"Men's Brooks® Shield Hybrid Jacket 3.0: When the temperature drops and the wind picks up, the Brooks Shield Hybrid Jacket 3.0 is the cold weather running jacket that keeps you moving. Built around strategically placed THERMOLITE® insulation (80gsm) and windproof woven panels, it blocks the bite of winter air while zoned breathability helps prevent you from overheating mid-run. The semi-fitted cut moves with you without adding bulk, and the DWR-treated fabric - made without PFAS - is designed to shed the elements so you can stay focused on the miles ahead.The details on this jacket are well thought out for runners who actually train through winter. Draft flap snaps keep the jacket in place when you unzip for ventilation, so you get airflow without the jacket flapping around. Cuff gaiters seal out cold air at the wrists, thumbholes add an extra layer of coverage, and the longer zipper pulls are easy to manage with gloves on. Zip-secure hand pockets with a right-side stash pocket handle your essentials, and the soft lining on the collar and pockets makes a noticeable difference on cold mornings. The shell is made from 100% recycled polyester, the lining is 100% recycled polyester, and all materials are bluesign®-certified. A reflective logo adds low-light visibility, and UPF 50+ protection is built in.Why Our Fit Experts Love It""I took this out on a cold, windy morning and was impressed by how well the windproof panels did their job without making the jacket feel stiff or heavy. The draft flap snaps are a small detail that makes a real difference - I could crack the zipper for ventilation and the jacket stayed right where it should. The cuff gaiters kept cold air from sneaking in, which I really appreciated on longer efforts."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForThe Brooks Shield Hybrid Jacket 3.0 is a strong choice for men who run through fall and winter and need a jacket that handles wind and cold without sacrificing breathability.
