This 'heat suit' will allow for heat training even in quite cool conditions. However, it <table style="margin: 0px 10%; border: 1px solid #aaa; border-left: 10px solid #a00000; background: #fbfbfb;"><tr><td class="mbox-image"> [[File:Ambox warning pn.svg|42px]]<td class="mbox-text"><div>This heat suit works by preventing the body cooling itself, so it increases the risk of heat stroke. If you overheat wearing this heat suit, you will may not cool off after you collapse. Please be careful taking this approach, and start off with very low intensity exercise. Please be careful, as I've had some close calls using this technique and it is dangerous. </div></table>The key to the Fellrnr Heat Suit comes from two waterproof layers. A traditional sweat suit uses a single waterproof layer to trap your sweat and preventing it from cooling your body. The problem with the single layer is that the sweat soaks through any clothing and reduces the insulation. In cooler conditions the sweat soaked clothes can become chilly even with the waterproof layer. The Fellrnr Heat Suit approach traps the sweat away from the insulation layer, preventing this cooling effect. The Fellrnr Heat Suit has the following layers over both your top and legs.{| class="wikitable" |- valign="top"|[[File:* HeatSuit1.JPG|none|thumb|x300px|A close fitting thermal layer near the skin. The purpose of this layer is to hold the sweat and keep your skin relatively comfortable. I wear a Halo hat to prevent the sweat getting in my eyes, plus a thin hat to prevent the waterproof hood sticking to my ears.]]* |[[File:HeatSuit2.JPG|none|thumb|x300px|A waterproof layer that traps the sweat in the first thermal layer.Ideally this should be a non-breathable waterproof layer.]]* |[[File:HeatSuit3.JPG|none|thumb|x300px|An insulation layer, such as fleece that prevents any heat escaping.
