So darn lightweight,
yet so darn effective
"So darn lightweight, yet so darn effective." It’s the kind of feedback we hear time and time again from our customers — and it’s exactly what the UltraLite Running Series was built around.
Every piece in the range was designed with one clear priority: weightlessness. Lightweight enough to move with you, technical enough to perform, and versatile enough to handle the demands of everyday training.
From vibrant colours to functional design details, each garment was created to help athletes train without distraction. Whether you're running, cross-training, or using running as part of your sport, the UltraLite range is made to feel barely there — while still doing exactly what you need it to do.
The AC400 Windbreaker Front
Elastic hood drawcord with quick-adjust toggle. Cord ends are secured into the seam to reduce bounce while moving.
Reflective strip detail positioned under the zipper guard for added visibility in low-light conditions.
Deep zippered pockets concealed under the zipper cover, finished with reflective ‘Rising Forward’ detail.
Elastic cuffs for comfort, secure fit and protection from wind and light rain.
The AC400 Windbreaker Back
Reflective rear icon print for added visibility in low-light conditions.
Ultra-thin inner mesh panel with rear vents to maximise breathability and airflow.
Large rear horizontal pocket with side entry for storing the Puffer Vest and UL Running Cap, along with snacks and essentials.
The AC400 Vest Front
Reflective logo print on the left chest for added visibility in low-light conditions.
Deep zippered vest pockets. Left pocket includes a reversible pocket bag so the vest can pack down inside itself when not in use.
The AC400 Vest Back
Each baffle contains eco-friendly polyester fill — lightweight, compressible and highly effective for warmth without bulk.
Eco-friendly polyester-filled collar with full zip-up design for added warmth and comfort.
The AC400
Built for changing conditions
Not changing plans
Lightweight protection when the weather turns. Extra warmth when the temperature drops. The AC400 2-in-1 Windbreaker/Vest Combo was designed to adapt across seasons, training conditions, and everyday use.
Part of the UltraLite Running Series, the AC400 combines a lightweight windbreaker shell with a removable puffer vest, giving you the flexibility to wear them together or separately depending on the conditions.
The vest can be removed from inside the windbreaker and packed down into its own pocket bag, then stored neatly in the rear horizontal pocket of the windbreaker — along with small essentials like snacks, keys or other run-day items.
Made from lightweight premium polyester with eco-friendly polyester fill, the AC400 delivers practical warmth without the bulk. It’s a versatile all-conditions piece built for runners, athletes and anyone who wants one garment that can handle more than one season.
