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.

Winter go-to running leggings!

These are my go-to winter leggings when it's 30F. I'm not sure how "brushed" the interior is, given that my legs don't burn up when it's above 50F outside. Aside from that, they are very comfy with plenty of pockets, and I like the hems at the ankles. I also like the length and ability to tighten the waist band. I'm slightly disappointed when I've already worn them during the week and don't have them clean for my weekend long runs!

I am 5'9" and purchased the Small. I normally purchase athletic leggings in Medium but went with small due to the sizing chart. Fits perfectly.

The best

So soft and comfy! Versatile tights-warm enough for 35 - 50 degree weather- am a marathoner in NYC- we get a huge range of weather and these are great for many temps so far. Super practical- tons of pockets. They do run a little big ( am 5 8 usually a med) if you cinch the waist however still comfy even if you have a phone and keys in the pockets.

Comfortable tights

These tights are comfortable and will fit my needs but definitely not as warm as another pair of winter tights that I have. For temps in the 32+ range they are excellent.

Great tights

I have been a loyal lululemon tight wearer but these are actually better for me on longer runs (> 10 miles). For some reason, they keep me from chafing in weird spots unlike the lulu’s. Highly recommend.

Durable

These tights are crazy comfortable and perfect in 25-35 degree temps. They are super lightweight even though they are for cooler temps and layer perfectly with the transit pant. The highlight of these pants though are that I took a sidewalk fall on a run recently and they did not rip or tear at all. Super surprised…I’m officially a Janji fan for life.
