Great fitting, amazing fabric

I love the fabric, and the fitting is amazing, love how it sits on my chest. Sleeves can be rolled up perfectly to rest wherever you want. The only thing I find a bit off is the stitching near the shoulders to collar area.

Great shirt

Worn during recent cold snap, was very warm, all day. Washes well and drys very quickly.

I have bought a few items on line and they are all tight especially the sleeves on long sleeve tops. I am quite slight build.

Base Layer

Used for Archery and also cycling and makes a good base layer with great breathability on those long days cycling or standing in fields shooting.

Just what I needed

Needed some new baselayers as mine were faded so bought two of these in the sale and they are absolutely brilliant! Bought two more as spares and will be getting some more for the winter.

Why wear a base layer?

The base layer, also known as the inner layer, helps: . absorb perspiration and transfer it to the outside. Your skin stays dry and your body does not get cold . retain body heat; even more so when the product is close-fitting. . provide an additional barrier against bad weather. keep your soccer shirt dry, even when you're running hard.Playing with a base layer makes matches so much more comfortable. Once you've tried it, it's hard to go back.
