Amazing jacket!

"The fit and materials are amazing! I had a non-LEAF Atom previously, and just the minor details and differences over the standard Atom make this a worthy purchase!"

Great lightweight thermal jacket

"I have been wearing the Arc'terx Leaf Atom Hoody Lt (2. 1) from U. S. Elite for a couple of weeks and I find it surprisingly warm and windproof at least down to 45 degrees in San Antonio. I also wore it indoors while shopping and I got warm but it vented perspiration well. Thanks for a great product from a great company. Lt Col Tom Zazeckis, USAF (ret)"
