MEC in Canada has the same problem. Sometime around when their logo changed from the mountains to a modern box with "MEC" written in it they stopped stocking as much high quality gear and much of their in house stuff saw a decline in durability/functionality in the name of fashion. Although speaking to people who work there they had solid market research showing that the old audience of hardcore outdoorspeople would no longer be enough to support them as it was shrinking fairly rapidly.
These days I mostly stick to Arc'teryx outers/shells, Patagonia for my mid layers, and icebreaker for baselayers. All of my gear from any of those companies has proven to be reliable and durable if pricey. I've heard good things about Peak Performance and Rab as well, but I've yet to purchase anything from them.
Edit: since this is now the recommend brands that are good but people maybe haven't heard of thread, I'd also like to plug Hestra, Fjallraven, and Osprey Packs
