Baby Muslin Sleep Bag 0.5 TOG in Tanboocel® Bamboo Viscose - Tiny Engineers

The lightest sleep bag we make, rated for warm nurseries between 24 and 27°C: summer nights, top-floor bedrooms, and the many homes that were never built with central air. When a 1.0 TOG bag starts to feel like too much, this is the one to reach for instead.

Tanboocel® is a branded bamboo viscose made through a closed-loop process that's third-party verified, with a lower water and chemical footprint than the generic bamboo rayon many brands quietly label "bamboo." It gets noticeably softer after the fifth wash than it is on day one, the opposite of how cotton tends to age over time, and it takes the dryer better too, with less pilling and shrinkage over repeated cycles.
