I’m amazed at how well this piece works. I’ve bought two of them and probably made three other buy it and they all agree
I've been on the hunt for a touring puffy for a while now and the Aero Pullover is what I ended up going with. As someone who prioritizes weight savings and packability, this checks both of those boxes. I opted for the anorak option over the full-zip because I spend a lot of time filming in the backcountry and having an easy-access kangaroo pouch for batteries has been elite! If you're looking for a UL layer to pair with a shell I couldn't recommend this one more. For size reference, I'm 5'9 160lbs and have been in the Medium. If you're similar to my size, and like more of a loose fit, you could probably go up to a large and be happy. That said, the Medium has been perfect for me.
There's no doubt that when needed, a hood can really save the day. However, most of the time you really don't need one. The sans hood design is one of my favorite aspects of this piece - it keeps your neck warm and moving freely at the same time. That and the kangaroo pocket for keeping either a GoPro, a snack, or your hands warm. It's also super light for synthetic piece. I love down, but synthetic is nice not having to worry about it compromising when its wet and it doesn't compress, making for a perfect pillow when packed in it's stuff-sack. I'm just under 6'1" and the large seems like an ideal insulator fit. Of note, the pullover style makes it a little bit harder to get on and off.
Thanks for the review, Vic!
