CRAFT ZERO EXTREME LAYER 1 Have you ever found yourself looking for something between a short sleeve and a long sleeve shirt? You know when the temperature is warm but you still want your arms covered? ZERO EXTREME fits nicely in this sector. This piece is so light weight and breathable that I was nervous to wash it the first time.   I thought it would fray or fall apart. Now after numerous washings it looks and feels good as new. I have taken this piece to the wet and rainy areas of Seattle and used it under a waterproof shell. I trained in it regularly in the Utah under a jacket for very cold snowy temperatures. I have also taken it to the Grand Canyon for the early morning decent starting the R2R2R. This layer goes great under a shell biking or by itself under a hydration pack or just solo. The ZERO EXTREME is the most unique base layer I have ever used. But why? The FLY AWAY moving wing technology gives ultimate flexibility and movement in the upper back shoulder to shoulder. This section of mesh is great for ventilation. I particularly like the feel of the garment running. There is no bunching under the armpits, and there is no extra fabric floating in the wind. The construction of this garment is ideal for larger shoulders and a slimming waistline. So many shirts have a straight cut so if it fits snug the seams will dig into the shoulders and upper back. CRAFT has nailed the ergonomic feel that athletes need from a base layer. CRAFT is putting this technology into several pieces. Check it out at www.craft-usa.com.
