PEARL iZUMi  Sun Knees

Expected a longer lasting product from Pearl. After three uses fabric is showing significant wear and doesn't look like it will make it through an entire season. Feeling very let down with this one. Look elsewhere or just order knock off brands. Expected more from a brand name and a product sold by REI

This new design simply does not perform. The fabric feels flimsy. They do not hold shape while pedaling - Two pedal strokes and you have a flimsy wrinkled mess. My original Pearl Izumi Sun knees lasted for many years and held their shape while pedaling. i'm returning this new version and going with a different brand.

I like that the Sun Knees are fairly light material as fitting this close to your leg can make it hot, but these aren't overbearing. The fit seems pretty true to the sizing chart.

These Sun Knees really block the sun on hot sunny days, but do not make my legs hot while riding my bike. Most recently I have worn them on a 2 and 1/2 month ride across the country and they have held up. After all this wear they still do not slip down. Size small works fine for me- 5'1"; 108 lbs. Comfortable too.

Overall, these work great at what they're meant to do - keeping the sun off your knees and calves. The upper leg part feels like it comes up a bit high on the thigh, but they may be more likely to slip down if they came up lower. I'm 176 lbs and the medium initially seemed too big, but they actually fit quite well and allow for free movement without getting bunched up. Word of advice - put your bike shorts on first and then the llegs Also, if you wear crew length socks these will completely cover your legs!

Bit shorter than the original sun knees. Comfortable on long rides and keeps the sun off.

For the record, I would never wear knee sleeves if I didn't have to and dreaded needing to make the purchase and transition into making them a normal part of my cycling kit. I have an autoimmune disease that causes vasculitis in my legs exacerbated by sun and heat. These knee sleeves keep me riding beyond mornings and for long durations in the sun/summer. They are warmer than wearing nothing on your legs, but not exceptionally so. They do not pinch or restrict movement. Glad I found a solution other than not cycling in the sun.

Purchased my usual size medium and they ended up bunching-up after a few pedal strokes. I wrote a review and I was contacted by a rep who suggested I try a small and even gave me a great discount. I returned the medium and purchased the small. The fit is correct, but same problem - They become a wrinkled up mess during the ride. The fabric seems thinner than the original. My arm coolers in the new fabric are great. The rep was very helpful, but these new knee coolers just aren’t as good imho.

Comfortable and yet protective of UV rays on long rides. I would recommend this to cyclists who are out exercising in the heat of the day for 30 minutes or longer.

I’m 5’3” and 118lb female with “skinny” legs and the XS fits perfectly. I did use the measurement guidelines to find my size. It is labeled as black but it’s a dark blue in color. The elastic is black and the rest of the material is a dark blue and it’s obvious. Not a big deal for me though, but I’d be frustrated if I needed black. It is light weight and breathable. Not much compression which is what I preferred but stays in place. It hits mid calf in length. Would order again.
