‘Frost River’ specialises in outdoor adventure packs: with no unnecessary frills, this stripped-back bag looks as rugged and tough as an American woodsman. The Nessmuk Pack has been designed as a replica of writer George Washington Sears’ old Maine Guide pack, all the way back in the 1880’s. With Frost River believing you can’t improve on perfection, the Nessmuk measures up 16"h x 12"w x 5.5"d, plus pockets and expansion from 1056 c.i. (Actual) to 1900 c.i. (approx.).
