Roosters ‘hottest’ base layer in the range, these thermal leggings use a combination of two of our most popular fabrics for the utmost comfort and thermal performance. The main ‘heat’ boosting properties derive from its 0.5mm titanium lined neoprene used at the upper front legs, seat and back of legs. This fabric is a clever material that works with your body to regulate your temperature, where the titanium lining reflects heat from your body back onto your body, rather than letting it escape through the fabric. Through combining this ‘Hot’ fabric with our soft and stretchy Polypro™ on panels where you want the maximum movement and breathability, crotch/gusset, waistband and upper sides, these leggings will give unrestricted performance. Wear them next to your skin for the best performance. A great heat boost for underneath your other layers on colder days or on its' own for very active sports.  Features:•    Titanium lined 0.5mm ‘Hot’ neoprene at upper front legs, seat and back of legs•    Polypro fabric at crotch/gusset, waistband and upper sides•    High fit contoured elasticated waistband•    Double lined Polypro panel at crotch •    4 way stretchMaterials:•    Titanium lined 0.5mm neoprene•    Polypro
