Really nicely laid out large shop with a good range of hats from the website. Staff are super friendly and helpful without being overly intrusive. Found what I wanted and the staff prepared it ready for me to wear for no additional cost
UA is a multi-brands fashion emporium in Roppongi Hills, just next door to Estnation, yet another multi-brands store albeit larger (& more pricy). UA's assortment is generally less edgy than its neighbor, hence more wearable & pocket-friendly.
