Description of Timbuk2 Commute Pack The Commute Pack is durable, practical, and really really good looking. It has a soft place for your laptop (fits 15" laptops) to rest and comfy straps to keep you connected. The grab straps on the top and center of the bag make this pack far more than average knapsack. The Grown Collection is Timbuk's vision to moving towards utilizing parts and materials that are better for the environment and less harmful to the folks who make them. Last year they took a big step by eliminating PVC from their entire line. These bags are another step in the right direction. On some of the key styles you’ll find the same fabric texture both inside and out. The bag maintains water resistance and durability without sacrificing style. Self fabric trim adds to the finished look. Fabric is made up of 66% hemp, 33% PET, and 1% mojo.
