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.

Pretty close to perfect

First, the color choices are excellent. Tired of all my running tights being black. Second, the material is great, no seams where they aren’t needed and the material is super soft, not too thick and not too thin. Third the pockets are great. I don’t carry my phone in the thigh pocket but my car key and a few gels stay nicely packed in the back lumbar pocket. The only downside is they do feel like they slide down a little bit while running or wearing them which could be related to my body shape or the shape of the tights. Regardless these have become my favorite running tights.

HUGE improvement over previous edition

I love these. They are the perfect running tight for winter.

The previous edition was warm but the waist was horrible. This edition has solved that issue! Can run with a phone in the side without worrying about it tugging your pants down etc. have tons of hidden pockets.

Have run in the very cold with these with no issues. So good I bought a second pair.

Amazing

The new fit with the pocket redesign is incredible. There are actually two usable pockets on the side. One high up that's shallow and one that's just below it that's deep which is really good at holding a 250ml softflask. I really hope they update their half tights with the new fit and pockets.

The best running tights out there!

These tights are amazing. They are snug but flexible, fit perfect around the ankle and don't fall off the waist like a lot of tights do (on my body at least). I've run in them in 20 degree weather and didn't feel the least bit cold! Really happy with this purchase.

I bought 2

I typically buy Under Armour, but I like these better. They're very comfortable. I originally bought a black at my running store and opted to get a huckleberry one as well online. They're pricey and the drawstring is short, but I like them a lot.

Best tights out there?

I've tried a number of tights and the Groundwork Tights have to be the best I've found including alo, Under Armor, Gymshark, etc. I originally bought the Mountain color during Black Friday and instantly liked them so I then also bought a Huckleberry pair. These are great for running, walking and even yoga. My wife is even a little envious because of all the pockets.

The only caveat is that the Huckleberry pair I have already have a small hole along the seam on my right inner thigh after only wearing them twice. A little disappointing but even my wife has seen similar problems in other legging brands she has.
