These baby bonnets, in classic European style, are made from 70% organic merino wool and 30% silk.  

A baby's head radiates a great deal of warmth through their head, without the protective covering of hair that children and adults have.  With a baby bonnet, babies can more easily maintain their body temperature. This is especially important when the temperature fluctuates.

• These baby bonnets are made from 70% organic merino wool and 30% mulberry silk.  These natural fibers breathe and moderate the temperature against baby's skin.
• Merino wool is the softest of wools, with thin fibers that do not itch.
• Pure silk is like a second skin.  It is softly soothing and can have a calming effect.
• The textile in these baby bonnets are hypoallergenic and especially designed for sensitive skin.  They have a natural stretch. 
• The ties on these caps are very long - 14 inches - they can easily be snipped and knotted at the ends, to your desired length.

Sizing

European sizing correlates with baby's length in centimeters.  1 inch = approx 2.5 cm.  Age range should fit well.  The hats have some stretch to them, and will often fit beyond the age range.  

• 50/56  (0-3 mo.) = 19.5 in / 22 in
• 62/68  (3-6 mo.) = 24.5 in / 26.75 in
• 74/80  (6-12 mo.) = 29 in / 31.5 in

To maintain the health and longevity of your garments, organic wool is best washed by hand.  Many modern woolen items are treated with chemicals to allow them to tolerate machine-washing.  Certified organic wool does not contain such chemicals.  Some washing machines have a special wool-cycle, which maintains a lukewarm water temperature throughout the wash and rinse cycle, as well as minimizing agitation of the garment, which can lead to felting/shrinking.   See Caring for Wool.
