The Filson Lightweight Alaskan Guide Shirt is a three-season workhorse, built for comfort, durability, and practical functionality in the field, on the job, or around the ranch. It’s a lighter-weight variation of Filson’s iconic Alaskan Guide Shirt that’s been a trusted favorite of ranchers, guides, and bush pilots for decades.
Made from lighter-weight 4-oz brushed cotton twill, the fabric is soft yet durable. The relaxed fit and rear-shoulder box pleat allow non-binding ease of motion and excellent air circulation. Gusseted button-flap chest pockets keep small valuables handy and secure, and custom Filson-logo buttons on the front and cuffs are made from chip-resistant polyester for years of use.
