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.

Perfect tights for cold weather runs!

Wore these for the first time for a 4 mile run on a crisp 42 degree December morning. The tights were the perfect fit and I did not get too warm. I’m excited to try these on even colder days. The reflective stitching is a great feature for the early morning runs before the sun is up!

Fits great and good storage

I’ve really come to appreciate good pockets on a run, and the pockets in these tights are the best configuration I’ve run across.

Very comfortable

I’m short (5’6”) so I’d really prefer a men’s version of the 7/8 Groundwork Tight so the inseam wouldn’t be so long, but I can’t convince myself to return these - they’re so comfortable!

Great fit. I wish they were an inch longer. Good compression.

Great gear addition for colder weather

I've always wore shorts when running. Brought my first pair of "pants" that covers legs. Very comfortable and great fit.

Groundwork Tight Review

Good fit- ordered a medium and large as the return option is a good one to have. Kept the large but might have been able to use the medium, Has good, functional unobtrusive pockets. I wouldn't mind if it was a bit of a thinner material as I am not sure I would like to try to run a fast time in them. They should work well down to 0 to 10 degrees for me anyway, if I would choose to run when it is that cold. I wouldn't wear them hiking/camping unless it was winter. For what they are, I give them 5 stars.
