A DWR-coated nylon kurta, with snaps for goodness sake. Matching convertible trek pants coming later this month for the full "cult of climbing" vibe.
Proudly made in India from water-resistant trilobal nylon.
These run true to size but, like most things, look better when you size up.
Ravi is 6' with a 30" waist and wears an XL.
