When you're choosing a baselayer for winter training runs, excellent thermal performance and optimal moisture management are vital – this WARM series crew neck delivers on both counts. Created with soft performance polyester that dries quickly, locks in body warmth and wicks away moisture, this thermal first layer top features a brushed fabric inner that further enhances insulation and breathability – perfect for high-intensity workouts in sub-zero temperatures. Effect by Odlo fibres, which are treated with silver, provide an antibacterial effect that neutralises body odours, keeping you feeling fresh no matter how hard you're working. Flat-stitched seams eliminate chafing to ensure maximum next-to-skin comfort, while a longer cut at the back ensures drafts don't find their way during your warm-up stretches. All in all, this is a great choice of performance underwear for maintaining a warm and dry personal climate, even when you're pushing yourself to the limit.
