    1. One Fastpack to Rule Them All

      For multi-activity days, this is my go-to pack! Legitimately runnable (it's just a little larger than the PB Adventure vest) the Fastpack 20 is also a great, comfortable pack for hiking, mountain biking, climbing, coffee shop haunting - you name it!

      I absolutely love the back two outside power mesh pockets: good to put additional food and water, clothes, and perfect for a second pair of shoes. Bike commuting to work? Pop your work shoes in these pockets and swap your shoes right after you lock your bike up. The pack can hold additional volume to grab some grub from the store when riding home.

      The orange is a great, bold color. The left cellphone pocket holds my large cellphone with equally monstrous cellphone protector just fine.

      As well as comfortable, this pack is made to LAST, being one of the most bulletproof UD product I've ever had the pleasure of using.
