"Men's Brooks® Momentum Thermal Pant: Cold-weather running calls for pants that keep up, and the Men's Brooks Momentum Thermal Pant is built to do exactly that. These men's running pants use GO2 Warm™ thermal fabric to trap heat without adding bulk, so you stay comfortable from the first cold mile to the last. The semi-fitted, tapered leg gives you a clean silhouette that moves with you rather than against you, making these a reliable choice for winter training runs when the temperature drops and you still need to get out the door.The GO2 Warm™ shell is made from 79% recycled polyester and 21% spandex, with a 100% recycled polyester lining and brushed fabric at the waistband for added comfort against the skin. Ankle zippers and an internal drawcord let you dial in the fit, whether you're layering over a base layer or heading out on your own. Two zippered pockets keep your essentials secure while you run, and reflective branding adds low-light visibility when early mornings or late evenings are your only option. The 30"" inseam rounds out a fit that works well for most runners without extra length getting in the way.Why Our Fit Experts Love It""I took these out on a cold morning run when it was hovering around freezing, and I was surprised at how warm they felt without being heavy or restrictive. The ankle zippers made it easy to get them on over my shoes, and the pockets actually held my phone securely the whole time. If you run through winter and hate feeling like you're wearing a sleeping bag, these are worth a look."" - Sullivan, Road Runner Sports Fit Expert, Naperville ILWho It's Best ForThe Momentum Thermal Pant is a strong choice for men who run through fall and winter and want cold-weather running pants that balance warmth, stretch, and a clean fit.
