The RBK Lab Thermal Quarter Zip Top arrives in Breakout Blue and Black, built for training sessions when the temperature drops and a base layer alone won't cut it. It is the thermal training layer that earns its place across the whole cold-weather rotation. Cut-and-sew contrast fabric panels run through the construction, delivering structure and a sharp two-tone finish. A kangaroo pocket sits at the front for easy-access storage, and a bungee cord hem channel lets you adjust the fit at the waist. Contrast zip binding finishes the collar with a precise edge. The relaxed build sits well over a base layer on colder days or worn solo when conditions are mild. Pair with fitted training tights and a clean training shoe to anchor the look.
