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.

Great wicking capability

I wore this shirt for the first time o. A 20 mile hile in 85F temp blue skies. I left the sleeves down to cover my arms and this was a really great shirt. It wicked the moisture great and as the slight breeze blew it evaporated the moisture making me feel cool. This is a really nice shirt to wear even on warm days.

Good apparel for sleeping bag

Nice breathable, comfortable garments but they forgot to add 2" knit cuffs on the pants. I bought a large tall and it fits well.

Fit is true to size, and a nice soft material. Wore on a recent cold weather thru-hike for 6 days continuiously. A little smelly at the end of the week, but still kept me warm, and breathed well.

Nice quality and fit
6 months ago
Great light to mid base layer. Fits well and has good construction. I’m 6’3” 205 lbs and the Large/tall fits me well. I have long arms but don’t have a big midsection, so I’m glad the cut isn’t too baggy. It breathes well, but I can’t comment on how it responds in activities outside of jogging yet, but I assume it would work just as well for hiking, cycling, or snow sports.

Quick drying extra warmth

This is a surprisingly warm layer for what it is. Since it dries quick, I like to use it as a little extra insulation on cold hikes when I'm active, and keep my other insulation layers dry.

This is just what I needed. It’s a quality and light weight quarter zip that I can where just about anywhere. I especially want to wear it during hot weather to block sunlight.
