Description

Tailored from Lolë's Eco Power Tech fabric — 80% recycled polyester with elastane — for a 4-way stretch and breathable performance you'll feel from the first warm-up.

A center-front zip closure with stand collar locks in heat on cool mornings, on-seam invisible zip pockets stash your essentials without breaking the line, and built-in thumbholes anchor the sleeves through every stretch. A subtly curved hem flatters and moves.

Backed by GRS, Blue Sign and OEKO-TEX certifications — running-ready without the planetary cost.

About the brand

Lolë was created in 2002 by Evelyn Trempe when she spotted a gap in women’s technical outerwear. She noticed that the selection of women’s travel and outerwear was bland and lacked style. So she set off on a mission to create an inspiring collection for women who want to get out there and live out loud every day.

Today, Lolë inspires and enables individuals to embrace the outdoors in style. Through thoughtful, fashion forward outerwear based collections, that move with you.

  • Do not bleach
