Ready to go with room to grow! The Poplar™ S convertible car seat takes the stress out of moving to the next car seat stage thanks to the patented ClickTight® installation and slim SpaceSaver™ design. This convertible car seat accommodates up to 50 lbs when installed rear-facing and easily switches to a forward-facing car seat as your child grows. ClickTight technology provides fully open seat belt paths that are clearly labeled and easy to access, and the automatic tensioner takes care of the tightening.

This car seat lets you easily adjust the 14-position no-rethread harness and headrest to help create the perfect fit. The removable infant insert helps to properly position infants 22 lbs and under.

The car seat cover fabrics are naturally flame-retardant with no added FR chemicals, and they’re safe to machine wash and dry time and again. *Britax cannot guarantee 3-across installation fitment in all vehicles

Comfortable to Wear and Easy to Use Every Day
The texture was the first thing I felt. First application feels rather rich but unexpectedly distributes easily throughout the skin. I was worried it would feel heavy, but it blended in more readily than I thought and didn’t leave my skin feeling too oily afterwards. I love that you can use it on the body and face too. One product for the entire family is easier and saves room when packing for trips or holidays. I have used it on myself and my kids when we go out and it has been comfy for all of us to wear. Another thing I appreciate is my skin feels hydrated after using it. Love things that make my mornings easier on hectic mornings. The mixture is smooth and pleasant to wear all day long and does not feel sticky. The container is functional and simple to throw in a beach bag or handbag. I have brought it to soccer games, trips to the playground, family picnics and it has been no problem.

Less cast and the zinc scent is mild.
I use sunscreen regularly. One of the aspects I do not like is the white cast I get from zinc-based SPFs. This one is zinc-based but it has tallow and PDRN. I want to see if they make any difference when it comes application and feel. MY EXPERIENCE WITH THE PRODUCT 1. I received Mystic Orchard’s beef tallow sunscreen with PDRN. Comparing its value, I think the volume is pretty good. I received 2.8 ounces. 2. When it comes to scent, I smell the metallic scent but it is not as bad as the one I have been using for swimming. It is there, but pretty faint. 3. You can tell by the sheen that it is zinc-based. It has the same consistency. 4. What I noticed though is that the white cast is not too bad. It blends fast with the tallow. 5. I like tallows because they contain fat-soluble vitamins like vitamin E for some antioxidants. 6. The cica is nice too for those who need a calming ingredient with their sunscreen. 7. I think this would be good for when going out. I do not think I will be using it for swimming since it is mild in scent and cast. Better to use it elsewhere than just for swimming. OVERALL IMPRESSION: I think that this SPF sunscreen with tallow and PDRN is cost-effective and worth its value if you want a zinc-based sunscreen with less cast and milder scent.

Moisturizing Sunscreen
Size: 2.82 Fl Oz (Pack of 1)
The grass-fed tallow base makes it deeply moisturizing—it feels like a nourishing balm. The PDRN complex is a nice bonus for repair.
