Softgoods design...useful links?

Hi guys!

I’m currently getting into sporting goods design…particularly developing gloves, belts and everything related to this type of softgoods for gyms. I’d appreciate any advice on how to get materials, suppliers info and all related for these type of goods. Manufacturing processes and machine types info is a must know for me as well. Could anyone give me a hand with helpful links to do a deep research on this…I would appreciate any help. Thanks
