[0] Warmth [Moby Wrap] Can get very warm, since you will have 3 layers of the thicker jersey-knit cotton wrapping around you and baby. [Wrapsody Stretch Hybrid] 
Lightweight (feels like a thin, cotton t-shirt) and wraps without much bulk. Can be used in carries with fewer layers to be a bit cooler for you and baby.
