Our top of the range aero calf sleeves for triathletes. An unrivalled piece of aero technology designed for the world's best athletes, the Neo Guards feature the same fabrics and double layer technology as used in our top of the range Neo TT suits.

These calf guards are based on our Neo Aero Socks, where we found a 10.2W saving at 40kph vs our previous generation. The use of new, lighter fabrics aids breathability for improved comfort in hotter race conditions.

The absence of material covering the foot also means these aero guards are legal to wear under your wetsuit during the swim, saving you even more time in T1 as it's one less thing to put on before your bike leg.
