Testimonials

Can't say enough good things about the Woolino. It'sa life changer. She instantly started sleeping throughthe night. The baby is nice and cozy in it, super soft andnever scratchy, and just try to get her to sleep the nightwithout it. You'll want two.

Dan Kon

Absolutely love this. Wish I could give 10 stars. The onlysleep sack we use now, baby stays the perfect temp,not too hot or cold and the temperature varies here inNew York during fall, winter and spring. Worth every

penny.

Phannyon

Best Sleep Sack Ever! Woolino is by far my FAVORITEpiece of baby gear. I wanted a bag that could handlethe fluctuating temperatures of Ohio all while keepingmy daughter comfortable. This is the ONLYbag you'llever need...

K. Wrighton

..by far the best baby purchase we made. Cold out? Noproblem. Hot out? No problem. Won't leave homewithout it. Our 16 month old has been wearing it every
night slnce about 5 months.

Danielle Hillon

Every child should have one. This is a must have!! Babyis comfortable - no need to worry about varyingtemperatures because the merino is for all climates(i.e.: keeps baby warm in winter and keeps baby cool insummer). It's wonderful!!... All other sleep sacks aremiles behind this one.
