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.

Recommendation – Britax strongly recommends:

Children ride rear-facing to the highest weight or height specified

Children should remain in a child seat with a 5-point harness until reaching the maximum weight or height allowed

The top tether be used at ALL times when installing the child restraint forward-facing.

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

My favorite underwear
Size: Medium, Color: Multicoloured C (5-pack)
Super comfortable!! They are soft and breathable. No pinching, no shifting, and relatively invisible in skirts, pants, and loose dresses. True to size. Excellent quality, holds up well. Only thing is that the wording on the front does come off after a few washes, so you have to differentiate the front from the back of the underwear by how high the seam comes up. I almost exclusively wear this underwear now, I love it!

Incredible Comfort
Size: Large, Color: Multicoloured F (5-pack)
Amazing; I’ll be ordering more. Super soft, lightweight, smooth under clothes, incredible comfort! Best underwear! I ordered these because I’m tired of underwear lines when wearing biker shorts/leggings. Other boy shorts were too long or the bottom hem too thick and both of those issues left lines around my upper leg. THESE are *just right* - perfect length and fit. No panty lines on close fitting pants, comfortable under other pants and dresses, great with jumpsuits, and fit well under slip shorts with dresses. NOTE: These take longer to dry, than similar clothes, in the dryer. No shrinking though. SIZE: I ordered these in size L and they fit perfectly. A little snug when first on but they loosened up. For reference I’m 5’4” tall, about 175#, carry my weight in my hips and backside,wear size L sweats/pajamas/loose pants, size 12 jeans.

Full coverage and full comfort
Size: XX-Large, Color: Multicoloured C (5-pack)
These boyshort underwear are a dream. They’re very soft, very stretchy, and very comfortable. They do not shrink when they’re washed. They’re heavy enough to make you feel like you have something covering you for discretion, but light enough to wear under any type of fabric. I have wide hips and I’m older so I don’t have a tight perky butt anymore. Most underwear tend to either ride up on me or become very uncomfortable. These stay where you put them. And they come all the way up to your waist so that there is no panty line whatsoever. The waist line is soft and comfortably. It does not dig in. They do not ride up and drive you crazy they stay where you put them. I would recommend them to anyone young or old. I have tried so many different styles and materials to find underwear that’s actually comfortable. These are the absolute best I have tried in five years. I just threw all the rest of them out.
