This armor is geared more towards a bigger person. I got my armor from trooper gear. All of the armor parts have a good amount of extra ABS for the bigger body. I'm approx 210 Ibs and have some chunk in the middle and the armor worked out great. You are about 5 inches taller than me. I'm thinking you should be fine with this armor...
Anybody can do this if they take their time and read through this forum for help, instruction, and advise......
