What Our Gearhead(R) Experts Are Saying:"I've worn the Core 1/4-Zip Top as my go to training layer on cool mornings and it dries fast enough that I never feel damp mid-run. The thumbholes keep my sleeves exactly where I want them when the temperature drops."Cool morning runs call for a layer that works with you from the first mile to the last, and the Core 1/4-Zip Top is built for exactly that. At Backcountry, we know a great midlayer has to earn its place by staying light and breathable under effort, and this top delivers with a fast drying, moisture wicking fabric that keeps you comfortable whether you're warming up or pushing hard. The quarter zip lets you vent or cover up on the fly as conditions shift. Thumbholes extend coverage over the hands for extra warmth at the start of a cold run, while reflective branding adds visibility for low light training. It's a clean, functional layer that disappears into your kit until you need it most.
