In reply to your last queries, I do NOT have …a beef…with MEC, some of those who founded it were friends of mine, but, the situation with WM is not what MEC was founded to do. However, as I posted, if one WANTS an MEC bag, great, go for it.
MEC does not stock the WM Versalite, the weight you mention is for the WM Apache and that is a GT-shelled bag, so, it is heavier….but, warmer.I have carefully examined the Merlin bags, both of them, at the MEC main store as I go there to see a friend of mine who has worked in the office for years.
I do not see these as anywhere close to WM in quality and having owned and used bags from both WM and MEC here in western/northern Canada, I seriously doubt that the function, especially over time, will be close to equal.I note a previous poster,s comments that indicate that his companion was cold in very moderate winter temps. in his Merlin, while he was warm in his WM, that should tell you something.
In backpacking/mountaineering gear, more than in almost anything I can think of, you get exactly what you pay for. MEC targets the casual, recreational users in most of their gear and that is fine, BUT, when/if a piece of gear fails you on a trip, their excellent return policy does not mean much deep in the wilderness, far from replacement.
Very simply, WM is among the roughly five finest bag manufacturers in the world, the others are FF, Integral Designs, Valandre and Peter Hutchison Designs. I own and use bags from all of these except PHD, which I probably will get a custom Hispar from later this coming winter. I also owned/used an original Marmot from the Grand Junction days, a superb bag much superior to those now offered.
I would bet my entire collection of six bags by the above makers that you would find a WM bag much superior to any MEC bag, especially over longterm or hard use. I would not do this had I not had sufficient experience with both makes and others to feel confident about the outcome…fair enough?
