About Craft Of Sweden Prowarm Shirt: Next product I’d like to show you is a product called Prowarm. Prowarm is one of our warmest base layers but don’t be fooled by that. Really the key function or feature or benefit here of Prowarm is it’s finally a very cold weather base layer you can really crank on and not overheat. As you all know sometimes the biggest challenge in the coldest degrees and working out is actually not overheating versus staying warm. What’s unique about Prowarm is I think visually you can see it’s a seamless 3D knit which means you have precision targeted insulation and ventilation zones based on if you’re a man or a woman and based on where you need insulation or where you need ventilation. Obviously here you can see that you’ve got greater insulation on the chest, shoulders and outer back area. And here along the center of the spine, under the arms and along the torso you have a thinner fabric story which is going to give you greater ventilation. What provides the warmth is actually that this fiber itself is a full hollow core fiber as well. So as you release body heat, those hollow core fibers will help trap it where you need the warmth but help release it where you want to stay cool. It’s antimicrobial. You’ll stay fresh and clean longer. It won’t stink. It comes in two styles. It will come in a full-zip, actually rather than just a zip mock it’s almost a full half-zip with a zipper garage. It will come in a crewneck, both long sleeve. The zip mock retails for $84.99 and the crewneck retails for $74.99.
