Reviews
Great Shirt for Summer
"I like this shirt for summer. Long sleeve protects the arms while at the same time, it's not hot, like a cotton shirt would be. The color offerings are frustrating. I would order different colors but some colors have "Truewerk" in bold in the front, while others do not, plain. I prefer not to have the big "Truwerk" lettering in the front, limiting color choices."
— Stephen S. (5/5)
Farming Workshirts Par Excellence
"I've been buying the Truewerk longsleeve workshirt technology Tee for several years on our vineyard farm. These shirts get worn everyday as a sun screen and perspiration releasing layer in summer and winter. Durablility is very good and my oldest Tee is about 3-4 years old. In comparison to similar REI and North Face technical Tees the Truewerk Tees don't fade from repeated sun exposure. Terrific product worth having for daily outdoor work."
— Gary S. (5/5)
B1 long sleeve tee
"I love both the long sleeve and short sleeve tee shirts from your company. I find cotton long sleeve shirts to heavy. Espically during the summer heat and humidity. These shirts are comfy and light weight enough for year round wear. Thanks"
— Samuel 1. (5/5)
My son is in the
"My son is in the heat and sun all day on his job. He is fair skinned, so he really needed relief from the sun. He says he stayed cool through the day. We will definitely be buying more shirts in the future."
— Deane N. (5/5)
The Ultimate Mowing Companion: Cool Comfort in the Heat
"I am incredibly impressed with the Truewerk B1 long sleeve shirt. I’ve been using it specifically for mowing my lawn, and it has completely changed how I handle yard work in the heat. Despite it being a long sleeve shirt, I never once felt like I was overheating. The fabric is exceptionally breathable and manages moisture perfectly, keeping me cool and comfortable even while pushing the mower under the sun. It provides excellent coverage without the heavy, stifling feel you'd expect from other long sleeve gear. If you’re looking for high-performance apparel for outdoor chores, this is a top-tier choice. Highly recommended!"
— LAMAR S. (5/5)
I’ll be ordering more!
"Love you gay it is durable and it helps to keep me cool and protected from the sun. It functions as described and it keeps me comfortable in the summer sun. Just like all the Truewerk products it’s built great."
— Derek B. (5/5)
Great for outdoor work
"I bought these shirts for my husband for him to wear while doing yard work. We live in an area that can get very hot and humid so having sweat-wicking and breathable material was a must. The SPF resistance is a nice bonus, and the quality of the garments seems high! We are very pleased with the item(s) so far."
— Camilla B. (5/5)
Great shirt
"This shirt is really breathable and really light especially during the summer especially with this warmth, I live in texas and it gets pretty humid and this wearing this short makes it feel like it isn’t. As for the resistance it’s pretty great, I hit a steel corner with the shirt and nothing happened, that should tell you enough on how resistant it is."
— Emiliano L. (5/5)
extraordinary comfortable shirts
"as a roofer i’m always looking for the best cooling/comfortable shirt and i believe these take home the price hands down all day …i have told my friends about how good they are and im currently trying to change my workwear over to this amazing brand simply the best"
— Andres G. (5/5)
Best Work Shirt
"This shirt fits perfectly, keeps me cool and protects from the sun,scratches, bugs and poison ivy."
— Todd d. (5/5)
Q&A
What are the length of the torso and sleeves on the B1 Men’s fit? The “see if it fits” Infograph is cool and all but I’m 6’4” and built like a gorilla, I’m worried that the shirts will be too short and can’t find any actual dimensions.
The B1 short sleeve might be a bit small for your build.
Does the material shrink?
No, they shouldn't shirk.
Does Truewerk make a 100% cotton product? I'm an electrician and cotton is a requirement.
No, we do not make anything 100% cotton.
What is the material?
100% Polyester!
orange color when will it be restocked?
Not going to be restocked until the fall!
