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 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.

Great tights

These tights do the job. I like them on easy runs when it's colder than usual. I find it hard to get and stay warm when doing easy runs in cold weather. So these are perfect for me.
