Machine washable, non-toxic water-based dyes, and designed to soften with every wash for long-lasting wear. Choose the Right TOG for Safe Sleep: Temperature-matched for year-round comfort with 4 TOG ratings (warmth levels): 0.2 TOG (71 °F +/ 22 °C +), 1.0 TOG (67–75 °F / 20–24 °C), 2.5 TOG (59–69 °F / 16–21 °C), and 3.5 TOG (53–65 °F / 13–19 °C). Eliminates loose blankets while maintaining the ideal temperature for safe sleep. Refer to our What to Wear guide for safe dressing options. Freedom to Move, Easy to Layer: Bolero-style jacket shape fits comfortably over sleepwear without restricting movement. Keeps arms cozy without adding bulk or overheating. Ideal for Transitional Seasons: Use on its own as a light layer or pair with heavier TOG sleepwear as temperatures drop-simplifying layering without needing a full outfit change.
