Choose from a selection of Tri World-approved arm warmers to help you stay warm, dry, visible and fully ventilated as the weather cools down
Pearl Izumi PRO Leader Arm Warmer, £29.99
These arm warmers are a classy piece of kit that can be worn on the bike or run. The combination of aero panels and Thermal Lite fabric make them effective and fast.
On a long run in conditions that ranged from cold and windy to hot and showery, the sleeves worked beautifully throughout. They stayed put, thanks to the elasticised grippers, and kept arms warm and comfortable. After a brief downpour, they dried quickly too.
Our tester's only minor quibble was that they gripped so well they were a little hard to roll down when the sun came out. On the bike they were equally effective, and the silicone on the upper arms gripped well on the move. These sleeves look and feel really premium and do a terrific job.
