First of all let me start by saying I'm an Arctery'x fiend. I own the Sidewinder SV, Gamma SV Jacket and Bibs, Gamma MX, Bravo Pant and Jacket, Alpha Jacket and Pants, Chiamera Shirt, and Cam SV glove. All have been purchased from reliable vendors or the LEAF program directly.
I'll echo what Alpinist said by seconding the FR need. I think going in a Merino wool direction would be interesting.
Also I wouldn't mind seeing equipment made by Arctery'x. It would be very cool to be the first kid on the block with a Chest Plate made by you folks.
I think Arctery'x is poised to be one of the only companies that can compete directly with the quality of companies like Crye Precision, and since they are diversifying into the garment world more heavily, I think it would benefit you to do the same into the gear industry.
As a voracious consumer of your products, I would be happy to demo or test anything you have to offer.
