Inner layer shirt

Great fit and really like how this blocks that wind on your chest. Able to wear less gear now thanks to this wind blocker. Living in Seattle, this is just enough to stay comfortable in our cooler/ wet climate and really like the open mesh on the back. I will be grabbing another one of these soon.

I got an XL that fit pretty true to size,I don't like tight fit, worked for me.

I was already familiar with this product from an earlier purchase.Description and Selection of M results in a US size S not M which was a surprise. The M sizing is indicated as Euro and S sizing is indicated as US on the product label.Fortunately it fits snugly but OK, the same as the previously purchased product. - The same manufacturer's comparable T shirt style design is more predictably sized - US and Euro are same indication for the M size.

This vest does a great job of blocking cold air from digging through my cycling shirt and sapping my energy and motivation to be out on cooler days. It is thin and easy to stash in a cycling jersey pocket in case the weather changes. I’m currently 6 feet, 210lbs, 34 waistline. The large fits me well.

I've worn this most every day running in cool, windy conditions. I wear it over a long sleeve technical shirt. It's a "must have" for me. I often pair it with this item I also purchased: Under Armour Men's Run Gore-Tex Windstopper long sleeve shirt. I swear by Gore Windstopper. I also have a beanie made with Windstopper. Excellent. Great stuff

Love it.i ride 2 work everyday on my motorcycle and it work great stops the wind at 120 noproblem.

If it's windy, a bit cold or rain is in the forecast this garment under your jersey will make your ride much more comfortable.

This wind blocking base layer worked flawlessly in windy cold conditions.
