sustainability

Groundwork Knit is made using a premium grade nylon that has a significantly tighter woven filament than standard synthetics. Tighter filaments mean less microfiber shedding in the wash-cycle, plus greater durability of the garment (longer lifespan, more wearing).

Groundwork Knit fabric is also bluesign® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.

Groundwork tight

I love these tights. I think I’ve worn them just about every workout since they arrived. They have seen me through outdoor runs; hikes; spring x-c skiing, yoga, and strength sessions. They feel great and look awesome. I’ve used them in temps 28-50 F and felt comfortable. Thank you for my new tights. I love them ❤️

Race-day tested! Warmth meets durability

I recently wore these during a half marathon in Rhode Island where it was 20F at the start, felt like 5F, with about 15-20MPH winds. For full disclosure, I work for Janji, and moved to New England this past year from the South, so I'm a bit of a baby about the cold. Two observations: 1. Once I started running, these were definitely warm enough, even with the gusts of wind. I'm on the taller side, and could have done with even more length while we were standing around, but I didn't mind once I started running; 2. This fabric is DURABLE. I never fall while running, but I tripped during the race and hit the road so hard my bib ripped off, but the tights themselves stayed intact! Definitely a silver lining in an otherwise embarrassing moment!

Groundwork Winter Tight

I love these so much. They are true to size. They are soft and smooth but also a comfortably snug stretch-fit. In a nutshell, they do what they are supposed to do while remaining 100% comfortable. I do have warmer tights (I live in Wisconsin, it's below zero often.

Great performance tights!

These are a great pair of winter running/ racing tights! I won't pick them for days below 20 because they aren't my thickest winter tights, but I think that's what makes them great for racing/ days you want to go fast (and they could work as a base layer tight if your want to layer)! For reference, I do own the 7/8 groundwork tights in size Small and would say that these full length ones aren't quite as snug in the waist (which I don't mind at all!)

These pants are warm and comfortable, plus they stay in place while running AND the pockets are great. I’ve been looking for winter running pants for years, and these are it! Love the jasper color.

Super comfy but a bit short

Great leggings, pockets are incredible, but not having a tall option is really a bummer -- especially because they are supposed to be winter tights. I'm 5'11" and they a couple inches above my ankle, right where my Darn Tough socks hit, so its annoying to have to keep pulling down my leggings or pulling up my socks to not leave any skin exposed. I'm keeping them, but disappointed at the lack of options. They essentially fit me like a 7/8 legging. Please Janji!! Make a tall option!!

Nice leggings!

I have run in these a few times so far and really like them. They’re not too hot, but they have kept me warm in low 30s (coolest I’ve tried them in this far). I am going to ding them a star because I do have some issues with them staying up around the waist/butt. I have this issue with other brands and was hoping these would be better. They are better, but the issue still exists. Maybe it’s my butt?

Great- wish they were warmer!

I love these tights! Super comfy and fits well. I guess I thought winter tights were warmer than what these are, and I still have to wear another layer with them on my runs that are below 25 degrees. But that could just be me! Otherwise, love them!

Perfect for winter in Maine

Excellent running tights for cold weather in Maine. I also have the regular groundwork tight and the increased thickness of these is perfect. One thing that bothers me about this pair is the design of the inner pockets on the front is a bit irritating on my skin - the no slip rubs on my skin while running in a way the original groundwork tight doesn’t. I just need to tuck my shirt in and it’s fine but seems like a bit of an oversight, that’s the only reason for giving these a 4 instead of 5
