First Layers One Piece In Organic Cotton is rated 4.7 out of 5 by 10.
Rated 3 out of 5 by from Not the traditional Hannah's that I love. Don't get me wrong, there's nothing actually wrong with this shirt. It's just a normal shirt with great eco friendly fabric. But that's not the reason why I buy Hanna. Hannah fabric is usually thick and stands up to rough wear . It can be handed down over and over again. This shirt is thin and stretchs out. It lacks the cuffs which allow for easy sleeve rolling up. It lacks the snaps on the shoulder. And it lacks the double crotch snaps that allowed baby's two sizes worth of growth. My family is large and has a rotating closet of baby clothes that passes from baby to baby. The thick Hanna shirts from 10 years ago made it through 4 babies. These thin shirts will not be joining them. Please bring back the thick fabric and sturdy cuffs!

Rated 4 out of 5 by from One of the BEST onsies out there Snaps on the shoulder, two rows of crotch snaps. Soft and thick good quality. I find these are the best.

Rated 5 out of 5 by from Ideal tee for baby Bought these for my granddaughter.....I also bought some of the tees in the short sleeve.....I like the way they fit and she feels comfortable in them. They do not bunch up and the their are two rows of snaps at the bottom to allow for growth.....she gets lots of wear out of these....super soft too.

Rated 5 out of 5 by from So worth the wait I am now on second generation of Hannas. My children wore them and now my grandchildren. Nothing compares. I only wish I knew where my kids Hannas went? I must have handed them down because they never wore out. I loved the shirt with the snaps on the neck. My boys wore theses all the time. They were a bit heavier cotton. Delicious. This pink body suit is perfect.... it is the most beautiful shade of pale pink. Glad I said yes to the wait.

Rated 5 out of 5 by from The perfect staple piece These are the most perfect layering onesies. They are very lightweight and perfect to wear on a sunny but breezy day, or perfect to layer under a sweater without making my son too hot. A must have for any baby!

Rated 5 out of 5 by from Softest onesie you'll ever buy for your baby! I love this onesie! I can't say enough great things about it because it is so soft and light. Great for wearing alone or under sweaters. I will definitely be getting more!

Rated 5 out of 5 by from Excellent Bodysuit These onsie/bodysuits are the absolute best there is. Wide neck to accommodate baby's head (also useful for not showing under sweaters/outfits), super soft and free of any harmful chemicals. While I don't buy strictly organic clothing for baby, I like knowing that the layer closest to him is free of dyes, chemicals, etc. He wears these onesies (both in short and long sleeve) under everything. Long-lasting (we have hand-me-downs!) and stain resistant. Simply the best.
