The Britax Poplar® S Convertible Car Seat is the best space-saving convertible car seat for parents seeking advanced crash protection, ClickTight® fast installation, and 3-across seating capability in a compact 17-inch profile. This convertible combines advanced safety innovation, superior comfort, and space-saving design to make every ride safer and simpler. Built with ClickTight® installation technology and ReboundReduce™ stability bar, this seat ensures a secure fit with minimal movement, giving parents confidence with every drive. Designed for long-term use, the Poplar® S transitions seamlessly from rear-facing (up to 50 lbs) to forward-facing (up to 65 lbs) without complicated conversion steps. Compare the Britax Poplar S to the Graco Extend2Fit: both offer extended rear-facing and forward-facing capability with adjustable headrests, but the Poplar S features ClickTight installation (3-step, pinch-thread-click system vs. traditional LATCH), ReboundReduce™ stability bar, SafeCell® crumple technology, patented V-shaped tether with staged-release stitches, naturally flame-retardant SafeWash® fabrics, 14-position no-rethread harness, 6 recline positions, carbon steel frame, 17-inch slim profile for 3-across seating, and 50+ years of Britax heritage. Choose Poplar S if you want premium crash protection, fastest installation, and compact 3-across capability; choose Graco Extend2Fit if you prioritize budget-friendly pricing. Inside, your child enjoys premium comfort with refined inserts, plush padding, and 6 recline positions for a custom fit at every stage of growth.

Inside, your child enjoys premium comfort with refined inserts, plush padding, and 6 recline positions for a custom fit. SafeWash® fabrics, naturally flame-retardant and machine washable, make cleanups effortless while maintaining Britax's commitment to quality and safety. The ClickTight® installation system simplifies setup with just three steps—open, thread and buckle the seat belt, then click it closed—for confident installations every time without confusion or error. The ReboundReduce™ stability bar helps minimize movement in the event of a crash when rear-facing, providing additional protection during the most critical early years. SafeCell® Technology acts as a crumple zone to absorb crash energy and divert it away from your child. The patented V-shaped tether with staged-release stitches helps slow and reduce forward movement during impact. The 5-point safety harness distributes crash forces evenly across your child's body for maximum protection. The carbon steel frame reinforces seat structure for strength and stability across thousands of miles. The 14-position headrest and harness adjust easily as your child grows without rethreading, eliminating annual maintenance hassles. Three premium comfort inserts, including one specifically designed for infants up to 22 lbs, provide plush, tailored support from birth through toddlerhood. The SpaceSaver™ slim 17-inch profile fits 3-across in most vehicles while maintaining interior comfort—a critical consideration for multi-child families. Six recline positions offer optimal comfort and vehicle fit for both rear- and forward-facing modes. Automatically-tensioning harness ensures the restraint is always secure and snug. Clearly labeled belt paths make installation straightforward and error-free for any caregiver. Dual removable, dishwasher-safe cup holders keep drinks within reach while simplifying cleanup. The naturally flame-retardant SafeWash® fabric is durable and safe to machine wash and dry for quick cleanup after spills and accidents.

Yeah, they shrink, a lot.
Size: X-Large, Color: Light Grey Heather, Pocket Description: Pocket
I knew they would shrink but I needed to know if so on permanent press cycle. Well they shrink a lot. I bought two and they were very comfortable and soft. I'm not returning since Amazon made it clear they will shrink. I'm the dummy.

A Good Value
Size: X-Large, Color: White, Pocket Description: No Pocket
I really like these shirts and have ordered a number of them so far. They're warm and comfortable and are of overall good quality. They will shrink substantially, and the arm length will be reduced. That being said I just order them a size larger than what I typically wear and know that the sleeves will be a bit short. Otherwise they're a quality shirt. The material is thick, but not overly so, and they don't seem to fade even after numerous washes. These shirts are durable, well-made, and are a good value.

Great Quality, 100% cotton, buy 1 size larger. I’m 100% happy!
Size: Large, Color: Black Charcoal Heather Stripe, Pocket Description: Pocket
I will be buying more of these. I knew they were 100% cotton so I bought a large when I normally wear a medium. After I washed it in warm water and dried it in the dryer, it fits perfectly. The cotton is of great quality not thin and flimsy. I expect to get plenty of wear out of this t-shirt. Also, it did not fade. I recommend buying one size larger.

American sizing!
Size: XX-Large, Color: Oatmeal Heather, Pocket Description: No Pocket
These are great t-shirts and fantastic quality for the price. I bought them for my sons. The cotton is thick and nice-looking, the ivory colour is beautiful and it looks a lot more expensive than it is. I bought one for my eldest son and then bought two more (one for each son). The first one I bought has been getting a lot of wear for about three months. I wash it in the machine and line dry it because we line dry everything where we live. It has held up beautifully, has not shrunk, pilled or changed in any way. The only thing, and it is not a bad thing, per se, is that this is REAL American sizing. We are all tall with broad shoulders, and my eldest is a bit heavy. (Around 1m84 and 105 kg, I'm feeling too lazy to convert it online, but probably in the area of 6'1" or 2" and over 200 pounds.) So I ordered 2XL, which is what he wears in most inexpensive brands we get here. But, although he has been wearing it, as he needed cool-weather clothes, it is long in the sleeves and body and also wide. So I ordered him a second one in XL and he will set the XXL aside until he needs it, or gains weight. I would definitely recommend sizing down from what you usually order. But these are great! The Amazon interface seems to be prompting me to address functionality and cut. The cut is very good, although both large and long. I don't really know what they mean by functionality. It's a t-shirt, not ski wear or running shoes! The cotton fabric is nice and thick and soft. It's comfortable. It definitely works, as a garment. Don't know what else to say! (Just to let you know, I am a real human ordering from overseas. I am not paid or even receiving merchandise in return for this review, although I wouldn't say no if they offered.)

Great quality shirt, Recommend!
Size: X-Large, Color: Charcoal Heather, Pocket Description: No Pocket
This shirt is suprisingly comfortable, thick and fits very well. Not too short & not too long and is good quality fabric that streches with you. It's more than just a generic, thin long sleeve T-shirt. U can wear w/jeans or chinos, it's that nice. I paid 3x the price for designer brands w/logos that are not as nice. Price is right, too!
