Finally something that actually replaces blankets for my restless sleeper. We put a thin PJ layer under this 2.5 TOG and our nights went from wrestling matches to peaceful — no more waking up to uncover and recover.

We've been using this as a standalone sleep sack replacement and my daughter sleeps straight through now. The 2.5 TOG is perfect for our house at night, and the leg openings mean she can actually walk to the bathroom without me unzipping the whole thing.

My toddler runs warm but kicks off blankets all night, so this onesie solved our sleep problem completely. Wearing it on its own is enough for our 68-degree room, and the legs make middle-of-the-night diaper changes way easier than a sack.
