What everyone is saying
"It's a life changer for baby and parent""Can't say enough good things about the Woolino. It's a life changer. She instantly started sleeping thru the night. The baby is nice and cozy in it, super soft and never scratchy, and just try to get her to sleep the night without it. You'll want two."
– Dan Kon
"Worth Every Penny""Absolutely love this, wish I could give 10 stars. The only sleep sack we use now, baby stays the perfect temp, not too hot or cold and the temperature varies here in New York during fall, winter and spring. Worth every penny."
"Best Sleep Sack Ever!""After several months of use with my 1 year old daughter, I have decided that the Woolino is by far my FAVORITE piece of baby gear. I wanted a bag that could handle the fluctuating temperatures of Ohio all while keeping my daughter comfortable. This is the ONLY bag you'll ever need, from basically 60 degrees to 80 degrees. Plus the material is soft, light weight, made with quality workmanship, and is very easy to care for. My only regret is that I didn't purchase the Woolino sooner and wasted money on inferior infant bags of several different tog & sizes."

"by far the best baby purchase we made""...by far the best baby purchase we made. Cold out? No problem. Hot out? No problem. Won't leave home without it. Our 16 month old has been wearing it every night since about 5 months."

"How do I love thee, woolino? ""Let me count the ways...I first purchased one out of desperation when my eczema coated son was so sensitive to polyester that all the warm pjs were making him scratch to bleeding. I bought the woolino as a last resort. It is worth it's weight in gold. It adjusts beautifully, stays on and keeps baby the perfect temp."
– A. Hendrickson
"EVERY CHILD SHOULD HAVE""This is a must have!! Baby is comfortable--- no need to worry about varying temperatures because the merino is for all climates (i.e.: keeps baby warm in winter and keeps baby cool in summer) its wonderful!! … All other sleep sacks are miles behind this one."
– Emma Son
"Worth EVERY penny!""Our 8 month old son, who had been having noticeable temperature drops in the night, despite extra layers of PJs, and who had been waking up 2-3 times a night his entire life began sleeping from 8:30pm-7:00am upon introducing the Woolino! He calms down as soon as we put it on him and often times is not ready for us to take it off! HIGHLY recommend and very well worth the money!"

"Love Our Woolinos""We LOOOOOOOVE our Woolinos. I am recommending them to all my friends - my only wish is that I had found them for my first daughter. I spent so much wasted time fretting over Togs!!! 0:)"

"Believe the Hype""Game changer for my one year old sleeping through the night. ...I'd pay double for the magic this bag works."
– Michael B. Jones
"Love the Woolino Sleep Sack""I've put my baby boy into the Woolino sleep sack every single night since he has been 4 months old. Not once has he woken up because he was too cold or too hot. It is incredible! It has become part of our bedtime routine. He knows when he gets in his sleep sack, it is time for 'nigh nigh'. I am up at least twice during the night to check on him, and he always is sound asleep, at what feels like a comfy temperature. The quality of the material is top-notch! It has held up for almost a solid year of use, and it shows not a single sign of wear! Thank you Woolino for such an awesome product!"
