You need to get out there and look around and try things on. Different helmets fit different heads. All clothing is not cut the same, one company's large may be X-Large in another company. All goggles don't fit the same.
Boots are a whole different story. You need to find a Great Boot Fitter and spend time getting the right boot for you. Have you not heard, "Boots are the most important part".
Most shops start having sales in the next couple weeks. Start with finding a great boot fitter. See what his shop has for other items you need. Build a relationship with the boot fitter and his shop. The pay back in the long run is priceless.
