I never leave for a ride without a pair of cycling gloves. I think it is important to protect your hands in the case of a fall. Gloves are a cheap insurance policy. Nothing is worse then picking gravel out of your hand after a crash. With the variety of sizing available everyone should own at least a pair of gloves. Gloves should be the first piece of clothing purchased, even before a pair of cycling shorts. While shorts are a key piece of clothing the safety and comfort offered by gloves shouldn’t be overlooked!
For the last year or so I have been riding with Pearl Izumi Gel-Vent Pro Gloves. These gloves are available in both a short finger version and a long finger version. I own both, the short finger version that I use for most of my road riding while I mountain bike with the long finger version in addition to using them for moderately cool road rides.
