My two and a half year old son just began wearing these and they are great! Very soft, extremely well made, confortable, they stay up well but aren't too tight anywhere... they are just perfect. I strongly recommend this product.

UPDATE: My son has been wearing Ecoland underwear for nearly 2.5 year now, and they wash and last extremely well and are consistenly very comfortable for him. They really are superbly made and excellent quality cotton.
