This is just about the only place you will find authentic Patagonia gear in the country. Patagonia is a California label, now synonymous with the fleece invasion of fashion and sportswear. It's the perfect shop in which to find gear for hiking, riding, climbing, fishing, and sailing, as well as for those fleece items you can't resist wearing around the house.
Bargains galore on truly sturdy, if slightly used merchandise can be found here: much of the stock is army surplus. There's no better place for a variety of outdoor clothing. Hiking in the Wicklow Mountains is one thing, but an excursion to Tibet is entirely different: if you want to be sure you are properly attired, then this is the place for both tips and the proper attire.
OK Sports is the place for all the sporting equipment you could possibly want, snooker gear, darts and tennis rackets, swimwear, clothing, exercise bikes, the list goes on. It's a place for the serious sports shopper and the staff, unsurprisingly, are friendly and more than willing to be of assistance.
