Hello. Thank you for your contact SEMAPO GEAR
It is one of narrower vest. Actually NJPC is lighter, but some people just do not like the shape. It is personal choice issue.
MMAC has narrower for front panel which makes more comfortable and gives movement on shoulder.
So you have to use 'swimmer's cut' SAPI plate which is narrower than normal SAPI plate.
Please contact us at anytime if you have any questions. We will gladly answer you.
Best regards

I'm looking for a high speed, low drag vest. Is the MMAC a good choice for this? IE: tight around the waist and shoulders.
