Tutto Nano Tight

Winter tights can be limiting. Thick fleece and wind-proof panels trap in heat, but when the weather is in the in-between temperatures, they are overkill, meanwhile your shorts just aren't enough. Castelli strikes a balance with the Tutto Nano Tights that are built to excel in all conditions, from frosty morning starts, to balmy afternoon jaunts that bring you into cool fall evenings. They're built from the new Nano Flex 3G fabric that offers a soft fleecy lining ideal for trapping heat when temps range from the low 40's to low 60's (Fahrenheit), with rain protection that keeps showers at bay when you're hammering out the miles and get hit with a mid-day drizzle.

Castelli crafts the Tutto Nano Tights with comfort in mind, reducing seams to reduce potential for chaffing, while still keeping panels strategic to wrap around your muscles supportively. Castelli's KISS Air2 Donna chamois is employed at the seat to absorb jarring vibrations and encounters with rough road conditions thanks to its multi-density construction. A seamless skin care layer offers Castelli's softest next-to-skin fabric for comfort against your most sensitive anatomy, while variable thickness foam is used to provide maximum support to the ischial zone, tapering to moderate support under the perineum to help prevent pain and fatigue before you're ready to call it a day. The tights are finished off with a zipper at the cuffs for easy on-and-off, and large reflective band at the ankle, helping boost your low-light visibility.

I love these tights. They are warm and fit well, chamois is fine. I ride in all weather. 100 miles a week. 122 lbs, 5´7”, thin build- purchased a small.

Sizing is off

I returned this product before using it
Size Bought:
5' 3"

I have worn castelli in the past and have found the products to be pretty comfortable and they make a great chamois. Ultimately I decided not to keep these pants for two reasons. 1. I am now between sizes for castelli and wasn't sure going to small from a medium would fit my larger thighs, but the medium waist band was too big and when I bent over it slid down. 2. My last pair few pairs of castelli shorts and pants have shown more wear and tear on the seems around the chamois and inner thigh compared to other brands of stuff I have. So I returned these and kept the Giodana silver line tights instead.

Impressed with these

I've used it several times
Size Bought:
5' 2"

I am quite impressed with these. They fit great and I am only 5'2". I do have to pull up the excess length when I first put them on, but it works fine. I had a pair from Garneu and I loved them, but they have articulated knees and since my legs are short, the articulated knees would sag below my knees. LOL So these work better because they are more like tights instead of pants. I am very muscular and thick, not skinny. XL is the size I purchased, but I could have gotten by with a Large. I am hoping they don't stretch. I just wash them (NO FABRIC SOFTENER) and lay them out to dry. I have worn them in the rain and it does not soak through which is wonderful. I ride in all weather conditions and although they are listed for temps as low as 39, if you are cold natured, I would not recommend that cold. I am a warm natured person, and my thighs got pretty cold at 34 degrees. I made it work and it was fine, but any colder and it would not work for more than a hour outside. For cold and rain, they are perfect and I highly recommend.

Great cycling pants

Size Bought:
5' 9.5"

I bought this in a medium as my other castelli cycling pants ran somewhat small, and medium was perfect. Nice fit and material, seems like it will offer more warmth and weather protection than another pair I purchased, and I like the reflective bands at the bottom.

Perfect tights

I've used it several times
Size Bought:
5' 7"

Works well from 35-55 degrees F. Great fit and feel. I prefer tights to bib tights so I'm very satisfied with these. The usual Castelli high quality.
