anyoen have the zeta 3 or zeta 3 type L in like the tri state area? preferably nj

i really wanna see how the sizing goes on them

im a big guy at times and then there are some times when im super skinny
i gain and loose weight at like a super fast rate so i just wanna see how much room im gonna have to play with on my "fat" months

right now i weigh about 200 pounds and im 6'4 ive weighed as little as 198 lb and ive weighed as much as 285 lb (i dont exspect to fit in them at that time)

any input would be great!!!
