Castelli Thermoflex Arm Warmer Reviews:

Positive Reviews:

Wore these on a cool (low 50s), damp, and very windy ride and my arms felt comfortable--they neither got too hot through a hard effort nor did they get chilled. Simply perfect. I have long sleeved jerseys but the arm warmers extend the use of my short sleeved jerseys deeper into the year.
I normally wear mediums in Castelli but I have the usual cyclist's noodle arms and so bought these in a small and am glad I did. The warmer stayed put on my arm--no tugging or adjusting on the ride was required at all. The gripper was not too tight. They are oh-so-slightly longer than I needed, so the small can fit someone who is average height.

Not much you can say about an arm warmer that does it's job, which these definitely do. They may seem a touch thin, but they are very effective; though they tend to run a bit long. I bought a pair of XL's based on some reviews, but they were way too long; I'm 6', w/ average length arms, I guess - not a knuckle dragger. So I exchanged them for the L, and while they are still just a pinch too long, it's not enough to warrant a return, and risking the mediums being too short. They fit snug and seem not to want to creep down at all. Plus, red is rad.

These are great warmers. Not too expensive and easy to get on and off. Just make sure to get the right size they do run on the smaller side. My cycling club uses these castelli's and i love them. I would recommend buying these.

Nothing earth shattering about a pair of arm warmers, but they fit nice because of the bend in their design. Worn them once and they worked fine on a 50 degree morning.

Castelli stuff is always pretty fashionable and durable - I love the look of these with the Castelli logo on the wrists and they've worn very well, however a large is extremely snug on my muscular but not huge arms. I'm 6"3" and a lean 175 pounds. They are snug enough that the seams have left marks in my skin for hours after I've removed them and they've even caused some nerve interference in my left bicep. Who knows, maybe I'm just getting old.
