The base layer that adapts to your needs
The Keepdry 500 helps retain your body heat as you exercise while wicking away perspiration. This means you stay warm without ending up with your shirt soaking wet at the end of the match. The fact that it adapts to your body temperature means you get just the right level of warmth to suit you. It's a slim-fit base layer that offers you natural freedom of movement.
There are a number of reasons why you should wear a base layer. First of all, you won't get as cold, which is no bad thing! But not shivering while out on the pitch can also have other unexpected benefits. One is that you can focus on your game and nothing else. You won't be tempted to overdo things during the warm-up or at the start of the match to keep warm. If you take pride in your appearance, you can't deny that a good base layer looks pretty stylish. If pretty much every pro wears one during the winter, then it must be for a good reason.
My advice to you is to get two. When you're training several times a week, it can be a pain to have to wash your one and only base layer after every session.
