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.

This is a fantastic jacket for the price. I was very impressed by its appearance. I wore the jacket in Las Vegas and got so many compliments from both men and women. Pair this with a black turtleneck and you will be a superstar.

it caused a fight
Color: Gold, Size: X-Large
I completely mis-read the room.... I got this jacket as a White Elephant gag gift for our Christmas party. I thought it would be funny to see some 50-60 year old conservative dude open this up. There is nothing subtle about this jacket. It's bright. It's flashy. It's bold. The guys fought over it. It was the most stolen gift of the night. When the first guy opened it, the whole party stopped for a minute while he proudly tried it on and everyone took pictures. And each time it was stolen, the same thing happened. The loser moped. The winner boasted. It was not at all the reaction I expected from this group - it was awesome! And to top it off, a couple months later another guy in the group "borrowed" the jacket and wore it for his wedding. His wife - also part of our group - absolutely loved it! He has no plans to return the jacket to any of the previous owners. Don't be surprised if you see a sparkling flash of light in the stands at a Vanderbilt basketball game! Their colors are black/gold, so he's going to make full use of the blazer! Aside from making a great story for all of us, this jacket is very well made. The sequins are firmly attached. The sleeves are the right length, etc. It's comfortable to wear and the sizing feels accurate. I was expecting a "costume" piece, but actually got a quality blazer.
