hahaha..you're another one of those anti-trend retards...Well for your info I have a onepiece and it is the warmest, most comfortable, steeziest piece of clothing that has ever had the privelege of touching my body. Also I have only seen one other person on the mountain wearing one in my 40+ days skiing this year, so i wouldnt really consider it trendy.
   As far as it not being practical, i highly disagree. One-pieces are without a doubt alot more practical than a jacket and pants while skiing. warmer, more comfortable, and snow never goes down your pants when you fall.
  Also, I dont think its really a big deal to have another jacket to wear around? I dont particularily like wearing a ski/snowboard type jacket with my street clothes anyway, so i have a different jacket that i dont wear skiing.I know you think you're super cool because you are "different" or "anti-trend", but you're arguments have no validity.
