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.

Nice.
Size: Medium, Color: Prime Pink/White Assorted
These were great quality and perfect fit. They held up. Under Armour seems to make the better quality socks than others.

Perfect Fit and Versatile for All-Day Wear
Size: Small, Color: White/Cerise Assorted
I absolutely love these socks! Though they're technically kid-sized, they fit my size 5-6 women's feet perfectly and are incredibly versatile. I wear them for workouts, casual outfits, and pretty much all the time. They’re reliable, well-fitting, and comfortable throughout the day. The quality is excellent, and they hold up well even with frequent use. If you’re looking for socks that combine great fit with durability and style, these are definitely a top pick!

Great socks
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
Love these little socks. Soft and stay in place, no falling down in my shoe. I will definitely be buying more. Holding up well after multiple washings.

Great fit, no slip
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
These looked too small for my feet, but now I love wearing them as they are comfortable and stay on my feet! They look great and the colors are easy to match. Excellent value for the money in my humble opinion.
