The Don. Ah yes, its packs like these that make All-Mountain Freeride biking more enjoyable on longer days. The Don packs just about everything you could need for an entire day in the mountains, while keeping all your goods organized and secure. This pack contains storage for a Full-Face Helmet, Body Armor, and a 3 liter hydration reservoir. The inside of the pack is littered with pockets that keep a tire pump, shock pump, CO2 cartridges, tubes and tools neatly organized, as well as houses a fleece-lined pocket that stores goggles or sunglasses safely. If you incorporate the CamelBak Flow Meter, you can keep tabs on how much water you are consuming, and will know when its time to start conserving the last bits to get you through the day. Between these two great products from CamelBak, you can enjoy longer and more sustained rides through the backcountry.
