The One4Life® Slim all-in-one car seat takes your child from birth to big kid with trusted Britax safety, ClickTight® installation, and a slim SpaceSaver™ design. As a convertible and harness-2-booster seat in one, it grows with your child for 10 years. It starts rear-facing with an extended capacity of up to 50 lbs., so your child can ride rear-facing longer. It easily converts to forward-facing toddler mode (up to 65 lbs.) and high-back belt-positioning booster mode (up to 120 lbs.) when your child is ready. With a slim outside and spacious inside, the 17.5” seat is designed to fit 3 across* without compromising safety and comfort. ClickTight helps you install with confidence, every time. The base and shell are easy to wipe down for hassle-free cleanup. The car seat cover is safe to machine wash and dry, and it’s naturally flame-retardant with no added FR chemicals. 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.

Works great, could use a better sprayer
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
I gave it 4 stars ONLY because I've had the nozzle break on at least 1 of these. So they could improve the way it sprays, but overall I'm very happy with the product. It keeps my whole family from getting burned and goes on clear. I love this because my kids always complain that they don't like the whitecast, so this one is a keeper!

Really nice sunscreen
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
I always buy kids sunscreen because everything else burns my eyes. I haven't notices this stuff burning. It smells really nice and doesn't feel yucky going on like some stuff does.

DOESNT SPRAY do not buy
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
Doesn’t work AT ALL. And I’m annoyed because it’s not eligible for return even with prime. What am I supposed to do with a sunscreen that won’t spray? YES, it’s in thru blocked position, it will not spray. I’d love my money back please.
