Whitman Knapsack (Sand)

Classics are classics for a reason. And this minimalist, modern ode to the venerable Rucksack venerates it with style.

The impeccably constructed Whitman features two interior pockets -- each capable of handling 15” laptops -- and two exterior side pockets for your mobile phone, keys and other go-to items. Adjustable straps and a buckle front closure keep things snug and secure.

Handcrafted from rugged, water-resistant canvas and snazzy chocolate Brown leather accents, the result is an accessory that is both uniquely great looking and tough enough to withstand years of carefree daily use.
