A leg up.

Castelli's original Nanoflex warmers were a revolution in water-shedding technology, and now they've made them more compact and more comfortable than ever with this Nanoflex Plus version. It offers the same amount of protection from rain and road-spray, but its multi-panel design uses thinner Nano Light fabric out back for better stretch and breathability so you don't have to hold anything back when the going gets tough.

Features double-sided silicone grippers at the thighs and zippered openings at the ankles. Claimed weight is 136 g / pair.

This replaces my cycling tights. I wear legwarmers in the morning when its chilly and take them off when it warms up. On morning I got caught in the rain. The Nanoflex plus coating really works. The rain just shed off. It wasn't waterproof, but, it shed about 90 percent of the rain. It kept my legs dry and warm. New technology, I'm impressed. I'm really happy with this product.

warm down into the high 30Fs, without being too constrictive or thick

The fit is excellent. I'm 6'5 & 210lbs, w 34 inseam. Long enough that I can pull them up quite high and they still cover to midway between ankle and bottom of calf. Paired with above ankle sock/shoe covers, these keep the warmth in. The silicon gripper at the top works well. It's not overly wide (like Pearl Izumi). Also, the zipper seems more robust than some of the other brands I've tried. These are my go-to pair in all but the coldest temps (I have a thicker pair - forget the brand) for I've ridden these in temps into the mid 30's, and once I get my body temp up, they keep me warm. They are also moderately water repellant in light rains.

Warm and tough leg warmers fit perfectly with zero sag.
by DannyG

I'm a former cyclocross racer and came to hate leg warmers, due to their stubborn tendency to sag and droop, particularly when wet or muddy. I'd typically opt for embrocation on bare legs, even in the coldest weather. Now that I no longer race, I've lost a lot of that toughness and prefer to cover my legs when cold, but I still can't stand the sagging of most leg and knee warmers. I also find they get threadbare at the knees after only a few long rides. These are different. Thinner, non-roubaix fabric on the back of the leg (which doesn't really need wind-proofing), and tough, thick roubaix fabric on front. All-black fabric has worn extremely well so far. Also dig the gripper bands on both inside and outside. Helps keep things tidy. If you're not a fan of tights (like me), pair these with a good thermal bib short (like Rapha). Good to go.

Best out there, blocks everything.

Everything you want in a leg warmer. Fits great, not short, not too high. Sheds water like a windshield. Warm and blocks wind. Would say, as others have in the past, many washes may make the logo peel off. But no big deal.

I am 6'1 about 160, with skinny legs and a large fits great.
