Super comfortable

Great running pants, i use them for all types of running during cooler weather. They fit great and don't sag at all during runs. The only thing is the pockets are on the small side, although i can fit my giant phone in them, it's not comfortable. Pockets work great for keys and other small things though.

Do everything pants

These will be my go-to pants for everything. Nice fit, perfect warmth for 45-65 degrees, and the pockets are perfect for carrying all the necessities.

Perfect pants

I am an athletically built fun-sized human with a decent rear end, so finding pants that fit in the size I feel like I should wear is impossible. But not with these pants! I wear them in day to day life as well as running, and they don't move, chafe, or do anything I can talk bad about! If you are hesitating about these, don't. Buy them. You won't regret it!

Never want to take them off

These pants are so comfortable, functional, and flattering. Love the zip pockets and nice mid rise. The material is INCREDIBLE—so soft and comfy. My absolute favorite bottom to wear. Wouldn’t wear for climbing, I don’t think the fabric would do well with abrasive surfaces, but for running/yoga/travel/lounging, amazing!!! I’m a long legged 5’8”, and these hit maybe an inch above the ankle.

Love these-true to size

Love these pants, they're super cute, love the tight cuff and the length, they're really soft and comfortable, they look great. I'm on the edge of xs and small in the size guide so the reviews convinced me to size up, and that was totally wrong, they arrived and were like parachute pants on me, I exchanged for the xs and they're perfect. I also have the Transit Tech pants in xs, these do fit slimmer in the thigh but otherwise the sizing is consistent.

Perfect winter running pants

I was a little hesitant since I had a sizing issue with Janji pants in the past, but this one is true to size and such great asset to my winter running wardrobe. They are light and soft, but surprisingly warm, and made my early morning runs in freezing temperatures so much easier and fun. The back pocket is also well made and holds my phone without any movement. The only thing I would improve is making a slight longer version that would cover the ankles. Other than that - highly recommended!

Love

I have purchased two pairs of these pants for cold weather running and they are perfect. Roomy enough to wear a base layer underneath and perfect on their own.
