Disclaimer for this product. This tank was part of the Ogio KTM Team Dakar Hydroback. Perhaps the most expensive hydropack. The problem is the little blue plastic caps that close the bladder. They are extremely fragile. If the seam isn't perfectly aligned, the blue plastic fasteners will break immediately. Mine broke on the first use of the packaging and the replacement parts broke on the third use. Ogio won't replace the blue strands, just the entire bubble, and that's taken months. All they had to do was send me a $0.10 piece. Twice he let me down and therefore immediately in the garbage.
