Obessed with these!!!

These are my favorite pants...and I've seem to have lost them so I'm hoping they come out with more! I wear them running, hiking, lounging, anywhere. They're thin so I don't get too hot in them, but they repel water, so running or moving in rain or a bit of snow is pretty comfortable. Amazing pants!!!

Best pants ever

These are my favorite pants. I wear them for running, but I also wear them for everything else too. I just wish they came in more colors!

All day, every day

I could not recommend these pants enough. I have never been a winter runner but this year I set a goal to put in 100 miles a month throughout the winter. I got these pants at the end of November and wore them for every single run I did in December, January and February (and colder days in March). They are so soft and comfortable, high quality, and great for everything from running to running errands to lounging on the couch.

THE BEST PANTS EVER

I don't normally write reviews, but I just have to. These are the best, most comfortable pants ever!!! I literally wear them every day. They are so soft, the perfect amount of stretch, and easy to get on/off. They are perfect for any activity. I've worn them running, to the office, to the bar, you name it.

LOVE. Please make them in black!

Love these so much. I'm 5'7" and 145 and a medium fits great. They are soft, very nice looking, and so comfy. I wear these almost every day to work from home. I haven't ended up running in them much since a pant allows me to chaffe in a way that leggings prevents, but that is a me thing. I also wearing them under my snowpants for skiing. If they made these in black, I would buy them in a heartbeat.

Warm and Wicking

I really love these. I live in FL, so I don’t have to run in truly cold temps. But these have been perfect for our winter here (40s-50s). They are very comfortable, breathe well, and fit nicely. I wish they were a little bit longer and/or the ankle band was a tiny bit bigger but I have pretty long legs (so that might just be a personal problem). I’m 5’9” and 160 lbs. and bought the mediums. They fit me about like a glove or tights, but are not tight, if that makes sense. I could have sized up to a large for a looser, baggier fit, but I have no regrets. Overall, two thumbs up! I got two pair of these - one in each color offered - and am sure to be enjoying them for a long time to come. They are just a joy to run in.

Really comfortable!

I received these pants yesterday and took them for a 4 mile run this morning in 44 degree fog. I was pleasantly surprised to find they kept me warm! The cuffs at the bottom are tight, which helps keep cold air out. The fabric is that insanely soft buttery fabric Janji is famous for, and it's incredible. The pants stayed put, no sliding down or riding up. I put my iPhone 12 Pro w/case in the front side pocket and it was fine there, but I think it would've also fit (tightly) in the back waistband pocket. I got a small, which is what I wear in all Janji pants. I'm 5'7", 135ish, and the small fit ok but was a little smaller on me than I expected, and I've seen other reviews since that mention they run small, so I would say I agree with that. The one complaint I have, and it's super minor, is that the color is not what I expected. I got "Nightshadow", which looks like a vibrant dark teal on the website, but in actuality, it's a muted grey-blue. More grey than blue. And definitely not the teal I was expecting. It's not a big deal because I still like the color and the pants are great no matter what color they are. But I would've preferred the more vibrant teal. The pants didn't show much sweat, which was a plus! I would like to see these in other colors!
