap is 20" but it is stretchy and adjustable. All my products are handmade , crochet with love and care in a smoke free and pet free environment. I use cotton and acrylic yarns.
