Temperature Regulation: 37 Degrees
If you’re too hot or too cold, you can easily get up and fix the problem. Not so with a baby. They let you know by screaming their little lungs out. 37 Degrees’ temperature regulation bodysuits employ the same technology NASA uses to keep astronauts comfortable in space (they store heat in the fibers, and release it when needed). Hey, if it’s good enough for cosmonauts, it’s good enough for your little explorer.

Pricing: around $50
Sizing: 0-18 months
