The v-neck t-shirt with tie hem Diporto is made of Quick Dry Knit, a light mesh fabric with a Polygiene® finish. Polygiene® permanent odor control stops growth of odor-causing bacteria on fabrics, so you can wear it more and wash it less. It is our most fast-drying fabric. You can tie a knot at front, which can give you a more fashionable look while remaining useful for your outdoor activities. These features make this top versatile, great for hiking, travel and various outdoor activities. Made from GRS-certified recycled polyester.
