The only Sweat-pant you need

I snagged a deal on these and loved the color.

I had some old, fleece sweats I kept around for really cold days and these have replaced them.

They’re incredibly efficient at wicking moisture and retaining heat in cold temperatures.

I run with these with no issue and I also use them for strength training, lounging, traveling (great for airplane)…anything and everything.

The color (Moonrise) is fun without being flashy.

I bought some joggers from a brand that starts with a “V” and ends with “uori” around the same time and immediately could tell the difference in quality between the joggers; the Janji product is significantly better quality.

I’m going to buy a couple of pairs (hopefully in more colors) and continue purchasing this product.

Fit: I’m 5’8 normally a 34W and went with a Large to give my dumpy..err, posterior, some room along with my quads.
And I have really skinny/defined ankles so the taper drapes beautifully to my dimensions.

I can’t say enough positive things about this product, it’s really put a joy in my wardrobe and I hate putting them in the hamper for a wash.

Cozy AF

I predominantly use these for lounging and the gym. The fit is exactly spot on, slim and tapered. When you take that into account the fit is exactly as advertised. They are warm, durable, AND COZY AF. They've also acted as a perfect layer under a shell during cold winter hikes. I highly recommend these

Best running pants I’ve ever owned

Without a doubt the best pair of running pants I’ve ever owned. The cut is trim, but not too tight, and the fabric is super comfortable and moves well with you. I like that there is no zipper at the ankle either. I’ve found myself wearing these outside of running/hiking because they are so comfortable

As good as the reviews say

I don't often feel compelled to write reviews but I did for these pants, so here we are. I bought these to run during a cold snap this winter and they have performed admirably. First run in them was two hours in negative (Fahrenheit) temps and they were incredibly comfortable, breathable, and shed the falling snow really well. Turns out they are just as comfy and nice for hanging around home too.

Love these pants. Can't comment on long term durability yet, but assuming they hold up I can say they are well worth the money.

Great winter running pants

These pants keep me nice and warm while running, even when the temps get down in the teens. They are also super comfortable and I love all the pockets!

Amazing Fit & Feel, high quality pants.

High quality workmanship, extremely comfortable, great for cold runs. Pockets are perfect. Fit is perfect. Great looking!

My main use is running when it’s 40 degrees or less outside. Also intend to use them for winter hiking and as a layer when camping.

As a bonus I’ve had two customer service exchanges relating to these joggers and a pair of Janji shorts and both times I was contacted back very promptly with an over-and-above resolution to the issue. They stand by their products — the customer service alone makes these pants and all Janji products an amazing value. Highly recommend the brand to all.

Great running pants

I don't usually where pants while running, but on the really cold days the Mercury pants are my jam.
