Review: Best running buy of the year so far, helps get you out of the door in the cold! - Fits beautifully, no chaffing, nice and cosy even during the very chilly English weather during January February and March. Like the boxers and short sleeved undershirt I bought at the same time it wicks moisture very effectively and does not leave you feeling wet even when on a recovery section. Cant recommend them highly enough. The long sleeve undershirt has been my fave wear during the very cold weather, along with the boxers it has served extremely well and made taking that first stop out of the door much easier on some cold days! Not cheap but exactly right to do the job I needed doing, as a generally very moist runner who had previously felt the chill if I stopped or slowed these keep me warm even when they are wicking hard! Merino underarmour were recommended on twitter #runchat by other runners to my specific problem of being a runner who got very very wet on runs and really needed something to help make running in the cold months easier, so that I wasnt heating up running then cooling very quickly, being wet, when recovering. these make winter running much more comfy! I bought a spare short sleeved undershirt and boxers at the same time (having been given another short sleeve undershirt shirt for Christmas) and they have done superb service during the winter. I can see that in early Autumn the short sleeves will come into thier own. Its now (late March) getting a little too warm for the undershirts but the boxers are still perfect!
Review: Loved it - Fantastic.

Fantastic.

### ⭐⭐⭐⭐⭐ This product is warm, breathes well and is odourless after hours of physical exercise.
*by S***L on 13 February 2025*

I am a competitive coastal rower and an avid hill walker in North Wales, UK. I wear my long sleeve skin tight Merino as a base layer under a Buffalo top and it the perfect combination for night time rowing and hill walking. I naturally sweat a lot doing the slightest of exercise, and my Marino breathes through to my Buffalo which wicks the sweat away. Despite their price I have now got two long sleeve and two short sleeve. For sheer comfort I couldn't be happier with the performance of this product, and well worth the price.
