Pre-shaped sleeves, elastic bindings, and a bonded single-grip adjustable hem ensure a secure, flexible fit. Functional details include YKK® zippers, a chin guard, two zippered hand pockets, and a watch window for easy access to data mid-session. Finished with a printed logo, PFC-free DWR treatment, and over 50% bluesign®-approved fabrics, Jacket Energy delivers reliable protection and comfort for demanding winter training.
