MEC Northern Lite jacket replacement?

Edit: ok perhaps not 15C but not much lower :)

I hear you. That was an awesome jacket. I still have the heavier, 3 oz one, but my uncle had the one you’re talking about. When it finally had too many holes to look respectable, he turned it inside out. We both made the Kinsman insulated pullover kit from thru-hiker.com, but they no longer sell 1.8 oz Primaloft. In fact, I haven’t seen 1.8 oz Primaloft much lately, which makes me think it’s not very popular anymore. If you are open to making one, the kit itself is pretty great. The arms are baggy, but it allows you to pull your arms inside the jacket, which is handy. The Rainshed sells 1.8 oz Primaloft, but you would have to find a pattern.

Take a look at the newer breathable insulated jackets like the OR  Ascendant and Nano Air. I’ve been using the older OR Superlayer jacket which is much like the Ascendant with different insulation. It is great in the cool wet/humid conditions in the PNW. Like a fleece, it needs a shell when the wind picks up.

The new Micro Puff is a pretty close replacement.

I bought an Arc’teryx Atom LT , of course we need more seasons to see how well it will work but so far, under a North Face Dryzzle it kept me real warm and it’s a real nice feeling jacket.
