Review on OYATON Water Bottle Holder With Adjustable Shoulder Strap, Portable Bottle Carrier Sling Folds Into Pouch For Easy Storage, Perfect For Walking Travel Hiking Plastic Or Stainless Steel Water Bottle by Michael Rosario

I was looking for a large canteen for hiking and didn't find an option. Instead I found these option, which is actually better in many ways.You can put in nearly any bottle to work as a canteen. I had been putting my bottles in a side sleeve of a backpack, which was always hard to grab since I drink so frequently when hiking.I've only used 16oz bottles and a 750ml (25oz), but clearly larger and smaller would fit. When hiking I can just exchange the bottles once or twice and have my water accessible.I haven't used it enough to know extreme durability, but it appears very durable--I can't imagine it wearing out soon or even extended use. Even the elastics seem strong.
