The best mountain bike jersey for hot conditions.
On hot and humid days, you need an MTB jersey that works as hard as you do. The Flexair Delta™ Jersey improves riding during the warmer months using Polartec® Delta™ fabric - an innovative fabric that acts like mini radiators to keep you cooler, drier, and comfortable. The jersey has a contoured fit with 4-way stretch for maximum mobility. A densely knitted sleeve provides abrasion resistance in key areas, making the Flexair Delta one of the most versatile jerseys in our line.
