Livingston is a sweet hoodie made by a great brand. I think what you guys are doing is awesome, keep it going!
I'm 6' 185lb, and the L fits me perfectly. Slightly roomy, cozy fit. To compare, I have a size medium MH summit grid, and it's just too small in the arms and torso length. I chose this over the Hawksbill for the reversed grid mesh. Grid on the inside should keep you warmer. Fleece is only there to trap warm air. Scuba neck is also pretty sweet!
