Amazing colors!
Love the shirt. Material is soft and breathable. Can’t wait to wear it in Costa Rica in a few weeks!

A must have for the adventurer!
I have traveled to Costa Rica for nature photography for the last 5 years. Whether I am deep in the jungle or near the coasts, I need gear that won’t let me down. I do volunteer prairie restoration work in the Midwest throughout the year. The sun is brutal and unforgiving in the summer. I have purchased five shirts from Seatec. These shirts have become part of my “go-to” gear for my adventures in nature. The high tech quality of the shirts helps me to stay cool and dry even in the harshest conditions. The design and colors are spectacular. They are soft and comfortable. I get compliments when I wear them. These shirts are second to none! I demand a lot from my outdoor gear. I was not disappointed and I recommend these shirts without hesitation!

So Cool
I’ve now purchased 7 shirts. Gifts for my husband and son and step dad. They all loved them. I love the awesome colors.


Wore the **** out of this one already.
Love the light weight hoodie, it wicks the sweat off, feels great in the breeze, and in the sun not actually as hot as I was expecting. I’m a 3x dude so summer time is tank tops but this is key when you gotta be out in it all day. I’m normally wearing all black so people prob think I’m off my rocker. Def a solid fit to a 3x size: it’s snug around the arms but loose in the chest to belly that allows the right amount of air in. Overall for my size I’d like to see the wrist area loosened up but other than that the fit is right on. I just bought a little bit darker one “kingfish” I believe. Little bit lowwer-key, when I’m by the campfire and don’t want to attract every bug in the tristate area.

Best of the Best
I personally wouldn’t buy any other brand, Awesome qualify, comfort and fit

Nearly perfection.
Super soft and breathable. Would have been 5 stars but the second shirt I ordered looked like it had spots on it where a highlighter or dye from a complete wrong color had left 3 spots. I would still recommend

Beautiful and excellent fit
Excellent fit and they look GREAT! I wore them for my fishing trip to Cabo, and they did the job!

Excellent product! They are my go to shirt/hooded shirt. Very soft and comfortable. Very attractive. I now have 6 of them. Highly recommended!

Xxl shirts
Too small gave them to son.

Great Purchase!
Absolutely love this hoodie, bought it for work because I work outside. Super soft, great fit, and looks great. Very happy with my purchase!

Great shirt
Awesome fit and great feel. Totally unique patterns. I bought 3

Fit
I am 6’ 3” 380 and the 4X fit perfect. Responsive with questions I had and quick shipping

These are the best shirts!
So comfortable, light, and tough! Literally the most comfortable shirts I've ever owned. And the designs kick *ss. Tough too, we have two large dogs who climb all over us and their nails will leave scratch marks on our skin with no rips or snags on the shirt at all. Impressive for sure. Customer service is great too. Responsive and always willing to help 10/10, would recommend.

Hooded Mahi
Comfort and color is great, I bought 3 other colors
