Very light and warm.

This jacket is very well made, with durable materials and its many pockets. It is much warmer than its lightweight construction would suggest. It puts the many other puffer jackets on the market to shame. You will not be disappointed with this jacket. It’s so lightweight you can pack it for any trip. It packs away easily in its interior pocket bag and can just be clipped onto a pack. I love the way it fits and it is true to size, for reference I am a size 10-12 US and the large is very comfortable for layering with the adjustable elastic. I have wide shoulders so if your build is narrower you would probably fit a medium comfortably.

cutting for the chest is a little wide so flexing arms forward requires pulling up the sleeves a bit. wish it was delivered on time so I could properly test it out on my trip but alas it's gonna have to wait for a proper test.

I’ve had a chance to wear the jacket out on cold days and pleased with how warm it kept me. And I was really surprised at how light the jacket was. Like when I received the package I actually could not tell if there was anything in there. The placements of the pockets (especially the ones inside) are great in carrying around my valuables. Only time will tell if the jacket holds up but for now very happy with backing the Kickstarter project and another solid product from Seadon.
