Fall/Winter Running Staple

Love these pants for when the temps drop below 45-50°! Super soft fabric, zipper hand pockets, and large zipper pocket in the back. Bought all 3 colors and a few presents for friends for the holidays! Don’t 2nd guess this purchase…get ‘em while you can!!!

Great Pants! Select Size Based on Fit Preference

First of all, I bought the men's version because I wanted the longer inseam. I own 2 pairs. The 1st pair I bought was a size medium and the 2nd pair a size large. I have a 32" waist. The medium felt more like a semi-fit almost like a loose tight than pants feel. Running in them is good because they do have a good stretch and move with you. The size large has more room and definitely feels like pants and running in them feels good too. Overall, I would recommend look at the size chart and select your usual size if you want the semi-fit (which is what they advertise) or select one size up if you want a looser fit. I personally prefer a looser fit for running pants. Other than that I love the pockets and the lightweight material.

Would buy again

I really like how these joggers feel and fit. They are great for pre/post runs in the Summer heat, as well as warm for those cooler up North days and nights by the water or campfire.

My favorite joggers

Long short, these are my favorite joggers. They fit and feel great, and are functional. I would wear them all day everyday if possible.

My only gripe is we need them in more colors!

Smooth like butter!!

My husband is so obsessed with these running pants, he now owns them in every color.
The fabric is amazing and the only issue I have is that he wears them everywhere and refuses to TAKE THEM OFF!

I loved this pants

This pants are extremely comfy, the only thing I would change is make them a bit longer. They are still so nice to wear, so I still give them 5/5.

Quality Product

Love its color, material quality, and the thoughts that went into its design. Fabric is incredibly soft, stretchy but also has great form retention. The waist and ankle bands hug the body without compressing against it. I would rank Jangi’s overall product quality to be on par with Rhone and one step above Lululemon. The pants, being designed for runners, does run one size smaller than aforementioned brands. I typically wear S but had to exchange this one for a M.

Good Enough for 197 miles across NJ.

I wore these awesome joggers for my run across the state of New Jersey. When I made the switch to wear them around half-way (90+ miles in), that was the change I needed. Soft like velvet and an excellent freedom of movement, and warm and insulating in the heart of winter, these pants really impressed me. I never once worried about chaffing. I never once worried about anything with my pants rather. That is how running should be.

Thank you Janji!
