All condition kneewarmers
Water repellant Nano Flex technology keeps you dry and warm

Very Dark

When I opened the package I thought "these are not right, as in black, not blue". So much so I contacted CS and had an echat to confirm. I was ably helped and assured they are very dark but was given a RA# if I wanted to return but even better got a discount if I wanted to keep.
I find them to shift towards dark blue with my navy blue shorts and work fine with the kit. They are longer than my other Castelli Nano Flex knee warmers which is great and they fit more snugly so no creeping up and bunching behind my knees.
I am very happy with these knee warmers.

Knee warmers that do their job

I live in Los Angeles, so it's only been cold enough to wear these once. Tough life, I know! They generally stay up - just had to pull them up once during a 60 mile ride.
I didn't give 5 stars because as I putting them on, I could hear some seams popping, which causes some concern as to their longevity. Will certainly provide updates as I get a few more uses out of them

Extended length and silicone grippers on both sides to ensure they stay put.

I wear these with standard bib shorts and the extra coverage on colder days is great for staying warm. The tops have grippers on the inside next to your skin and outside next to the shorts so they stay put.
