Be careful with the made in US only. More power to you with that, but it costs. We love our way of life here in 'Merica and it will mean a low margin for your products.
What fits your image as far as I can tell:
Do a technical flannel. Don't make beanies. Instead of block stickers, do diecuts. Make sure you have the company name with the logo. Don't do Logos in the middle of shirts. Put them on the bottom on the sides, on the sleaves, huge wrap around on the side... center is boring. For hoodies, find someone that does straight cuffs with thumb holes and order from them. If you do a tech hoodie, don't do elastic bottoms, make them fitted and just continue the body fabric and surger the end. If the fits good and you don't have elastics then you wont get frozen spots while riding. Socks are in. Do some quality socks. Don't make neck gaiters, there are already enough gaiter companies out there. Make a stretchy dark blue jean jacket that's got DWR. I want one of those.
Also, you are going to need borderline arrogance with a splash of humility and rhino skin to make it in this market. Good luck.
I threw the facemask up, the full facemasks will be up in the next few weeks.
