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.

Very generous cut & really well made.
Size: Large, Color: White, Size: Large, Color: White
All cotton, 100%. Really well made. Great stitching and excellent weight. Very generous sizing. Lots of online clothing runs small, so I ordered a large and it is much too big across the chest and in armhole size. Should have ordered a medium. Will reorder. But this price was so good that I will not return the large. Will donate them to my local food & clothing pantry. I think they will be great for warm weather, but also for layering in these cold months.

one fits, other too big
Size: X-Large, Color: Navy/Sage Green
The good: made with a nice fabric, a good weight and soft. Color for both shirts is what I expected. I wish I could keep just one shirt. The navy blue tank top fit perfect and was comfortable. Green, same size as the blue one, was uncomfortably big. Arm holes 2 whole inches larger than the blue top. This type of inconsistent sizing is frustrating.

Good quality, not sure on fit
Size: X-Large, Color: Black/Mariner Stripe
I looked at the general comment on this top and it stated frequently returned due to loose fit. My measurements are close to size xl so I figured if they run large/loose then they would fit me fine. My bust is 46 1/2" and I probably should have gone xxl. The tops are snug across my breast and I will have to be adjusting so it does not pull a gap at the side of the arm pit area. However the top is not too snug, also not loose throughout the rest of the body so don't know how I would feel about a size larger. The quality is nice, medium weight cotton. No see through and no falling in creases. I hope washing these in cold and line drying will keep them from shrinking. I will keep these because I do like the quality and length but have not decided if I will order more or not.

Weirdest armhole proportions I've seen
Size: X-Large, Color: Navy/Sage Green, Size: X-Large, Color: Navy/Sage Green
There are a few nice things about these tanks -- I like the colors, there's a little extra length in the back, and the fabric is a thick quality fabric. I appreciate the fact they're 100% cotton and was looking forward to wearing these. Overall, the tanks fit as I would expect for the size. But what in the world is up with the dimensions for the arm holes? There is a significant amount of extra fabric that bunches up and looks awful (see photos) I've never had this happen on a tank top before, even one that's a size up. It's really strange and I'm disappointed that I can't keep these because of it.
