great pants

These are great--Janji has really dialed in the fit and material. This year's are a couple inches longer than the ones I got last March, which is great. They still show your ankle but last years were almost capris on me (I wear L and have a 35 inch inseam). This year's model is also a bit softer to the touch, but has the same great just-right stretch and fit. They breathe and wick moisture perfectly.

The waist pocket in the back is great for keys or a small phone (e.g. iphone 6) but doses not accommodate today's larger phones (which are pretty heavy, so maybe you don't want that anyway).

Mercurys vs. Izzy

I’ve run in these pants a couple of times in cold weather (mid 20s), including running in them for the first 16 miles of a 50K trail ultra a couple of weeks ago. They worked well. Then I ran 6 miles in them this past Sunday in snow, ice, wind, and 25F temperatures. They were surprisingly warm. I also noticed that after wearing them for about an hour inside the house when I returned they were dry. I couldn’t believe how fast they dried after running in all that snow. These pants are great!

Another Janji masterpiece.

Another multifunctional and awesome product from Janji. Useful pockets. Great feeling fabric. Wear them around the house or outside for a little extra warm. Perfect for a hike or run. Stylish enough to wear casually. 5’10”, 140 lbs.

Great for running and leisure

Biggest criticism of these pants is whether to use them for running or to wear around the house. Like the first pair so much I bought a second and they are great to run in when the temps are around 50 or lower. Everything I have bought from Janji has been top-notch (pants, shorts, hats and sweatshirts).

Mercury Track Pant

I simply love them!! I typically run in tights but wanted to try something more versatile that had lots of pockets and could go from trail to road to coffee shop. I honestly wouldn’t change a thing about them. The back pocket along the waist is amazing. No bounce from my IPhone 11 and fits perfectly with room to spare. Please make some shorts with the exact same rear pocket configuration!!

i like these pants

These are very good pants. I've never been one for track pants, but the positive reviews won me over. The fit is superb--somehow snug but loose at the same time. I'm currently working from home, and I lounge around all day in these pants. In these uncertain times, these stylish, athletic pants are no small comfort. I have two pairs.

Very nice running pants. Have only use them a half dozen time so far but very pleased as to how well they are made and designed.
