This is a never before worn Filson shirt. From their website: A lighter variation of our classic, most-trusted outdoors shirt. The Lightweight Alaskan Guide Shirt is a workhorse made for three-season comfort, durability and performance in the field, on the job or just kicking around the ranch. It’s a lighter-weight variation of our iconic Alaskan Guide Shirt that’s been a go-to, trusted favorite of ranchers, guides and bush pilots since 1996. Our original Alaskan Guide Shirt has proven itself a favorite time and again from Alaska to Maine to the Rockies. When our customers asked for a version for warmer conditions, we listened. The result, made with 6-oz. cotton twill, exceeds expectations for versatility, comfort and universal utility. The cotton is soft, yet durable. The relaxed fit and rear-shoulder box pleat allows non-binding ease of motion, while allowing plenty of air circulation. Expandable, gusseted chest pockets with button-close flaps keep small valuables handy and secure. The custom buttons on the front closure and adjustable cuffs are chip-resistant for years of durability.
