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.

Helped my get rid of some synthetic gym shirts
As others have pointed out, this T is a very thin material. Just what I wanted for gym wear. Being on the large side of large, I also appreciate the roomy cut. To improve it, make the neck opening a bit smaller and the sleeves a bit longer. For everyday wear or layering I would choose a shirt made of thicker material.
Nice shirt fit is a little off
100% cotton is thin but nice, like the colors too. Fit is kinda weird, ordered MT and the torso is a little longer as it should be but the sleeves are not proportionally longer, don't know if this is exclusive to the Tall sizes but it's a little odd, not sure I'd buy again. A long sleeve version could be nice too.
Best cotton T-shirt!
Absolutely awesome, comfortable t-shirt. So hard to find real cotton these days and there's nothing like it for a nice weather day. Same thickness as a Hanes undershirt. Love it. Just the right weight. Color is great, just wish there were more of them. I wear an L and it fits perfectly. REI, please sell more 100% cotton t-shirts without logos and graphics on them. I don't want to be a walking billboard all the time. Thank you!
Trailsmith Trusty T
As others have stated it is a very thin and has a slightly odd fit. I’m 5’11” 205 lbs usually fit well in an XL. Here the sleeves are much shorter than shown in the photo with the model and the neck opening is bigger. Bought on sale so will keep. The soft cotton will make a good polishing cloth.
Solid Basic T
These T’s start off soft with a good fit and a good clean Line. The cotton is thick but not heavy and the sewing, at least so far, shows all the signs of holding up for the long haul. This is my basic day in day out work t now.
Good, not great, shirt
Nice shirt. Well made, decent sized pocket. Very soft cotton, but very thin and seems unlikely to last long. For the price, I was expecting something a little thicker and more durable. We will see.
Probably ok if it had any length to it, materials
Don’t buy this size, xxxl if you think it’ll add length to the xxl. Its just not any longer.
wear it all the time
high quality shirt...super comfortable
