Print Story - Summit
design evolved from a conversation around "mountain logic" — how a runner forms the link between earth and sky through their ascent and descent of vertical terrain. Look for the ladder in the print, symbolizing that connection and transcendence.

Tumble dry low

Heads up — some color bleed may occur
Color bleed, especially with darker colored nylon/spandex blends, is common and could stain light colored garments if washed together.


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 love these tights. They are light, have compression and have pockets. So great, I ordered a second pair

Favorite Running Leggings

Lightweight with just the right compression. Pockets are perfect. Do not feel keys or phone when running. And love the burst of color. These are perfect running tights.

Best leggings I own! Hands down!!

These leggings don’t look too much different from other leggings in general, but let me tell you!!!
These leggings are LIFE!
I now own them in blue and green and plan to buy the black and multi colored ones as well because not only are they just the most comfortable leggings I own, but they are the most functional.
I run in them everyday with my phone in one pocket and my keys in the other.
The compression is just enough to make sure everything stays secure and they even keep my shin splints at bay.
The fabric is buttery soft and I just can’t imagine going for a run anymore without them.

Jennifer Manville
best leggings/tights ever

Don't sleep on these. I live in leggings and these 7/8 Groundwork tights are my favorite of all time. I use them for everything. Running errands, hiking, cycling, yoga. They are so soft and comfortable with great support and structure around the waist. The side pockets are positioned perfectly and not bulky, which is always my concern with pockets on leggings. I've bought several pairs of these, and even gift these to friends. They're that good.

Wanted to love these..

Taken these pants on multiple, single day 20+ mile loops with over 6K ft of climbing and each time I ask my self why I keep choosing these pants. They don’t stay up unless I’m consistently sweaty. Very annoying. It’s a wonderful color, though. Slightly thicker than lulu fast and free which are my go tos for running. 130 ish- 5’1. Training for 100m race. Love wearing these for errands and such. Not soo good with sweat marks.
