5'4" 160 and falling. I tried on the ninja sumo at a local shop and found the medium and small both fit...but the small fit legthwise the best with legs and sleeves....Obviously I'm a small guy, but by no means a skinny dude. Been dropping lbs. for about two years now and I think I'm almost done. Unsure weather to go with the small or medium...Since the standard ninja is a more athletic fit, I'm not totally sure if the small will work as it did with the sumo ninja.
Since the Sumo and Merino both have similar fits (the Merino is by no means skin tight), here is what I suggest. Go try on a sumo again at your local shop - but here's the key. See how it fits when you sit down. I say this because I had a ninja that fit fine when I was standing, but gave me a wedgie when I sat down. If you're wedgie free with the small, then go with the small. Get a wedge and you know to size up.
