Under Armour Gear For the First-Time Trail Runner

Count on the "diamond-shaped fibers" of the UA Impasse technology of the UA OD Impasse Wind Jacket ($110) to keep water from reaching your base layer.

Not only do the UA Charged Bandit Trek Trail Running Shoes ($110) look the part, but the ventilation, high support, and flexibility all help you manage an uneven course.

Ideal for high-impact activities like running, boxing, and jumping, the Armour® High Zip Sports Bra ($60) features a full, frontal zip to keep things comfortable and supported.

Thanks to performance fabric and a structured design, the UA SPORTSMASK ½ Gaiter ($30) is comfortable and breathable.

Layers are critical for any outdoor sport during fall and winter. Opt for a vest like the ColdGear® Reactor Run Vest ($120) to guard against the elements and lock in heat.

The UA Meridian + Moisture Infuse Leggings ($100) are a great option for trail running thanks to their built-in stirrup style, which delivers coverage and a no-slip fit.

If you prefer more of a traditional sneaker type, the UA HOVR™ Velociti Trail Running Shoes ($120) is a great, durable option with a Vibram outsole and Mega Grip lug pattern for added traction.

A tee like the UA Armour Sport Hi-Lo Short Sleeve ($35), which relies on a stretchy fit sweat-wicking material, is a classic.
