These silver No Kai' Oi sparkly stripe sweatpants have been crafted from metallic fibres. Fitted with an elasticated waist and cuffs, this pair are high-waisted and feature side seam pockets. Apparently optimists live longer, so if you can see the silver lining of wearing this No Kai' Oi pair then you may be able to skip the workout and wear them to cheer up the pessimists who refuse to greet you.
