Sizing Notes
Measurements are stated in inches unless otherwise indicated. Size chart values represent body measurements, not garment measurements.
SHORT: Some pants are available in short sizes, which generally means an inseam that is 2.5 inches shorter than regular sizes.
TALL: Some pants, shirts, jackets and parkas are available in tall sizes, which generally means an inseam that is 3 inches longer and a rise that is 1 inch longer, a shirt or jacket body that is 2 inches longer, a parka body that is 2.5 inches longer and sleeves that are 2.5 inches longer than regular sizes.
Capri or cropped pants have an intentionally shorter inseam—reference the technical specs instead of this chart.
Inseam is measured to the floor.

Very comfy t-shirt
Great fitting comfy t-shirt that washes well and keeps its shape
Great athletic shirt, sized too large.
This shirt is really nice, soft, great flex material but the Medium is way too big for me. The bottom goes all the way to my crotch, and the sleeves go to my elbows.
way too long, other wise a great fit
5' 9.5", 176 lbs, size Medium fit great but way too long. I hate it when a shirt comes down to the bottom of my crotch. Not sure why they make shirts so long.
Nice shirt, but a bit long
Overall, I like the material of the shirt, but it's a bit on the long side for a size medium. I returned the shirt, and got a Patagonia instead.
Extremely comfortable
I would have gone back and bought more if they had other colors. This shirt beat my expectations on comfort. It really is a great shirt.
Highly recommend
Great fit, comfy and cool color! Wore it hiking and it was great. Highly recommend
Very long
This T shirt is extremely long. It's definitely for tall guys. Had to return
