New Triwire

My second fave pant behind the kl1’s. Still rocking my first gens as I only wear then casually or to jog in. Fabric seems it may be stronger than last ones too but they’re new so we’ll see. Reshaped better from the first gens too.

They fit so well!

I have another pair similar but they don’t fit nearly as well. Really love how these hug my legs. Not uncomfortably tight in the waist, and I use the drawstring to keep the tight. Super comfortable!

The KL1s are the perfect workout pants. Have multiple pairs of the KL1S and KL2S and the KL1s are still may favorite for training sessions. They're fitted more than the KL2s and lighter in the best way possible!
