Meet the GwenUV Skort: designed with UPF 50 for sunny days, a built-in liner that stays put, four cargo pockets, and moisture-wicking fabric for whatever mountain adventure you get up to.

Same sun. Different personalities.

GwenUV, styled for all-day plans (and no plans).

What is UPF? Here’s the breakdown. ☀️

UPF (Ultraviolet Protection Factor) measures how much of the sun’s UV rays a fabric blocks. UPF 50, like in our GwenUV jacket, pant, and skort, blocks about 98% of harmful rays — keeping you protected without extra layers or sunscreen.

Our GwenUV fabric combines this protection with breathable mesh, moisture-wicking fabric, and lightweight design, so you stay covered, cool, and comfortable whether you’re on the trail or in the city.

The Bastille Trail Pant, named in honor of Anne LaBastille — a writer, ecologist, and backcountry pioneer who built a life of radical self-reliance in the Adirondack wilderness.

Anne LaBastille didn’t just go into the wild. She made a life there. Cabin-built, self-taught, and unapologetically solo, she turned the Adirondacks into both her home and her proving ground. Through her four-volume autobiographical series, “Woodswoman” and beyond, she showed generations of women that the outdoors isn’t something to visit — it’s something you can belong to.

Our Bastille Trail Pant carries that same spirit: self-reliant, no-frills, and ready for wherever you decide to explore.
