Purchased new around 2023 and used almost daily from newborn to 6 months (alternating with several other swaddles). Made of 100% cotton, with a thin TOG of 1.0, perfect for spring and summer temperatures! From the overseas brand (Verbaudet), the size is 68cm, equivalent to 6 months. There is a small scratch in one place (see photo 3), but there is no noticeable yellowing, and it does not affect daily use. Thank you. #Swaddle #SleepingBag #ThinSwaddle #TOG1.0 #Sleeper
