I've been coming to this store for the past ~8 years or so. I only buy things related to hiking and camping.
They carry brands such as: outdoor research (only recently), woolrich, sierra designs, Keen, Teva, Garmot, Misty Mountain, Gerber, Canada Goose, Surefire, Innova, Smart Wool.
Pretty much a wide range of low-end brands to premium brands.
Since they started stocking Canada Goose, they now attract the under 30 crowd with money to burn. Visit during the fall/winter and you'll see what I'm talking about. Ex. Teens with their parents trying on the $600 jackets for the walk to the bus stop.
Its good for the store, they now have more customers.
They have an extensive selection of hunting/fishing gear. But I don't know much about it.
For basic camping gear, I find that this place is pretty cheap. Their Colghans stuff is quite cheap compare to Canadian Tire. I thinks its the same price or cheaper than Mountain Equipment Co-op (MEC).
They also have some membership deal where you buy a membership and get a discount. I can't remember the details, I bought the membership once, but it was a few years ago. The membership is not required to buy anything though. (Unlike MEC)
Their store hours are odd, check the website before visiting.
