Patagonia Nano Air

It's got just your classic YKK, Bizlon zip, and yeah, all in all, for an insulation piece, I really like this jacket.

Now Spoiler Alert! I own this jacket, so I'm probably a little bit biased, but I absolutely love it.

Very versatile jacket. Yeah, very packable. It's very packable

Even if the face wets out, the water doesn't pass through all that quickly. Polyester insulation is pretty hydrophobic, the jacket has to get really wet before it gets to the wearer. I wouldn't wear it in heavy rain, but you'd stay warm in medium rain for quite awhile, so long as you could tolerate the jacket being wet. The face is pretty wind resistant, the fleece side panels are not.

Mid-layer hooded jacket, runs slightly on the slimmer side. 60g of Primaloft Gold Active insulation and Pertex Quantum Air shell. Should keep you comfortably warm down to low 40s. Use Paypal and pay using Chase Freedom card for 5% cashback.
