One4Life takes your child from birth to big kid with Britax Safety and ClickTight Installation. It easily converts from a rear-facing infant car seat, to a forward-facing 5-point harness, to a high-back belt-positioning booster seat. SafeWash cover is safe to machine wash and dry.

ClickTight is as easy as buckling a seat belt, so you can install with confidence, every time. Color-coded belt paths show you where to route the seat belt for each installation mode. Plus, easy-read indicators help you find the correct recline angle.

A high strength steel frame, crumple zone, and V-shaped tether help absorb crash energy. And, 2 layers of side impact protection surround your child’s head, neck and torso.

As your baby grows, adjust the 15-position headrest & harness in seconds to create the perfect fit. When it’s time for booster mode, simply tuck the harness into the built-in storage compartment. With cooling channels, premium padding and built-in arm rests, your child will love the ride.

Fabrics Great, Size a little Big, Overall Pretty Good
Size: Medium, Color: Dark Navy
This suit was truly great, the size for the pants and the vest were pretty on point, maybe a little long for the pants. The jacket was way too big though compared to the rest. Overall pretty good suit for the price, very surprised at the build quality and faabrics.

Better than expected!
After reading the reviews about it being oversized, I was able to get the right fit that I wanted. It is on the thinner end as far as sweatshirts go, but I tend to run hot so I was quite pleased that I got a long sleeve shirt that didn’t make me sweat. Now, let me tell you about the quality …. For some reason I thought the design was just printed on it, but it’s not! The “jolly” is sewn on, and the stripes don’t look cheaper. I love the red banding at the neck, sleeves and waist. It’s so comfortable, and I got compliments on it all night. I would definitely buy it, or any of their own sweatshirts, again!

Runs big. Fabric is nice. Love the color
It's a nice color of green and feels great. I ordered a medium due to the reviews. It's a larger than a normal medium so it's slightly too small. I usually wear XL and sometimes L. So, it does run big. I returned it but probably will order a L.
