Quality product
Pros: Attractive, Comfortable, High Quality, Good Fit
Cons: perhaps not the warmest
"These arm warmers fit beautifully and appear to function very well in the wet. I am about 180 cms (5 ft 11 inches) tall and slim build - I purchased the mediums and they fit like a snug glove. In fact they have more of a compression feel all over compared with previous arm warmers I've owned. Last Saturday it was pretty wet on the bike, but the water just beaded off the material superbly. I did not get wet arms and did not feel clammy underneath. The nanoflex material seems to do exatly what it says it will. Probably not the warmest of arm warmers, but definitely one of the most water resistant. Well done again to Castelli...a very high quality brand."

Great
Pros: Great Value, Attractive, Comfortable, Good Fit
"These warmers are great value, perform well and look great. During the early morning i wanted an extra layer which can then be removed easily and these warmers do exactly that. I wear them up to around 17oC and they help shield from the elements and dont over heat on the climbs. They sit well just below the armpit and havnt slipped at all to date. For the value, i cant fault them"

Pros: Comfortable, High Quality, Good Fit
"These arm warmers are really comfortable and long especially compared with the DHB ones I purchased last year which came up 3-4” too short. They are a nice snug fit, they don't slip with their double sided grips which help stop the jersey from working its way up the arms. Highly recommended!"

"I have now used the castelli arms warmers in sub 10c and they have kept me warm. The fit is superb and the inside lining is what makes them comfotable as well as keeping you warm.
I chose the white colour and in my opinion they look great with a black jersey.
My concern was having the small would be no good. I am 5ft 9 and weight approx 67kg and the fit is good.
Great for use in the spring time & early mornings."

The best I've tried
Pros: Durable, Comfortable, High Quality, Good Fit
"I've tried many different types of arm warmers and these are by far the best of the bunch. Great snug fit, good siliconey bit to grip the arm near the shoulder without slipping, fleecy lining so nice and warm but best of all the nanoflex genuinely adds a bit of wet weather protection. Also, they don't lose shape after washing. I've washed mine a dozen times and they emerge as good as they went in. Very pleased!"

Very Good Arm warmers
Pros: Durable, Comfortable, High Quality, Adjustable, Lightweight, Versatile, Good Fit
Cons: Unattractive, Limited Color Choices
"Probably the best I have used. Excellent cyclists cut; cyclists often don't have massive arms - take note Assos, De Feet, Giordana. Really good length, covering the top of the arm, to the base of the hand (and I have longish arms too). They aren't waterproof as the description might lead you to believe, but in drizzle they do keep you warmer than say, a merino or wool pair would. Not as warm as a proper Roubaix warmer (i.e. Assos), but what they lack here they make up for in fit, feel and comfort, and if its that cold then just wear a L/S top...
I crashed heavilly in them too, doing damage to my elbow, which surprisingly didn't even scratch the arm warmer. Very, Very good product from Castelli."

"I expected more for the price. Expensive, not very warm, and small size. The castelli logos are made of something like vinyl, and they wear easily when you put them the first time.
They are impressed with the lycra at normal status, and when you wear the lycra stretch and the logos shows the crack."

Great for longer arms and they don't slip down!
Pros: Attractive, Comfortable, Lightweight, Good Fit
"Am very happy with these. Wore them for an 85km ride in cold, windy with constant drizzle. It wasn't until i went to take them off that i realised how well they worked at keeping my arms warm and dry. They were very damp on the outside but my arms were fine. I am 6 foot 1 and 82 kgs with long arms. The XL fits very well, snug without being too tight but perfectly long, so I can pull them right up to almost my armpit and still plenty of length to cover my wrists and leave no gaps. Also they stayed in the same position the entire ride. Very happy with these."

super quality arm warmers
Pros: Comfortable, Rugged, High Quality
Cons: little bit too long
"A brilliant set of arm warmers.
looked at a few diffrent brands and opted for these and i'am not dissapointed at all.
If l was to comment on one thing l would say they are a little bit to long but this is better than being to short!!!!
l am 6ft 6" tall and have long arms and there is still plenty to go.
As most people cost is a big issue but these are priced brilliantly and you can see the quality in these arm warmers good quality grippers"

Perfect fit and waterproof
Pros: Comfortable, Adjustable, Lightweight, Good Fit
"Perfect fit in small size for me. These warmers are also fairly waterproof and in combination with the Gabba jersey, make for a great outfit for wet rides!
The inside is lined with a soft fabric, so It's also pretty good at keeping the wind out and I've had no issues cycling by 5C with only these on my arms.
Brilliant stuff!
Durability: we'll see in the long run, but so far so good after daily use for more than a month."

Great kit
Pros: Great Value, Attractive, High Quality, Lightweight, Versatile
"Got these mainly to go with my castelli gabba jersey, but they are also very useful to go with any short sleeve for that extra warmth.
I have used these a few times now in cold and wet conditions. At first arms felt a little cold, this could be as the gabba blocks wind so well? But once on the move they had a good amount of protection even in rain. Which at first as I got the White ones thought would mark up but, they've actually been fine thanks to ability to shed water and so muck in it with it.
Sizewise found them quite long but did get the large, but they were still very tight! Almost overly tight, with medium build arms."

Castelli Nanoflex Arm Warmer 2011
Pros: Attractive, High Quality, Good Fit, warm
Cons: not as comfortable as thought
"This item is really as described, water repellant. Even when you try to wash it by hand, it doesn't absorb the water.
In terms of size, I got the Small and I would say it is quite a small fit arm warmer. I'm about 160cm and have skinny arms and it feels a bit tight fitting on me. Probably because the material is not as elastic as some other warmers I have. i.e. it doesn't stretch as much
If you have big arms, I suggest going a size up. Length is fine and the sticky band at the top being on both sides does hold the arm warmers in place. Great if you have skinny arms as some other designs can sometimes slip down."
