When looking to keep runners cozy during workouts, activewear brands have traditionally utilized a combination of layering and insulation. And while this configuration keeps its wearer toasty during warmup and cool-down periods, it can often result in overheating amidst rigorous exercise. Recognizing this issue, lululemon has managed to deliver an equally-warm garment that hugely minimizes weight and bulk through the use of an advanced thermoregulating material and knitted construction with its new Engineered Warmth Jacket.
Engineered specifically for outdoor training, this full-zip jacket allows for an unrestricted range of movement and is composed of a textured four-way stretch nylon, poly, elastane, and Merino wool blend that’s constructed using a special 3D weave which allows the material to be naturally thermoregulating. Soft to the touch, the jacket also boasts a thicker weave in key areas around the body’s core and the outside of the arms that helps to bolster the material’s thermal retention. Outfitted with custom lululemon-branded composite zipper pulls throughout, the jacket also sports a zip-through collar and secure zippered pockets with a hidden phone sleeve that’s internally anchored to the main construction to prevent bouncing around during physical activity. Offered in multi-knit gray, black, or dark olive, the lululemon Engineered Warmth Jacket is available now for $168.
