Remember taking a favourite toy on your adventures? The Advansafix PRO will be your little one's faithful friend too - always there when they need it. Giving you peace of mind for years, Advansafix PRO is designed to grow with your little one. Approved to the latest i-Size safety standards (UN R129), it gives your child ultimate protection on every journey. Converts from a harnessed seat to a highback booster seat in easy steps. With the SICT, XP-Pad and SecureGuard*, your child is optimally protected in both side and frontal impacts. Every detail has been developed in Germany and designed to give you confidence every time you buckle up your child.

Ultimate safety
Give your child maximum protection on every journey. The 5-point safety harness can be used until your little one reaches 105cm (maximum 22kg), meaning you can rely on the Advansafix PRO to keep him/her safe for longer. This seat is equipped with advanced safety features - rest easy, the SICT, XP-PAD and SecureGuard work together to provide the best possible protection during an accident.

Head to hip protection
Providing your child with the best protection as they grow. The highback seat shell gives head to hip support for your little one, while belt guides ensure correct positioning of your vehicle`s 3-point seat belt. The padded headrest brings safety and comfort to your child’s head and neck, so rest assured he/she is protected on every journey.

Neck and chest protection
No matter how carefully you drive, you need to safeguard your child from other road users. Protect your little one's precious neck during a frontal impact with the shock-absorbing foam XP-PAD. In an accident it reduces abrupt forward head movement by up to 30%*, preventing your child's chin from hitting their chest. The XP-PAD adds a comfortable padded edge so the seat belt does not cut into delicate skin.

Advanced side impact protection – SICT
Protection for your little one during a side collision - Side Impact Cushion Technology (SICT) reduces the force of an impact by up to 40%* and directs the forces away from your treasure. Simply adapt the SICT on the side of the car seat closest to the door and you know you're giving your child the very safest ride.

Extra safe 5-point harness
Protect your child from serious injury by choosing this car seat with a 5-point harness. In the event of a collision, the harness distributes the force of the impact across five points to the seat's protective shell. Your child's movements are reduced during a collision thanks to the soft performance chest pads. The pads bring even more comfort to the secure 5-point harness and, for those inevitable messy moments, they can be removed for washing without having to detach the straps.

Comfort and flexibility as they grow
Give your little one a comfortable ride - even when they are not so little anymore! Just like a faithful cuddly companion, the Advansafix PRO brings maximum comfort for every stage of childhood - from toddler to tween. No hassle for parents - the spacious, softly padded seat and headrest adjust effortlessly so you can create the perfect fit. Switching from the 5-point harness to your car's seat belt means there is no need to buy another car seat - Advansafix PRO protects your child from 15 months to 12 years. Busy day of adventures? Recline the seat at any age so even your bigger kid can nap in an extra-comfortable sleeping position.

Peace of mind for parents
Relax: there's no need to buy a new car seat as your toddler gets bigger. The lightweight Advansafix PRO grows and protects throughout their childhood, making it a faithful companion on every journey. Effortlessly adjust the headrest and harness simultaneously, so you're always ready to get out and about - even if your darling's had another growth-spurt. When your child is big enough, switch from the 5-point harness to the 3-point vehicle seat belt with the Flip&Grow function.

Removable washable cover
Things can get messy in the car – drinks spill and children can get travel sick. That is why Britax designed a machine washable seat cover that's easy to remove, so you can clean up quickly and get back to enjoying your adventures together.

Full Coverage
Size: Large, Color: B2207sp
They're nice and light, super stretchy, and not too tight around the edges. Im a size 14 and got a large amd They're a smidge tight, but I think if I would get an xl theyd fit perfectly, They're still comfy as is. One stipulation I had is I wanted them to cover my whole butt cheeks, nothing cutsie short cut, not for this. They cover my entire booty cheeks and stay there pretty well. Oh and also no camel toe! Id buy them again and would recommend them to anyone.

Make sure you size up!!
Size: 4X-Large, Color: B004
Allllllmost 5 stars if the sizing was correct. I’ve been on the hunt for a decent fitting pair of women’s boxer briefs. I would say these are more so boyshorts. That being said, I wanted something loose for sleeping in so I got TWO sizes up. I normally go for a 2x and got a 4x and they’re perfect fitting. So, you didn’t get what I was looking for but did end up with some decent fitting undies. So I can’t complain too much. Just not the boxer briefs I was hoping for. Super stretchy and soft. Comfortable for sleeping in.

Really comfortable, good fit
Size: 6X-Large, Color: 5 Pack(black,black,blue,blue,light Coffee)
These are very lightweight and comfortable. The material stretches freely and doesn't bind up anywhere. If you go by the size guide, they should fit perfectly neither too loose nor too tight. Would definitely recommend.

These don't work for me...
Size: Medium, Color: B005
First the good... I like the material; it's very soft, light, and stretchy. I also like the colors, but that's all I like about these boyshort panties. My main goal for panties is to have them NOT ride up into my butt crack leaving the bottoms of my butt hanging out. It's probably comfortable for some, but it drives me nuts to feel this constant need to pull them out of my butt crack and down over my butt cheeks. If I wanted my butt hanging out I'd buy thongs, LOL. The part I really don't understand, is why they make the front and the back the same width/length. I mean clearly more material would be needed in the back to fit around two round humps, right? I mean I guess unless you have what I call a pancake butt, I don't see why there shouldn't be more material on the backside of the underwear. Why is it so dang difficult to find underwear in this style to fit up over butt cheeks? If I pull them down enough to cover the bottoms of my cheeks then the waistband is sitting right at the top of my crack which is extremely annoying (then I feel this constant need to pull them up!) especially when the front is long enough to go up to my belly button!! Who are they making these underwear for??? Ladies with FLAT butts apparently. For reference, I'm 5'5" 130 lbs, hips 37", waist 27", athletic build, as in lean but with muscular glutes & quads from speed skating. Not only are they not made big enough to go up over my rump while still keeping my cheek bottoms from hanging out, but they're too long in the front cause they constantly roll up in the front. I've even tried turning them around, even though they seem to be exactly the same front to back, and they fit exactly the same, no surprise there. I may just be out of luck finding comfy boyshort panties that actually fit the way I want them to. :/
