Collection: Women's Midlayers and Fleeces

A trail running fleece or mid-layer are an excellent backup for cold weather running and to meet mandatory gear requirements at some of the biggest ultra-trail events.

Trail running fleeces and mid-layers help regulate body temperature when conditions change. They add lightweight warmth without trapping too much heat, making them ideal for cool mornings, windy ridgelines, alpine conditions and long runs where your pace can vary.

Unlike bulky jackets, technical fleeces and active insulation layers stay breathable and continue performing even when damp from sweat or light rain.

A good mid-layer also improves comfort and safety during trail adventures and ultras. It helps prevent chills on descents, keeps you warmer during rest stops, and packs down easily into a trail running vest when not needed.

The biggest benefit of using a layering system is it is highly adaptable for a wide variety of weather conditions.
