which one???

alex, dont know what your water temps are like but i've gotten away with using a mares instinct camo 5.5 suit-but i also had on a 3-2 mm mercury shortie and a 3 mm vest underneath and our water is about 45 degrees farenheight here in oregon,USA Pacific Ocean. now the way i see it, that would be less neoprene than a 7 mm suit in farmer john style and my core stayed toasty warm. so you might be able to just use a vest under a 5.5 mm jacket and still come out ok or even better than a 7mm mares jacket. anyway just my own experience so far. good luck--mares neoprene is super soft and stretchy, very comfortable stuff. the trick is to make sure it all fits just right! have a good day!---steve
