Woolrich teamed up with Minnesota's Frost River to produce the versatile Summit Pack. Handcrafted in the USA, this backpack is just the right size for carrying an extra layer, a laptop or books in the field or through busy airports. Sturdy, water-resistant waxed cotton canvas bottom paired with a rugged Woolrich-made wool (Black) or wool blend (Red) upper. This bag is lined with water-repellent oxford cloth nylon. Hand-cut leather carry straps and closure with solid brass rivets and hardware. Under the top flap is a roomy zip closure storage pocket that organizes smaller essentials like your keys and wallet. A drawstring closure secures the main compartment. Adjustable shoulder straps are padded for comfort. Available in The Original Buffalo Check™ plaid, created by Woolrich in 1850.
