Our Favorite Fitness Products of 2014

Fall workouts outside can be tricky. It's too hot for long sleeves but too cold to sport your tank top. Whether running or biking, I'm a huge fan of these Bontrager Thermal Arm Warmers ($35). The fabric is soft and durable, and it wicks sweat so I feel completely dry. My other favorite feature is the silicone lining around the inner elastic band on the upper arm. These stay put until I pull them off, without having to mess with them. They keep me warm for the first part of my workout, but they easily slip off when things start to heat up. If you're not a fan of plain-old black, increase your visibility to others by ordering red or white.
