I was attempting to get a link for someone to MEC's Slogg Portage Bags and all I came up with is a Sealine Pro and a couple Algonquins but none of their really great bags.
Not quite yet. They still have 483 paddling gear items up for sale including kayaks and canoes. Using their search, look for "paddling and watersports gear"
Scully gear is no more apparently. They're finding it not cost effective to build much of their own stuff anymore. In many cases they're just having a large company brand that companies gear as a MEC labelled gear. Tents and clothing seem to be the only MEC designed gear these days.
I talked to staff in the local MEC tonight. All the paddle sports gear has been moved out for the winter, and what is left (clearance) is in the warehouse. But he said they are not getting out of paddle sports sales, and will have a full lineup of gear again come spring.
