Merino wool is soft to the touch and prevents overheating even during hot summer days, maintaining its properties even when sweating. Silicone tape all around the entire lower perimeter keeps the jersey in place, and 3 back pockets provide plenty of room for snacks and small valuables. Complete with one-way YKK�NATULON� zipper and reflective logos. We used leftover materials from previous seasons, including zippers and silicone tapes, to make this jersey an extremely environmentally friendly piece.
