I have put your Alpha through substantial personal testing including surviving long distance runs, 2 ski trips, and a hike on the Appalachian Trail among other journeys. The Appalachian trail with your jacket and a hammock had me 7lbs lighter than my fellow hikers who had tents and heavier jackets. This made a huge difference where every ounce/gram counts.

A few weeks ago I wore the Graphene-X jacket during Medicane Ianos - a beaufort 12 storm in Greece - as I had to abandon my (moored) boat to seek shelter. The 20 minutes exposure got me completely soaked like I have never been before Except for the parts of me covered by the jacket - they were bone dry. Wow, what a piece of equipment!!

I received the Omega Pants with the Mid-layer jacket today. This was a huge clothing purchase. I was operating on faith; believing in the story and the reviews. I am a hardware and system design engineer; I also love the outdoors and have spent a lot of time wearing Adventure/Outdoor focused clothing, simply because of the performance and durability. The products from Graphene-X meet and exceed my expectations. These pants are Next-Level in Every Single Way. Very glad I have a non-convertible pair coming in April/May, and the fit for both the XL-jacket and L-Pants is v.close to perfect for me!!! (I was so nervous) You are hitting it out of the park. 

The GRAnaREC has become my favorite. I can and do wear it inside the house. It is so light, that it doesn't feel like I have a jacket on. I wear a T-shirt underneath, and that is all I need. I never thought of wearing a thin long sleeve top underneath until it was mentioned here (will try it for moisture management). My armpits do get warm when walking about in the Mall. The jacket might be too warm for jogging outside. I have worn it in temperatures from 7* C down to -10* C for daily walks. If it gets colder, I would add another layer (a thicker windbreaker or gortex layer) on top. I don't use the hood at all, and I hardly notice it there in the collar. I am 5' 10", 160 lbs, 33 waist, wear large sized T-shirts and the medium jacket is a perfect fit. I like that it has some give, should I gain more weight through these Covid times.
