Protective Shell
The enclosed shell design provides enhanced shielding to ensure the child is contained within the protective elements of the child seat. A protective barrier between the child and
the vehicle.

Located in the rear interior and exterior of the seat, the zones offer improved airflow and increased comfort to your child in rearward facing.
Integrated Coloured Belt Paths
Clear, obvious coloured visual belt paths for easier-to-guide correct seat belt installation.

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.

Nicer than I thought they’d be!
Color: White - Set 23, Size: X-Large
Love these!!! I bought a size larger than I usually do and they fit great, so they might run small, dunno for sure. They are comfortable, don’t slide down, and are soft. The spandex is nice, so they are stretchy and wash better than 100% cotton. Oh, and no saggy bottom!

Comfortable cotton briefs
Color: Beige - Set 17, Size: Large
Very pleased with this underwear. Purchased a second pack of four. Fits well, very comfortable and gets softer after washing. Comfortable stretch in the waistband without being too tight. I have had several abdominal surgeries in my life, and my belly will never be flat. I am also elderly and appreciate the fabric being cotton.
