User Review: CamelBak UnBottle
Price Paid: $14
This thing rocks! It keeps liquids cool for hours, but also keeps it from freezing in the dead of winter. Sat in my pack (with insulated tube wrap) all night with temps in the teens and never froze. The lash points are great for attaching to the outside of a pack, though most packs worth their salt have internal sleeves these days.
My son uses this for hydration on hot days of baseball: he just buckles it to the dugout fence and it stays up off the spit and seed-ladened floor. The 100 oz. are great for my all-day trail rides around Vail Lake, and the durability saved my spine when I endo'd over the handlebars, landing on my back (Unbottle in the pack's sleeve made for a fortunate cushion.
Easy to clean. In fact, cleaning when only using water each day is not a frequent chore. Get one!
