Hi, I'm 5'6" 150 lbs. I purchased a vulkan A1 summerweave gi. The new vulkan seems a little tight around my chest area, and the collar is rubbing against my kneck. I'm pretty new to bjj and I don't really know if this gi is too tight or just right. I am currently wearing an atama A2 singleweave. Anyways I've got class next week which I'll bring the gi and see what my instructor thinks, but for now I'll ask you guys. Thanks for any help.
