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. *Britax cannot guarantee 3-across fitment in all vehicles.

Perfect and not bulky
Color: Apricot, Size: 17.3 Inch
Love this slim backpack, plenty of room for my laptop and so much more. Lots of zipper and mesh pockets. I like the separate compartments for the laptop. It’s well designed and very functional. I wanted something that was not bulky and this fit the bill, it’s really great. The material is nice and easy to keep clean. Seems well made, I’ll update down the road if that changes. I recommend this backpack.

Perfect work travel bag!
Color: Black, Size: 14 Inch
Perfect work bag! I was looking for something for a petite frame. Can fit a lot in it, worth the money, love all of the pockets. Can carry two ways - either with handles or wear on back like a backpack

Perfect backpack to use as a purse
Color: Champagne Brown, Size: 14 Inch, Color: Champagne Brown, Size: 14 Inch
I LOVE THIS BACKPACK! It's perfect as an EDC backpack used in lieu as a purse. It's small enough to use daily and to keep basic necessities in. It has a main compartment, a basic compartment for a laptop or iPad, and a small front pocket. There is a small area that closes with a snap where the handle comes out of that can be used for storage as well. I like to keep my sunglasses or vape in it. I like to wear a backpack when shopping, it makes it easier to have my hands and arms free and I also don't have to worry about my purse in a cart and someone dipping into it when I'm not looking. While I like to wear a backpack, I don't need an ACTUAL backpack used to carry large objects and this fits the bill. I'm able to fit my wallet, phone, 10" iPad, journal, tech kit, small makeup bag, keys, glasses, gum, coin purse, misc. pouch in it and it still has room at the top. The quality is excellent, as all Golf Bags are. The color is a beautiful neutral medium taupe (I got the light brown/cappuccino? color) but I would love this bag in black, blue, and beige! The blue color is such a pretty blue!

Good for office and school.
Color: Black, Size: 16 Inch, Color: Black, Size: 16 Inch
Looks good and it's lightweight. Soft material for the design. Storage is ok, could be better with softer cushions and a strong cover material. Zipper is sturdy so far. Versatile. Cons: Has no strap to keep laptop in place. Laptop cushion not thick enough.

LOVE IT! But let's clarify the color!
Color: Apricot, Size: 14 Inch
Hi! I bought the 14" backpack in apricot. A few things stand out to me: 1) High Quality-this is a quality-made product. 2) The Apricot color is closer to a light tan or light sand color. 3) It was not as wrinkled upon arrival as I read elsewhere. I do not intend to steam the wrinkles out. I don't see that as necessary and I hate wrinkles. It's beautiful! It's high-quality. It has every pocket and function you'd want. (see the videos.) Once I use it more, I'll add to my review if necessary. I love it. I'm happy a bought it and I think you would be too! Nice to get a product with such obvious quality!
