One4Life Slim features a high-strength steel frame, a SafeCell® crumple zone, and a V-shaped tether. As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand. With cooling channels, premium padding, three infant inserts, and built-in armrests, your child will love every ride.

Great product, not the best packaging
Size: 5 Fl Oz (Pack of 1)
Glad I got this. Just returned from a two-week dive trip in the Caribbean. Lots of sun of course! I applied this product on my face and neck prior to first and 2nd dives - I never burned. I'm fair skinned but not a magnet for sun burns. I did not have a prior base that I can speak of. The product works well, and blends into your skin fairly quickly, avoiding the white out from other mineral products. Downside - the container has some type of flow restriction. This had the effect of periodically not letting product out and then spurting out all of a sudden. Not sure if a dud, but except for that I would say absolutely I'd buy again.

Very happy with
Set name: Face - 1.7 oz.
I really like this. Quickly clear after applying. No sensitivity issues. Moisturizing. It does leave a sheen which I personally like and doesn’t feel overly greasy to me.

Set name: Face - 1.7 oz.
This sunscreen has worked well for me and I like that it is a mineral formula. The main thing to know is that it can take a little effort to rub in fully so you do not see it on your skin, but I do not consider that a major problem. That is pretty normal with many mineral sunscreens, and I would rather deal with that than use something that does not agree with my skin. Once applied, I have been happy with it and have no real complaints. Overall, it has been a good face sunscreen for me.

Best sunscreen ever
Set name: Face - 1.7 oz.
I love how light it is, it doesn’t leave a white cast. It even leaves skin looking glowy. It also feels moisturizing. I have sensitive skin that breaks out with sunscreen. It doesn’t breakout with this one! I also love that it’s hsa eligible! Have already recommended and shared with others. I will never switch to another sunscreen.

Works great but very runny
Set name: Face - 1.7 oz.
I’d call this a liquid and not lotion. It literally pours out of the tube without even squeezing so has to be held upright at all times when the cap is off. Makes a real mess (and I do shake it well before opening as the instructions say). Other than the packaging, I really like the product. It blends well with no white cast after rubbing in, is moisturizing without looking greasy at all or causing breakouts, and has provided good sun protection. Impressed! Also like that while water and sweatproof, it washes off with a gentle face cleanser at the end of the day unlike some of the zinc-based products I’ve tried that leave a thick coating and require scrubbing. This is my first Blue Lizard product and I’ll probably keep using it as a daily sunscreen—but definitely not to throw in a bag and take to the beach because of the messy application. Bought the stick version to try out.
