Sherwood has Small, Med, Large, and X-Large....
Zeagle has the same sizing, but shoulder and waist are sized seperately and put together to give you a better fit.... for example, I wear a Med Shoulder / Large Waist. I have a Zeagle Tech BC and absolutly love it... I had a pocket sewn on the right side so its kinda like a Ranger. Plus Zeagle guarantees their BCs for life... you can drag em home by a rope and their customer service won't blink at repairing / replacing. Get your goal BC now... see if the shop will do layaway for you.
Good luck
