This overall is specially designed for active children who like to play outdoors. All seams are taped and waterproof and the material is dirt and water repellent. The main material is elastic, the knees are reinforced with durable material and the buttocks are insulated - all this makes it fun to crawl on the ground. The detachable and secure hood protects against wind and comes off easily if it should get caught in something. In the overall, the child is ready to explore nature!
