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.

I just raced in these, big phone and keys in the pockets, and never knew they were there. Can’t wait to get more. Will be my go to tights from now on!

Phenomenal Tights

Easily my favorite running tights. Perfect fit for me, and the pockets add so much utility. I use the deep side pockets for stashing my gloves, the smaller side pockets for snacks, and the rear pocket for my phone. As an added bonus, I love that the 15% off Janji Collective discount stacks with sale prices. $60 is a fantastic price for tights that'll keep me running in the cold winter weather.

Warm, Comfy, and Good Looking!

I moved from CA to MN this year and everyone keeps telling me it gets COLD here. So I've been looking for something to help keep me running when the temps drop. I've run in a bunch of other tights, but they weren't quite... ummm, supportive enough... to be worn without shorts. These things are PERFECT. I tried them for the first time on my long run this weekend and they were actually a bit too warm for the mid-30s. I wore them again today sub-freezing and felt just fine. I'll be picking up another pair soon!

I'd love to see these in some of your artist designs.

Fantastic

Wore this tight today at around 42 degrees. It was perfect! Easily fit my phone on the side, so ran around for some tunes. And best of all I can wear this when it's dark out thanks to the reflectivity!

Don't read another review, just buy these!

I have been using UA Cold gear for cold weather running for years now but I have recently switched from my “old man” MP3 player to using Spotify to run so I needed tights with a phone pocket. These come with side phone pockets on both sides, so the designer even considered the needs of lefthanded people! The side pockets are in the perfect place to secure you phone and make sure it doesn’t fall out (or bounce around) while still providing easy access through the pocket for volume control. It’s also easy to remove and use without having to stop if you needed to access the screen like I did on my run this morning. My UA didn’t have any reflective parts on it and even thought I wear the NB Hi-Viz Beacon jacket more reflective bits doesn’t hurt since I primarily run at night (early morning). The fit is amazing and so much better than the UA which kept me warm but I always felt I needed a little more support in the groin area and seemed to need pulling up several times during just a short 5k run. The waistband is also super comfortable and stays in place even with the weight of my phone in the pocket. I wasn’t crazy about spending $94 when all I really needed was a better way to carry my phone but I’m now glad that I did. My UA tights will now be restricted to base layer for skiing and these will be my go-to running tights! Comfort, functionality and quality what and awesome product! I have a new favorite brand for running gear!

Immediately felt great, comfy in a range of temps!

Bought these a couple weeks ago and already have been able to wear them in temps ranging from around 25-50- and they've felt great in all of them! Warm but breathable, fit perfect right away, no chafing so far yet either! 5'10, 32'' waist, size M has been perfect!

I love these!

These are the first men’s running tights I’ve actually liked for the price.

I’m 6’5” with a 34 inseam and these tights fit great. The laser cut, seamless ankle would also help people with shorter legs stay comfortable, I bet.

The material is soft yet compressive. There are a LOT of pockets. The front area is good for modesty but also isn’t unflattering and doesn’t bunch or sag like other brands I’ve tried. I always wear Nike Pro 6” training shorts/underwear to keep my bits under control when running and found they work great as underwear for these tights, too.

Fabulous

5’10”, 160#, male. Fits right. Not to loose, not to tight. It would be nice to see these tights in some sort of pattern, helps obscure any parts you want obscured.
