"Men's Brooks® Shield Hybrid Vest 3.0: When the temperature drops but you still need to get your miles in, the Shield Hybrid Vest 3.0 gives your core the protection it needs without the bulk of a full running jacket. This men's cold weather vest uses strategically placed THERMOLITE® 80gsm insulation to retain warmth where it counts, while zoned breathability keeps you from overheating mid-run. Windproof woven panels block the wind, and the DWR-treated fabric - made without PFAS - helps keep the elements at bay so you can stay focused on the run.The semi-fitted cut moves with you without feeling restrictive, and the soft collar lining and hand pocket lining add a noticeable level of comfort on colder mornings. Zip-secure hand pockets keep your essentials close, and the right pocket includes a built-in stash pocket for smaller items like a key or gel. Draft flap snaps hold the vest in place when you unzip for ventilation, and the longer zipper pulls are easy to manage with gloves on - a small detail that makes a real difference in cold weather. A reflective logo adds low-light visibility, and the shell is made from 100% recycled polyester with bluesign®-certified materials and UPF 50+ protection.Why Our Fit Experts Love It""I grabbed the Shield Hybrid Vest 3.0 for an early morning run when it was cold enough to need something but too warm for a full jacket. The insulation kept my core comfortable without making me feel overheated, and I really appreciated the longer zipper pulls - I had gloves on and didn't have to fumble at all. The stash pocket in the right hand pocket is a nice touch for keeping a key out of the way."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForThe Brooks Shield Hybrid Vest 3.0 is a strong choice for men who run through fall and winter and want core warmth without the weight or coverage of a full jacket.
