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.

Due to regulatory changes, weight and height ranges may vary by model. Always follow the weight and height specifications listed in your product's user guide and on your product labels.

Tight in shoulders
Its a good shirt, but tight in the shoulders from the get go. Hang dry and don't use a dryer for it. It shrank on low heat. No longer usable. Order a size up from what you are for better fitting.

Well made, great fabric, very tailored look.
Color: Blue, Size: Medium
Really well made shirt! The pattern is perfectly matched all the way around, which you don’t often see. Nice flannel, perfect weight. soft but crisp and manly fabric and buttons are very good quality. Washes really well without fading or wrinkling and the collar stays crisp which is hard to find today! My son loves this so much we bought it in several colors.

Great Fit & Colors!
Color: Black Pink Plaid, Size: Medium
I ordered 3 of these shirts and am very pleased with them. I wear a Medium and the fit was true (5'7" 155 lbs.) The colors are really nice as well, not overly bright and remind of my favorite shirts that are old and faded and feel great to wear. I do worry as to whether or not these shirts will pill easily. I don't believe they will, but only time will tell. I do like these very much and will order a few more in different colors.
