The Britax Allegiance is safe and comfy for your little one while you’re on the go. Britax SafeCell Impact Protection is a system of patented safety features that provide advanced protection. A foam-lined shell provides side impact protection in the event of a crash. Plus, installation is easy using lower anchors that lock into place with a click and are released with the push of a button.
Specifications
- ClickTight Installation System is safe and simple to use. Open the front of the car seat, feed the seatbelt through the indicated path, buckle and click the seat shut.
- 3 layers of side impact protection, formed by a deep energy-absorbing shell, quick-adjust head protection and side cushions, absorb energy and shield your child from the most severe type of collision.
- SafeCell Impact Protection includes a steel frame, energy-absorbing base and patented V-shaped tether.
- Impact-absorbing base compresses to reduce the force of a collision.
- Impact-stabilizing steel frame offers superior strength where you need it most: at the connection point to the vehicle.
- Patented V-shaped tether minimizes seat rotation with a unique two-strap design and staged-release stitches that slow and reduce forward movement during a crash.
- Click & Safe Snug Harness Indicator gives an audible “click” to aid you in the proper tightening of your child’s harness.
- Quick-adjust 14-position harness and 2-position buckle allows you to easily move the harness upward and buckle outward for a comfortable, secure fit as your child grows.
- 7-position recline with automatic level indicator adjusts for proper recline rear-facing or for comfort and the best vehicle fit forward-facing.
- Plush foam padding and fabrics for premium comfort.
- Easy-buckle system keeps buckles and straps out of your way when positioning your child.
- Easy-remove cover for cleaning without having to uninstall the car seat or remove the harness.
- Suitable for children 5-65 lbs.
- 1-Year Limited Warranty.

I recommend them
Color: Black/Deep Blue/Red/Deep Grey, Size: Small
I bought it for my 11-year-old son who is 5'4" tall and weighs 124 pounds, and they fit him perfectly. It doesn't roll up and it has good elasticity

Finally boy shorts done right
Color: (6 Pack) Brown and Pink, Size: 5X-Large
So am going to be one of those, cause I do wished I had one of these reviews to fall on. First off, I am extremely picky about my panties. I am a large person. So comfort is a necessity. I have to have stretch, but also they have to be tight enough to not move or show things. I like longer legs, stretch, and seamless silky soft material. After YEARS of hunting, I did find some perfect ones from a big brand (Aerie) which are wildly overpriced at $23 per PAIR! Found these and they are perfect. Only difference is these have the thin waistband and the Aerie has the wide yoga waistband. I love these so much I bought 6 packs because I know how hard it’s to find the perfect boy shorts for larger women. Smooth, comfortable, seamless, long, and affordable! I did have to size up 2 sizes. In the other brand a xxxl is perfect.. I got a 5x in these. Probably could have went with the 4x but the 5x gives comfort. Im so glad I did find these.

The underwear of all underwear!
Color: (3 Pack) Leopard Print, Size: X-Large
These have quickly become my favorite underwear and even my go-to shorts for lounging around the house. They’re incredibly comfortable and don’t dig in or roll down like so many others I’ve tried. The fit stays in place, and the fabric has a smooth, silky feel that’s really nice against the skin. They’re comfortable enough to wear all day and have held up well so far. I’d definitely recommend them if you’re looking for something soft, comfortable, and easy to wear
