Engel 70% Organic Merino Wool/30% Silk Onesie in a lively red/orange or blue/kiwi stripe is soft, silky and gently warm. Wool/Silk is a good blend for sensitive skin and provides breathable comfort for the skin. Silk actively balances temperature, giving warmth when it is cold and cools down when warm. Silk can absorb up 40% of its own weight as moisture. Pair with orange/red stripe leggings for a great set. Wash by hand or machine washable on gentle cycle in warm water.
