Description

Warm and dry never looked so good.

If there's one failing of most legwarmers it's that they absorb water like a proverbial sponge. On rainy days they end up waterlogged and providing compromised warmth. The Castelli Nanoflex Legwarmers are perfect for riding in conditions that are both cold and wet.

Nanoflex is a proprietary Castelli fabric. The mill begins with Castelli's super-warm and ultra-stretchy Thermoflex fabric, used in many of its winter garments, and then coats the outside with ultra-tiny nanofilaments of silicone fiber. These fibers create a near waterproof barrier to moisture, and raindrops run off the fabric without soaking through. Despite its water-resistant finish, Nanoflex fabric remains highly breathable, keeping you comfortable in almost any conditions.

Silicone leg grippers keep the Nanoflex legwarmers in place even on the hardest rides, and ankle zips make them easy to get past even the largest feet. Reflective logos are printed at the knee and below the calf to help you be seen in low light.

The Castelli Nanoflex Legwarmers come in Black and in four sizes from Small through X-Large.

pretty darn good

I'm rather liking these legwarmers.
Sizing: I wasn't all to sure what size I ought to order, being a girl, but figured a Small would be appropriate. The fit is good, not perfect but not bad. It's strangely a bit tight around the calf area, I've only worn them twice but perhaps they'll stretch out a bit, because otherwise the ankle zippers get all scrunched. I don't think I would go up a size as I think the upper thigh would end up too large.
the Good: More than sufficient warmth at 40-50F. Haven't tried them for colder temps. They are definitely water resistant, pretty much waterproof. Ended up doing about 20miles in some rain and while my shorts & shoes were soaked these babies kept my legs completely dry.
the Bad: the silicone grippers can get a bit irritating. Especially when they get around the seams of the shorts. Probably would be better if they could manage a different form of band for the top portion, something like what Castelli uses for some of their shorts/bibs. They are not super stretchy, but that may be part of the water resistance aspect, so consider sizing up unless you have skinny calves.

useful item

I like these legwarmers, they are very good quality, water resistant, they stay up and the ankle zips are a plus feature lacking on other similar products. Good down to around 45F then its time to move into a warmer winter product like full thermal bib tights. Have the matching knee warmers and arm warmers too. size L in all of them is right for me/183cm tall long legs

Not comfortable

Felt rough & scratchy and the outside & uncomfortably bound at the knees due to the type of fabric

Fits nice overall, but the zipper...

The Castelli Nanoflex legwarmers contain a fleecy interior as well as a waterproof exterior. Being that these are snug, the silicone grippers do irritate my skin a little bit. This is from the friction of the grippers with my skin. Slightly uncomfortable after a long ride, but being that they feel comfortable otherwise, I don't mind too much. The irritation really sets in after these are removed. These legwarmers are a bit on the glossy side, as with the arm warmers.

Additionally, since these legwarmers (or being that Castelli products generally run smaller), the zipper digs into my ankle. I'm not sure if going a size up would make all the difference. It probably does, but oh well! I like what I have.

Good for water but

For leg warmers these are great at repelling water but only really kept me warm down to around 50 degrees. I've ridden in the rain and they definitely kept me dry but on rides that get into the 40s I definitely feel the wind slipping through the warmers. Overall I really like them but with the weather getting colder I'm going to have to use thicker leg warmers on non rainy days. These don't stretch as much as my other warmers and I had to order up a size so they would fit around my calves.

Water Be Gone

You may have seen the youtube clip with the dude holding these under the faucete and the water cascading off. I'll be honest, it was enough to get me to try em out. Last week I wore them in some REAL rain. I was really impressed with their ability to shed H20. That said, they are pretty thin so not super warm like some of the more thermal warmers I've used.

What is the unstretched: total length, circumference at the ankle and upper thigh for the various sizes? I'm 5'10" w/ a 30" inseam and a upper thigh circumference of 25". What would be the best size?
