Frequently Asked Questions
Q: Should I size up for arm warmers?
A: Some brands (like Castelli) run tight. Check the sizing chart carefully — snug is good, but not restrictive.
Q: Can I wear arm warmers with a short sleeve jersey?
A: Yes! That’s the main idea. Arm warmers let you adapt to changing temperatures without committing to a long-sleeve jersey.
Q: Are there waterproof arm warmers?
A: Fully waterproof? Rare. But Castelli Nano Flex and Sportful NoRain are water-resistant and great for drizzly rides.
