The Battlepack 45L is our mid to large sized backpack. Works great for all activities and travel (meets airline carry on requirements). It has plenty of room to carry all of your gear with various internal and external pockets to keep things in order including a padded compartment which fits up to a 17" laptop. Made utilizing a hemp/organic cotton canvas blend which is naturally anti-microbial, breathable, durable, and environmentally friendly.
Also if you are fan of our friend Joe Rogan, consider buying the JRE branded version at Higher Primate
