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.

Very nice suit, but too small

It's a very nice suit - but too small. Will purchase again in a larger size.

Good quality and cannot beat the value you get with a suit
Size: Medium, Color: Black
I recently purchased the WEEN CHARM Men's Suits Slim Fit for my son's homecoming and I must say, I am impressed with the quality and fit of this suit. Firstly, the material used in this suit is of exceptional quality. The fabric feels soft and smooth, and it has a nice weight to it which gives it a luxurious feel. The suit doesn't feel cheap or flimsy at all. The slim fit design is impeccable. It hugs my son's body in all the right places, giving him a sharp and stylish look. The suit is tailored to perfection and accentuates his physique beautifully. I also appreciate the attention to detail in the craftsmanship. The stitching is neat and sturdy, and there were no loose threads or flaws that I could find. The suit looks like it was made with care and precision. Additionally, the suit was surprisingly comfortable. My son didn't complain about any discomfort or restriction of movement throughout the evening, which is always a plus. The only reason I haven't given it a five-star rating is because the suit did require some minor alterations for a perfect fit. Nonetheless, this is a small inconvenience considering the overall satisfaction we had with this purchase. In conclusion, I highly recommend the WEEN CHARM Men's Suits Slim Fit. It is a stylish, well-made suit that will definitely make a statement at any formal event. My son looked dashing in it and received many compliments.

Fit like a glove and soft to the touch.
Size: Small, Color: Black
My son loved the suit. It was not itchy. The fabric was soft. He did not like the vest but it is because he normally wears baggy clothes. He did not want a slim fit suit but he ended feeling good in it. For the price you can't miss. He is 140 lbs and is 5'7". We used the sizing chart for reference and bought size small. The length and waist of the pants were perfect and the arms were just right.

Awesome value! Great fit!
Size: XX-Large, Color: Black
Complete men's suit for under $70!!! Crazy!! My husband is thrilled with this suit! We ordered a XXXL but it was a bit baggy. Ordered the double XL and it was perfect! Husband is 6'1, waist 38, broad chested. No adjustments or hemming needed! Love it!
