Poor workmanship

The shirts are light and comfortable, but after 1 wash, stitching is coming undone at the sleeve cuffs and the bottom hem.

These shirts are just as good (and probably the same) as Sport-Tek or Haines shirts sold on Amazon, but HALF the price! I bought five in different colors!

Great shirts

5 stars out of 5 stars

I love these shirts they’re very comfortable. I use them in the cold weather under my clothes at work. And I also use them for cycling when I’m riding in cool weather on my bike. This is the third time I’ve purchased these shirts and I will probably purchase more. I love all the colors that are available.

The quality of the material

4 stars out of 5 stars

We have used this brand in the past, I love the quality of the product. We use these as uniforms for our Dig Pink volleyball match, so the quality matters. They do not rip or shred, especially when a player is diving on the floor for the ball. They were also extremely reasonably priced.

Needed some new work shirts for my husband's business, so instead of buying them from a shirt business, I made them myself. Same quality of shirt we got from the place that made them before! And the price was right too!

Great shirt. Just what I wanted for fishing. Slightly slightly oversized. I could have gone with a small instead of medium.

Robert M - 04/25/22

Great all around shirts

5 stars out of 5 stars

These shirts are comfortable, cool, and long-lasting. I love how stretchy they are and they still maintain their shape quite well. I wear these as work shirts and also for personal use. I have some that are over two years old that I've worn to work and they still look good and are only slightly sun-faded. I will definitely buy more of these in the future. I almost forgot, they are definitely value priced as well.

My only problem is the sleeves are too long, but that's because I have short arms. These shirts are great and not too hot for play in the heat in Florida.

Good quality but haven't tried

5 stars out of 5 stars

These shirts are VERY nice and all of our guys liked trying them on. I just ordered some from a local tshirt shop but we haven't used them yet. I will update as they are worn. Full Source was easy to order from, and the shirts came in quick!

These are some very versatile long-sleeve shirts that have long-lasting quality similar to some vastly more expensive brands that I've tried before. Will be buying these again.

Epic Shirt

5 stars out of 5 stars

My boss at my old high rise window cleaning job bought these for his employees to combat the searing TX sun on your back then reflecting off mirror like glass for hours at a time. Now I use it as my mosquito shirt to cut the grass trust me these shirts can handle anything. I like it for running too because it fits me well with what I would call an aesthetic cut and You don’t feel it. This is a working mans shirt... and still comfortable enough to sleep in at night (clean). I had to sacrifice one of the 5 shirts I have to fashion a hasty face mask to enter a doctors appt..... I could not for the life of me, rip this shirt with my bare hands and I’ve got some meaty work hands on me... I sat in my car shredding it with a nail and at that moment i was impressed. My shirts have taken a beating and they are still just as bright as the day I got them. Maybe it’s because they’re neon orange. Anyway, highly recommended these shirts.

I usually avoid printing on polyester, but these held the ink perfectly and didn't melt in the dryer.

Was surprised on how quickly the shirts came in.

Mike - 02/07/20

EXCELLENT

5 stars out of 5 stars

I bought these shirts for a few reasons: I like the feel of the shirt, I like the long sleeves at the beach or in the sun and I like the price. I bought three shirts of different colors to wear casually or as an undershirt and I’m discovering that they are fantastic to work out in. So, great colors, multifunctional and at a great cost hits on all cylinders for me. I will definitely recommend these shirts.

These shirts are great. They hold up really well and the color lasts forever. I make shirts for divers. The dive pools and open water. Shirts have yet to fade even in the most chlorinated pools. They do wear a little big but well worth the price!

To layer or not to layer

4 stars out of 5 stars

Comfortable alone or under another shirt. Bought these for cool early mornings and warm/mild afternoons and evenings. Fits under my dri-fit polo style work shirt just fine. Strongly recommend buying a size down than your normal. I purchased larges but the 4 star rating is for the sleeves being too baggy and too long.
