Forrestwrote a review of CamelBak Mule 12L Backpack on February 18, 2019
Familiarity: I've put it through the wringer
You will likely never wear out a Camelbak. In the last 20 years I have been mountain biking I have had two Camelbak's and the only reason I bought the second was because I was bored with my old one. The Mule is the perfect size for most mountain biking scenarios unless you are carrying all of the tools and gear for a sizeable group, the Mule can handle it.
I love the 100-ounce reservoir and prefer having too much water, or just underfilling the reservoir for shorter rides. I find that any time I am riding for more than 2 hours I reach for the Mule. Camelbak does a great job, the Mule is very comfortable and the internal organization is nice and thoughtful. I have had such amazing experiences with Camelbak that I cannot think of a reason to go with anything else for packs.
