Captiv8 Supply: Unlike bottles, thermoses, or the old school ‘bota bag’, these canteens roll and fold up when not in use. They’re perfect for day tripping, camping, backpacking, biking, beachcombing, and just plain relaxing. Tuck it away until your next adventure! Each one features a heavy weight cotton canvas cover with a BPA free, leak proof, and airtight liner that can hold 4 oz, 16 oz., or 25 oz. The food grade liner does not impart any ‘flavors’ to your beverage. They come with a push pull spout, an aluminum carabiner and a hang tag. Your 1-color or full-color logo can be printed on the front with the tote+able USA logo printed on the back.
