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.

29 years of riding a Harley, THIS is the best sun protection I have found for long SUNNY day rides!
Size: 6 Ounce (Pack of 2), Style: SPF 50, Size: 6 Ounce (Pack of 2), Style: SPF 50
This is my "Go To" Sunscreen of choice that I find is the best to quickly spray my arms down good before a long Harley Motorcycle ride! I have tried many brands and styles from creams to face specific to lip balm but this one can does it all in my case! I quickly spray my arms ( no rubbing in required ) and a quick spray in my hand and I then rub my nose and ears , face and i'm ready to ride and I am protected! Most times I only apply this product once a day and works better than anything else for my needs. I am light skin but I have ridden lots this Summer and my arms never burn and now have a deep tan as we are entering fall... I made the mistake of trying a store brand that looked like this product but was oily and never used it but once! This Banana boat once sprayed on my arms, I never think about it again as its gone but still protecting my skin! This is the best I have found after 29 years or riding a motorcycle to protect my skin with the least amount of trouble , No strange or tropical smell, NO greasy feel just quick applied lasting sun protection that has proven itself mile after mile! The BEST Sun product I have found!

It is quick to apply and I've never gotten a burn with it. It doesn't leave marks on my clothing.

I've used this product for years. I spray it into my hands to apply so it doesn't go out into the air. I have never gotten a burn with it and it is. so easy to apply. I don't have to worry about white marks in my clothes. It doesn't take long to apply.

Affordable and Effective
Size: 6 Ounce (Pack of 2), Style: SPF 50
It’s really good for the price and super easy to apply. I would recommend having someone help with your back or harder-to-reach areas, because any spots you miss will definitely show if you’re out in the sun for a while. I’ve used this for a couple of years now, and it’s one I keep going back to. If you have more sensitive skin, there may be better options out there, but I personally haven’t had any issues with it so far.

Us it Every Day
Size: 6 Ounce (Pack of 2), Style: SPF 50
This is really a great product and easy to use as a spray. I bike ride every day and my ears/face are exposed to the Florida sun. I use it primarily on my face every day. A moment after a quick spray, the product dries, is not sticky, etc. This will become a recurring purchase.

Good protection from the sun.
Size: 6 Ounce (Pack of 2), Style: SPF 50
Does a good job keeping sunburns away. Spray sunscreen never lasts as long as rub-in sunscreen (ie, the bottles run out quicker) so it seems pricier to cover the whole family, but we keep this on hand for days we'll be outside!
