4-way stretch nylon-spandex
Full range of motion. Holds its line through the squat and the commute.

Relaxed through the thigh, dramatically tapered at the ankle. Nylon-spandex 4-way stretch, zippered side pockets, 4 cm elastic waistband with drawcord, 2.5 cm ribbed ankle cuff. Quiet enough for the office floor, technical enough for the run.
Every choice tested against a cheaper one. The cheaper one lost.
Full range of motion. Holds its line through the squat and the commute.
Relaxed thigh, narrow at the cuff. Reads intentional under a leather sneaker.
Twin YKK side zips for the run. Phone in, nothing falls out.
Tight, recovery-knit cuff. No slouch, no shoe-eat.
Athletic. Between sizes — take the smaller.
