The Compression Base Shorts are the layer that starts the day before everything else does. High-waist construction supports the lower back and core. Graduated compression encourages circulation through the long sits and the long days. 83% nylon, 17% spandex. Built to sit flush against the skin and disappear under tailoring, denim, or workwear. No rolling. No adjusting. No reminder that they're there.

“Flew 14 hours to New York. Zero swelling in my feet. Best travel purchase this year.”
“Keeps the cold out and my back straight. Good stuff and hugs my little big friend tight.”
“Velikost M sem moral zamenjati za L, ker mi je bila okoli prsi preveč tesna. Vračilo je bilo sicer preprosto. Velikost L mi odlično pristoji in pod delovnimi srajcami opravlja točno tisto, kar potrebujem. 👍”
