A bit too wide

For pretty much everything else I wear Castelli L(arge) size (bibs, jersey, jackets, etc) so I thought I should get an L for the arm warmers too (it doesn't help that Castelli does not publish a sizing guide that considers hand length/circumference). Well, that was wrong, the L warmer barely sits on my hand, it's probably not going to slip on its own but it doesn't feel like it sits firmly on the hand either. Next time I'll get an M...

The other problem is that some of the stitching has already started to come off after 3 wash cycles (I use the lightest setting on the washing machine for bike clothing). I think my cheaper Pearl Izumi warmers held longer.

Thank you for your feedback.

Great arm weather for cold, wet conditions.

Works great on cold days, and especially with a light rain where it keeps the arms pretty dry. Was a great combination with my Castelli Perfetto RoS Light Jersey while cycle touring with several chilly days with a drizzle and light rain.

Thank you for your feedback.

Excellent product

I'm in love w these arm warmers. Can I marry them?!? Maybe I can get a marriage tax break!!

All fooling aside, I love these things. They are super warm and super comfy. They have excellent grip so I've never had a problem w them sliding down. Not even a little. I would definitely buy again if they ever wear out. Good luck on them doing so. Or buy as a gift. Make an amazing gift. I bought these With my own money for myself for cool MN rides in late fall. I seriously would not even look at another brand. Simply amazing!

Thank you for your feedback.

So far quite good at a reasonable price

I've used these in damp weather (including with a short sleeved jersey under a winter jersey) into the high 30s; so far I've not used them alone in rain so I can't speak to the reputed water resistance. They fit well, stay up, and are warmer than others I've had-the fleece inside is great.

Thank you for your feedback.
