These pajamas are great for warm weather--they're footed, but manufactured with lightweight material.  They have a grip-surface on the feet so your kiddo won't slide on smooth surfaces.  For some reason, zippered pajamas are difficult for me to find, so these are great.  I use these for my son, and my husband and I both agree that the purple is not so striking as to seem inappropriate on a boy (not that either of us is terribly concerned about that, but some parents may be).
