Patagonia Camp 4 Tights

Patagonia.com says:
Luxuriously smooth tights, with a clean design that complements dynamic climbing. Camp 4's are made from breathable and lightweight organic cotton, with spandex jersey for stretch. The thin, low-profile waistline features two ties that equalize pressure and customize the fit under a harness. With a generous flare at the hem to accommodate stretch moves.
