This sweet onesie is a great basic that can be integrated anywhere into baby's wardrobe. Made of 95% Bamboo and 5% Lycra, our Bamboo basic pull on pants are incredibly soft and luxurious. Bamboo is an eco-friendly, sustainable crop that grows wild without the aid of fertilizers or pesticides. Bamboo fabric is naturally antibacterial, antifungal and antistatic and absorbs water 3 to 4 times better than cotton. This keeps your baby's skin cool and comfortable, rather than sticky, in warmer weather.
