High-quality Zorrel t-shirts for men and Next Level t-shirts for women are distributed at the Blue Crab Bolt 10K Trail Running Series. The Zorrel Z100 men’s tees have a cotton feel and microfiber Dri-Balance Lifestyle Moisture Transport Technology. The Next Level ‘boyfriend’ women’s tees are a 100% super soft combed 4.3 oz cotton jersey with a slim fashion fit, a longer length, and longer sleeves, like your boyfriend's old t-shirt but with a fit for women. Any racer may order either the men’s tee or the women’s tee. All racers that register at least 10 days before the event are guaranteed a t-shirt in their specified size. In an attempt to predict racer participation, we will order some additional t-shirts. However, those registering within 10 days of the event will receive t-shirts while supplies last.
