Summer gear is a system problem disguised as a shopping problem. Buy pieces one at a time without a plan and you end up with a drawer of compromises; buy them as a kit and each piece covers another's weakness. This roundup works through the warm-weather kit by role — hands, core, and the outer layer you mostly won't wear — with the combinations that experienced riders settle on.
The Core Piece: A Leather Vest
If summer riding has a uniform, it is the leather vest. It blocks wind-blast on the morning leg, covers your core from sun all day, carries wallet and phone in real pockets, and adds nothing to the heat equation that open arms don't immediately solve. The USA-made vest collection runs from minimal club cuts to pocket-rich touring vests; for peak summer, favor lighter hides and open side-lacing, which vents the torso the way a gauntlet cuff never can.
For riders who want the most heat-resistant hide in the building, the BECK 566 horsehide vest brings jacket-grade durability in vest form — dense, weather-shrugging leather that will outlast every other piece of the kit.
The Hands: Thin Deerskin, Always
Every summer kit converges on the same handwear answer: thin, unlined, breathable deerskin. A short wrist cut vents at the wrist and slips on and off a dozen times a day without complaint; the fingerless deerskin glove is the escalation for triple-digit days and city work. Either way the hide manages sweat on its own, dries soft overnight, and improves grip when damp — the three traits that make leather the summer material rather than the winter one.
The Jacket: Still in the Kit, Just Not on Your Back
Summer doesn't retire the jacket; it reassigns it. A leather jacket rides strapped to the sissy bar or bungeed to the pillion until the elevation climbs, the sun drops, or the forecast lies — then it is the most valuable thing you packed. Mountain descents at dusk run 25 degrees colder than the valley floor you left, and a summer thunderstorm at 65 mph is a cold-weather event no matter what the calendar says. The rule among long-haul riders is simple: the jacket comes along, decides its own schedule, and is always right.
Putting the Kit Together
The full warm-weather system, assembled: wicking base layer; leather vest as the constant; thin deerskin gloves — short wrist as the default, fingerless for the worst heat; jacket packed, not worn; and water carried like it matters, because it does. Total weight on your body stays minimal, total capability covers everything from a 60-degree dawn to a 100-degree afternoon and back down through a mountain dusk.
Where to Start
If you are building from zero: gloves first from the glove collection, vest second, and the rest as your rides stretch. Every piece above is leather chosen for heat rather than in spite of it — and all of it is built to be still in service when your current bike is two bikes ago.
