Great shirts I’ve bought before and will buy again.

5 stars out of 5 stars

Excellent under sweaters in cold weather and very comfortable on their own. Long-sleeved shirts are nice for work in an office setting. The price is reasonable and the quality is great.

Soft for sensitive skin

5 stars out of 5 stars

I love this shirt. I won one at A Memphis Americans Soccer game and loved it! I have very sensitive skin and it is very difficult for me to find something that feels good on my skin. I liked this so much that I ordered 2 with no logo on them. The colors run true to the pictures. They also make excellent sleep shirts since they are long. I may order a couple more. I can't say enough good things about them.

Sam - 05/19/23

Undershirt for me

5 stars out of 5 stars

I have several white golf shirts which require an undershirt. For golf and flexibility, this is ideal—cool, moisture wicking and quick drying.

Chels - 04/12/23

Perfect Uniform T

5 stars out of 5 stars

Much more cost-effective to buy our work shirts this way, we save hundreds! Great fit, wash up well, and are pretty durable.

nice light weight shirt - not sure about the 100% polyester

4 stars out of 5 stars

Nice comfortable lightweight shirt - but not yet sure how much I like the 100% polyester since it does not seem to "breath".

Shirts

5 stars out of 5 stars

These shirts are amazing, I’m in the military and the green shirts are by far the most comfortable shirts I’ve come across in my career. They do fit large, I typically wear an XL T-shirt but order L with this company.

Disappointed athlete - 09/05/21

Poor quality

1 stars out of 5 stars

Terrible quality. Looked fine new, but washed once per instructions and looks terrible. Permanently wrinkled, collar lost shape, body no longer blocks out evenly. Spend a little more and buy a good quality shirt.

Good product but a bit slow on delivery. Will order again.

Foss - 04/13/21

Unflattering fit

2 stars out of 5 stars

Sleeves too long and the shirt looks like it's made for people who have very large stomachs. The waist needs to be tapered and the sleeves need to be shortened.

Comfortable and Tough as Nails

Best tee-shirt in the world. I have seven Sport-Tek tee-shirts made with this fabric. Shipping was a little off. I never received a tracking number and did not know that Full Source had shipped until it arrived in my mailbox.

Great tech shirt

5 stars out of 5 stars

The Sport-Tek ST350 is a great technical shirt, very soft and smooth, mostly wrinkle-free, wicks well and dries quickly. I've had several of these shirts over the last few years and they hold up well too. Glad that Full Source carries it!

Wardrobe Staple

5 stars out of 5 stars

I've almost exclusively worn these T's the past five years or so after getting tired of overpaying for brand names. A few of these shirts can make up 90% of your warm weather wardrobe and at a fraction of the cost of the competition. They're long-lasting quality and will change your wardrobe forever.

Unbelievable value

This shirt features the same moisture-wicking technology as that used by the major manufacturers. The colors are vibrant and the workmanship is top notch. It's simply an amazing value.

Great shirt for a great price

5 stars out of 5 stars

I bought several of these for work and they're the most breathable shirt you can get. If you want a shirt that is great for warm weather or hot working conditions then this shirt is it. Will buy more in the future. 5/5.
