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.

Decent tights, but not for longer runs

The tights seem to be well made, the fabric feels good against the skin and they are a good thickness for winter wear down to freezing temperatures. I also really like the large pockets on them and how easy these are to access while running. They fit ok, but like another reviewer I find they are baggier than expected in the crotch. The biggest downside for me is that I find some of the seams cause chafing in intimate areas if worn for runs longer than 4-5 miles.

Best running bottoms I've used

Second pair of these , really good fit and pockets r great for holding lots of stuff, wash out,hold shape and unbelievable comfortable for long runs

Nice tights

I really like the fit and material on these tights it is quite tough and supportive, even when it gets wet. The pockets work better than many, although I would like the rear pocket to be larger so that my phone could go there, when I put it in the side pockets the small amount of bounce gradually pulls the tights down so requiring regular adjustment. They are fine for lighter items such as gels or gloves though

Comfortable and practical tights

Light, true to size tights. Very convenient having two pockets for phone, keys etc. Even better that the pockets are designed for items not to bounce around. Last but not least, incredibly comfy.

Well designed winter wear

Well designed winter wear, well positioned pockets that don't interfere with your stride (played football in them, and my phone was snug and secure)
