The SuperWarm suit series is completed with the top. In the extreme cold this is the top of tops.
The outer weather layer is Hydrophobic, the insulation layer is super stretch neoprene (you'll be amazed how stretchy this top is), the inner layers are Titanium and MicroFleece so your body heats up a super toasty super warm thermal layer. All four layers combine to make this the ultimate in technical tops.
