Nice multi-season shirt!
Great versatile shirt. Hiked with vest over it in cool winter temps. Comfy and stretches to accommodate movement. Thumb straps on sleeves a nice feature. Looking forward to year-round use with ShadeFactor50 sun protection.
Great shirt for cooler days
Fits to size, nice wicking material and it dries quick after workout. I would definitely recommend this shirt. Thumb holes are good for some, but not something I look for in a shirt. I’ve worn this shirt for several workout and my last one was a 4 mile hike.
Luxurious Feeling Shade T-Shirt
I have worn this long sleeved t-shirt for a couple of weeks as a base layer because of the cold weather, but today was warm enough to wear by itself. The shirt is made of polyester and spandex and feels really great against the skin. It fits loose on the body allowing air to flow and not get too hot. The thumb grips are an interesting feature to keep the sleeve down. I really like the olive ridge heather color as well. This makes a sturdy base layer or outer t-shirt to keep off the sun and is soft on the skin. I want to wear this every day.
Perfect first layer.
Tested this shirt the day after purchase and it performed wonderfully. Started the hike with this shirt as first layer, with a lightweight REI fleece as over layer. Temp was 50F, and was neither cold nor too warm with this combination. As the temps climbed (as did we), removed the fleece and wore only this shirt. It wicked away sweat, and remained pretty much dry the whole 4.5 mile hike, then dried quickly at hike’s end. SPF rating for this shirt is 50+, and provided ample protection from the very bright sun that day. At approx 1/2 the price of other brands, this is a great deal for the money.
Lightweight And Soft
The product description is spot on. I do not typically shop for long sleeves unless as part of a base layer. I own a few "performance" type synthetic long sleeves but never wear them because they are not comfortable and have a plastic feel and shiny look that I am not a fan of. This shirt is none of those things, very light, very comfortable and fits great. The thumb loops are interesting and like the description says "discreet".
Super comfortable
This shirt is really comfortable. It washes up well and holds its form. I have worn it in hot and cold weather and it seems to adjust well because I stayed cool in the heat and warm in the cold. It's almost like there is a 5 or 10 degrees buffer with it. I have gone on hikes with it and it wicks sweat well. I also feel like I could wear it out to dinner and look dressed up. I got a medium size and I'm normally between medium and large, but the medium is plenty big for me but fits well.
