Comfort & Effectiveness:
Under Armour’s Flats Guide Shirt has two built in vents providing comfortable, cross ventilation without sacrificing the aforementioned contemporary styling. This is accomplished by concealing the vents within the seams on either side of the shirt instead of going with one large flap across the back.
And an inside mesh for next to skin comfort.
The synthetic fabric of the shirt is designed to provide a UPF30 level of protection from the sun as well as wick moisture away from your body. Wicking fabrics are quite common in today’s day and age. Much in the way that
Gore-Tex is the name brand fabric that comes to mind when looking for wind and rain protection, coolmax is a name brand fabric that popularized moisture wicking performance in everything from socks to technical outerwear. The material in this shirt is not coolmax but behaves in the same way moving moisture away from your skin to keep you warm when it is cool, and cool when it is warm.

UPF (Ultraviolet Protection Factor) is a relatively new rating system designed to communicate the effective ability of a fabric to absorb harmful UVA and UVB rays from the sun. UVB rays are strongest during the summer months when the sun is stronger, but UVA rays are present year around and potentially more dangerous to your health than UVB rays. A UPF rating of 30 indicates the respective fabric blocks somewhere between ninety six to ninety seven point four percent (96% - 97.4%) of the sun’s harmful UV rays. The current, highest UPF rating is 40 – 50 indicating protection from ninety seven point five to ninety eight percent (97.5% - 98%) of the sun’s UV rays.
For those super hot days, you can roll up your sleeves and have them held in place with this internal strap, but of course, then you forego the UV protection on your arms.
So how does this all translate to real world comfort and protection out on the water? On one of the very first field tests out on the water, I had taken off my Under Armour Shirt in favor of my TackleTour jersey to prepare for a photo-opportunity. After photos were taken and the fish released back into the water, I resumed fishing for a bit without putting the Flats Guide shirt back on. The sun was high and it was getting quite warm. The thought occurred to me I had better put some sunblock on and then I remembered the shirt. In true TT testing fashion, I picked up my shirt off the deck of the boat and put it back on – over my TT jersey.
The Under Armour Flats Guide shirt not only looks good...
What I immediately noticed was how much cooler I felt with the Under Armour Flats Guide shirt back on and I was quite surprised. Since I had my TT jersey on underneath, this was no wicking effect I was experiencing with this shirt, but rather, it was the effect of the UPF protective fabric. Had I put regular cotton shirt on over my jersey, I may have received a small degree of protection from the sun simply for having covered my skin, but there’s no doubt in my mind I’d have felt warmer, not cooler.
... it's comfortable to wear while fishing.
In fact, a common white t-shirt only provides a UPF factor of seven (7). If you want UPF protection from regular fabrics, color is your best bet and can increase a t-shirt’s UPF rating to maybe ten (10). Your actual best bet is to put on something thick and dark like a denim jacket that will offer one hundred percent (100%) protection from the sun, but that’s hardly something you want to be wearing on a hot summer day.
Extremely breathable and lightweight feeling
