Mizuno Running Men's Breath Thermo 1/2 Zip Top

I bought this in the midst of a horrific winter, where I decided I needed to run outside more. I'm not sure if it really works. It obviously isn't windproof, so still plan on using at least a windbreaker.HOWEVER, having worn this outside, I'm really not sure that it heats up - or if it does, the effect is subtle enough that I felt cooler in this than just wearing a long-sleeve 'insulating' layer with a t-shirt.

Comfortable and easy to run in but was a larger fit than expected. The arms were too long for me

Another top product from Mizuno, very breathable and doesn't restrict your running. It wicks up the sweat like you wouldn't believe.

Excellent It's all I expected size color quality it's worth every dime !

size is more medium than xx-large.

Logos for cool runs. Sizing is a smaller than other brands
