Grumman Down Jacket

It was recommended to size up to the XL and that fit perfectly. I wear a large in all things stone glacier. I'm 195 - 6'1" and athletic / lean. Hope this helps others for sizing. Regarding the warmth, these are amazing. I layered up my gear (also stone glacier) and put these on over all of that. I sat in -10 and just waited for 30 minutes. I did not feel any cold creeping in and could have sat there a very long time even with wind. This is exactly what I was looking for. Thank you SG and team!

Love this puffy! It will be perfect for Wilderness Elk Hunts in cold weather as packs up small, weighs virtually nothing and WARM!

Excellent jacket, high quality materials and craftsmanship. This coat is by far the warmest coat I have and is as light as a feather. If warmth and wait matter to you, this is the code to purchase. I highly recommend this jacket. As a field going while a biologist I spend over 300 days a year in the field. I found this coat to be excellent for warmth and durability.
