When you're gearing up for a cold weather outing why should your bra be the weak link in your otherwise meticulously planned, technical clothing? Our Zeroweight Medium sports bra features our Zeroweight insulation that boasts up to 30% increased breathability and lighter weight than other insulations. With its new insulation system, Zeroweight offers the best warmth-to-weight ratio. Cross and adjustable straps along with an adjustable hook-and-eye closure allow you to dial in the perfect fit. Add this bra into your technical clothing line-up and be confident that you've got the best coverage from top to bottom.
