Love the pants

I got these on sales. Had been thinking about them for them a while and finally bought a pair. So glad I did. I love them and have worn them almost constantly since I got them. Really comfortable and fit true to size.

Love these pants!!!

I purchased them in the small and medium. I was going to send one back, but they are both so comfortable. The medium is looser in me and nice for after my run. They are so warm and cozy. The small are shorter on me, but fit a bit tighter and more confirms me for running. I’m keeping them both.

Love these pants

I’m super short and small so I have to wear women’s sizes. These look great, my wife is even more attracted to me when I’m in them

K
Kim Kobata

Great fabric, 4 stars because they are a bit longer than I’d like and because of the cuff at the bottom they are difficult to hem. I’m 5’2”

Great pant for winter running

These are amazing and comfortable for cold weather runs (30 degrees or lower). Extremely comfortable, breathable, and amazing pockets (pants that fit assigned female runners often have crappy pockets or no pockets and I tend to drop things but not these pants). Highly recommend so long as they hold up since they aren't cheap!
