We have a chicco keyfit 30 with the adapter for the uppababy cruz. Its a great combo but the chicco shade is too small for sunny days and annoying to move around. This thing is great, it clips around the stroller and is just snug enough on the keyfit shade so you can easily adjust it from a little extra shade to complete shade. We've brought it to the beach and lots of sunny walks. We even used it in a little sun shower and it blocked the rain a little bit. The fabric is kind of like a very loose stretchy synthetic yoga pant. We keep it with us all the time.
Also we used it at night to cover the carseat during drives when the lights are too bright for baby.

This is great. Very versatile. It fits pretty much any seat. Even if it doesn't fit perfectly you can easily rig it to fit. I bought it for my 2 yr old nephew to use while he is in his bike seat that sits on the rear rack of a bicycle. The sun rays make him irritable so I got this as a solution. It's so versatile that you can angle it to block the sun in any way. It has stretchy belts that you can tie and buckle around the bottom of the seat. Use clamps to hold it up when there is no sun. Easy on and off and packable which has its own pouch. It is like those round sun visors for the car that fold up in a small circle. Love it!

Really functional add on for rear facing convertible car seat! Baby is no longer blinded by the sun as he sits near the window. I didn't find it worked very well on the stroller but I like it a lot for car seat.

Fits well on the pockit stroller and dramatically increases shade coverage. The upper straps can't be adjusted, but luckily they still effectively secure the shade. Folding the stroller without completely detaching the shade takes practice. I was able to undo the upper straps, fold the stroller, and tuck the Manito shade under the pockit's shade.

This sun shade is AWESOME! I have three different strollers, and none of them have a long enough shade on them to block the sun out of my son's eyes. It was driving me insane until a lady recommended I buy this off of Amazon. This fits on all three strollers!!! I heard you can attach it to a car seat, but a car seat tech told me it wasn't safe. Now I don't have to worry about the sun going in my baby's eyes when going for a walk/jog! It's easy to fold up and comes in a mesh bag that you store it in when not in use. I actually just placed another order for a second one so I can leave one at my moms house when she is babysitting for me. Great product and I highly recommend it.
