I wear these shirts all

I wear these shirts all summer. I even take them on vacation as they are perfect for a hike or day on the beach. Perfect fit and durable even as a thin layer with all the sun protection you could hope to have.

B1 long sleeve tee

5 stars! These shirts are the right weight for layering. They are very comfortable and they breathe. My work requires a lot of lifting, moving and walking. Once I really get started I get hot and sweaty, but the B1 long sleeve tee keeps my temperature just right without overheating or feeling like I’ll pass out! Really, thanks for designing the perfect shirt for workers! I wear long sleeves at work, even in the summer and these are light enough to make the warmer months a breeze!

Very comfortable, feels extremely light but can really generate warmth as an under layer.

This shirt has a very light silky feel, although it doesnt seem to "stick" to me. When used as an under layer outside in the cold, it is surprisingly warm. I am very pleased with the performance and look of this long sleeve truewerk Tee shirt
