Warm base layer

Good product which was sized quite tight. The arm cuffs are a nice feature and integrate with my present top layers which do not feature this. However if one had a jacket or top layer also with cuffs then it might become a bit bulky at the wrist. Otherwise this does what it says on the packet!

Best Base Layer at this price

I recently competed in an SAS test march in the Brecon Beacons, called the Fan Dance. There was snow, sleet, rain and 45 mph winds. Bought this top as a last minute addition to my kit and decided to wear it in the day. It was brilliant, Warm, when wet and did the job perfectly. Yes you can buy better but you will pay upwards of £60. This is a great top and well worth it. buy it!!

Excellent Product

For what I paid,I couldn't of got anything better

Blocks cold air

Wool has changed considerably over the past several years. This natural material is warm, soft, breathable, stretchy, and odor-free. It is a fabric perfect for skiing or snowboarding. With a strong insulating power, the 20% wool provides natural warmth. Combining it with polyester guarantees good comfort throughout your activity.

Wicking away of perspiration

You are more likely to sweat on the ski slopes and when exercising. In order to keep you dry, the breathable fabric lets out perspiration produced by the body. A collar equipped with a mechanical zip helps modulate the heat of your undergarment. The use of a non-brushed and more stretchable component under the arms improves the management of perspiration.

Dress well on the ski slopes

In order to stay warm and dry, it is important to check the coherence of your equipment. We recommend applying the 3-layer rule. The principle is quite simple: overlay three textile layers each having a particular function. Above your skiing base layer, the second layer should produce and retain warmth, finally, finish with a ski jacket which will protect you from the weather. All these layers should be breathable in order to
