My husband loves them

  • Familiarity: I gave it as a gift but have feedback to share

I got these for my husband. He's 6' 150 lbs. and the medium fits him perfectly. He loves them and wears them even when I think it isn't cold enough! And they look *great*.

Not bad for the $$$$

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

I got a good end of season deal on these and used them in a Duathlon relay. Overall they worked great. One thing that I have noticed on Castelli stuff lately is that the logo starts to crack and peel off. Hate that. However the performance is still good. I have big legs and I used a XL. Fit was great.

Unanswered Question

I've never bought a pair of warmers before....

I've never bought a pair of warmers before. If I normally wear a large in castelli shorts, would the size correspond? Thanks!

Meets my needs

  • Familiarity: I've put it through the wringer

Debated between the Thermoflex and Nanoflex leg warmers and went with the Thermos. First on size I went with XL which is the same size I wear in Castelli bibshorts, tights, and jerseys. I am 6'4" and 190 lbs. I have a 34" inseam and the warmers are perfect in length. I have used these in 40 - 58 degree rides and they have provided the warmth I've needed. I have 1 pair of tights and 1 pair of knickers. So the leg warmers give me another option on colder days.

The warmers have grippers on the inside of the top and I did not experience any slippage. I would highly recommend these for someone searching for leg warmers. In conclusion they are comfy and I don't notice them when riding.

Works well

  • Familiarity: I've put it through the wringer

The leg warmers work well. I also brought the knicks, but i find myself wearing bibs and these leg warmers now, as they do the job, maybe a little better

do they come in pairs?

Do not buy

These were delivered with a tear in one of the seems. Third time out and another tear develops.

Never had problems like this with any other brand before.

Wish they would have fit

These seem like they would have been great warmer. Unfortunately the large was just a little too tight. With no extra large available I went to the Castelli Nano instead.

nice fit

I was hesitant to buy these leg warmers because of the previous review, but I tried on some Castelli leg warmers a year ago, and they were the most comfortable, form fitting thing I've ever put on my legs. I bought these leg warmers hoping they were the same ones that I tried on before. They were. They are incredibly comfortable, and they look smart. I've only worn them once, but the stitching is fine.If the stitching comes unraveled, I'll post an update. Because you can return them at any time, no questions asked, I will if the stitching doesn't last.

Nice, but stitching unravels

These kept me nice and warm, but the stitching is not bomber. The stitching on 2 pairs has come undone. Once after one ride and the other time out of the bag.
