Z-Tech Long Sleeve Shirt (if you could just buy one thing!)

Z-Tech HydroFleece® shirts were designed by racers for aerobic activity in all conditions & seasons. They're highly breathable, super-light, and made entirely of 4-way patented Polartec® Power Stretch® that remains warm when wet, dries quickly, and is uniquely itch-free even when sweating. You'll never be without it again. If you could just buy one thing buy this.

Proprietary construction gives durable smooth outer layer that is wind and abrasion resistant but encourages evaporation. Extremely soft inner layer pulls moisture away from skin to keep you dry and comfy. Stuff one into your gear bag just in case. Pair them with Z-Tech HydroFleece® pants and beanie. Great for hiking, skiing, skating, running, biking, paddling, and especially sailing. Machine washable. Free Shipping within USA.
