Women's Pentane Tights


These tights hug in all the right places for an all-around stretchy, breathable, and wicking piece that delivers total freedom of movement during mountain training.
FIT: Trim fit
COLOR pewter
SIZE: M - In stock

Sure, we could have made just a plain pair of black running tights. But why be normal? Not only are these lightweight, super stretchy and uber wicking—they’re also high-vis. The ever-so-subtle pattern in the fabric is reflective. So without rocking neon, you still make yourself visible on those dark winter training runs. A stylish scalloped hem and sleek waistband make for one good-looking tight that can keep up with you, even with your afterburners on.

Great... for slim thighs


Love the reflective panels - discreet, but great at night. Fit is a little off - length hits a bit further above the ankle than I would like, and the top hits higher on the waist. The drawstring helps, but these still tend to fall down unless you really cinch them around your natural waist -I prefer tights that hit at the hip. I'm 5'7", 160 - all in the legs, a size large was the right size if only it fit a little different. These would probably fit someone less 'curvy' or 'athletic' better. Still, they are super soft on the inside and I'll be keeping them for evening runs around the city.

Of course this tight sold out!


I only wish I bought more than 1! I have the grey on order but hope to get another black as soon as they are available again! These tights are soft, mid-weigh, breathable and flattering. Great for cold weather, from a 20 mile hike to a 3 mile run, or a relaxing yoga class they are just perfect. They sag just a bit until you break a sweat then they are the perfect, non restricting leg wear. LOVE!!!

Hello, I'm trying to see if these leggings will fit my girlfriend. I looked at the size chart but still cant figure out what pant size corresponds to "medium" or any of the other sizes of this product for that matter. Any help?


Hi Fletch, I have some measurements that may help. The Medium have a 29" waist, it decreases 1" for each additional size down and increases 1.5" for each additional size up. The low hip measurement for a Medium is 32.25", it also decreases 1" for each additional size down and increases 1.5" for each additional size up. The inseam of the pants for a Medium is 25.5". it decreases or increases 0.5" for each additional size down or up. Thanks for contacting OR,


Hey all - wondering if these pants would be a good choice to wear hiking and or to yoga? If one was to downward dog or to be working with kids - do undies show ? Psyched to try!


Hi Prunes, Sorry for the late response. I reached out to our Product Development Team, and this is what they said. "They (OR Women's Pentane Tights) are a running tight. They should be dense enough to have no show through. They are super stretchy and they should be worn true to size." I wear the Men's version on early morning hikes and they are great. Haven't tried them in yoga, but I'd imagine they'd perform well. Thanks for contacting OR, Paul
