I was already a big fan of Globetrotter from their huge outdoor goods shop in Barmbek. This shop downtown is not nearly as big or showy, but it does have two floors of merchandise, and the design and layout is nice and approachable. Just don't go looking for the carousel of kayaks (like they have in Barmbek).
They primarily have men's and women's activewear and outerwear on the first floor, along with backpacks and a few other small things. Great options if you need a fleece jacket, a raincoat, or a pair of rain pants (this is Hamburg, after all).
The second floor has shoes (mostly hiking boots and casual walking shoes), kids clothing and gear, and camping supplies like sleeping bags. The products tend to be in the higher end of the price spectrum, with lots of name brands. read more
