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.

Not polyester! Thank you UA!
I never realized shopping for cotton socks in 2024 would be so difficult. Luckily I found these, and all the other Under Armour cotton socks and they are the best. I cannot wear polyester, and these only have like 1%. I didn't realize our cotton is being replaced by polyester, and I don't like it. Bath towels don't work anymore either... I need my cotton socks and towels, I love incandescent light bulbs, I'll always have a gas powered mower and leaf blower. Also butterfinger should've never their recipe. Just sayin...

Great sock for everyday
Size: Large, Color: Black/Gray (6 Pairs)
So these are awesome but they are slightly thinner than older versions, shorter too. Just FYI if you a long time UA customer. If you have never had their socks, I love them personally and only like one other brand better. They aren’t overly thick and they allow your feet to breath. I never have sweaty feet in these even in my warm boots. I also like that they don’t cut into my feet or get holes in the toes over long terms. The only reason I’ve thrown these out has been fraying near the ankle or someone (kids) thieving them.

My favorite low socks ever
Fit Type: Classic Fit, Color: Gray Assorted, Size: Large
Under armour adult essential Lite no-show socks are 96% polyester and 4% spandex footwear of imported origin. The polyester content of the socks enables them to hold their shape in a better manner along with having a non-absorbent nature. Additionally, it enables the socks to retain the colour in a better manner. Spandex improves their fit along with helping them last for longer time. The flat fit construction of UA Men's Essential Lite is so designed to conform to foot for superior touch and feel. The material wicks engineered within the fabric dry sweat quickly and keep the feet fresh. The embedded arch support further keeps you going by reducing foot fatigue. The set comes with 6 pairs of socks with pull on closure for the perfect fit. Ultrathin lightweight construction of the socks adds to user comfort by allowing users to conduct physical activity and work out while wearing it. Elastic strength of the socks prevents them from slipping down irrespective of the shoes they are worn with. The socks come in 8-12 men shoe size and 9-12 women shoe size. They can be machine washed and are extremely durable while being cost effective. I ordered the socks based on their colour and design symmetry. So far my socks have been through multiple washes and still look new and user ready. I wear them daily because of their amazing fit and plan to buy more as Christmas gifts.
