Indeed. I loved stopping in and browsing around when I was in that area. To be honest, I had thought Paramo had moved further away, outside the convenient tube network, but I checked the map and it is very doable in the same day, just not so easy for a quick look in.
While I love my Paramo gear, they are expensive and really only do clothes. For someone starting out their gear can be a steep investment.
All my bits came from the 2nd sales that they did near to Nikwax factory. Think that's all moved onto ebay now.
