Filson's ultra-lightweight shirt packs easily for travel and is versatile enough to wear anywhere. It's made of breathable cotton that's been pre-washed to reduce shrinkage. The pleated back provides mobility through the shoulders, so you can work, flex, and stretch in it. Adjustable cuffs and a hem long enough to tuck in provide breathable protection. Double-needle construction adds durability to this versatile shirt. The dual expandable chest pockets are built for storage when needed.
