Quality Baselayer

I love this. Perfect for an early morning run.

Extremely Comfortable

My new favourite piece of running gear, so much so that I have worn it more after a run to relax in. When used for running it is extremely comfortable, well fitting and warm. Love it

Cosy and good features

Nice bobbly bits and bits on sleeves to tuck your hands in on a chilly parkrun morning

Running Top

Needed a new undertop, having previously bought underwear I decided to purchase a top. I found it very comfortable and warm, really nice bit of kit

Great Quality Base Layer

Very happy with this product - the fit, the performance and style.
