I love this Camelbak the most out of the 3 I have. I use it when riding dirt bikes or racing in the woods. Fits over my chest protector and holds my essential tools, fix-a-flat, and a spare tire tube and Ive had no issues with it. When its full I can easily go nearly a day with it, it seems like you never run out of water! I definitely Recommend this product to any outdoor enthusiast!
