The Pragmatic Pick: PurComfy Supersoft Pragmatic Pick

PurComfy Supersoft is our overall Pragmatic Recommendation for sleep sacks and swaddles, and it takes this head-to-head too. The key advantages — 1.0 tog works for most room temperatures (68–72°f) and bamboo viscose is incredibly soft against baby’s skin — give it an edge that’s hard to beat in daily use. Gunamuna has genuine strengths (notably patented diaper zipper opens from the bottom — no full unzipping), but for most families, PurComfy Supersoft offers the better overall package of performance and everyday convenience.
