### ⭐⭐⭐⭐⭐ Warm, cozy, and economical...
*by M***N on September 8, 2014*

I put off buying this thing for 6 months, due to price, and now I wish I hadn't waited.Apparently, in order to keep babies from going up in flames, infant sleepers have to be either fleece (which stops being fluffy after only 3 washes), treated with fire resistant chemicals (um, no), or snug fitting (itchy!). Well, I was cheating by buying super big sleepers for my son, and just letting him sleep with floppy footies. Unfortunately, now that he is 9 months, the "snug fitting" sleepers are ridiculously tight, and he was waking up with freezing feet every night, even the fleece sleepers-- which are 20 bucks a pop where I live, and have to be replaced every month, because they pile up. Plus, he started crying whenever I zipped them up, because who on EARTH wants to sleep in a compression sack-- I certainly wouldn't. I itch when my tank tops are too tight!So I finally pressed the button and got this little gem. I've used wool baby products before, so I would encourage anyone to "lanolinize" this every few months, which helps the wool resist moisture/pee, softens it, and allows you to wash it less, and makes it hang dry quicker. However, this is as soft as Egyptian cotton and the company says it's washable, so you don't really need to. (I always handwash with a little Dr. Bronners and lanolin, though, personally).This bag has sturdy snaps (no scratchy velcro), which allow it to be comfy but form fitting on the upper body. Double snaps on the side comform to a smaller or bigger baby. Even though my son has TONS of room in the foot area to grow into, I have zero concerns that he will get twisted up in it... and he's a hard-core squirmer. Even with his constant caterpillar scooting and rolling, he's never complained or been uncomfortable in this, and when he does wake up at night, his feet are WARM, because he's basically sleeping in a giant mitten. It has a zip at the bottom for nighttime changes or, possibly, if you're kiddos feet are getting hot. There's an open/close spot at the crotch area for safety belts to go through. Plus, this saves money, because (underneath) the baby is sleeping in the same one-sies or shirts he/she would be using during the day, so you don't have to keep getting longer foot-ie pyja, or replacing the scratchy fleece ones.Don't hesitate to buy this wonderful product. It's cozy, quality construction, and economical, in the long run.Update: still going strong at 2 years, with occasional washing, but no special treatment whatsoever. It's even been thrown in the regular, high heat dryer several times, although I wouldn't recommend doing so regularly. My son sees the sack and knows it's time to "snuggle up" for bedtime. Love it!

### ⭐⭐⭐⭐⭐ Love our Woolinos, well worth the price.
*by J***N on July 5, 2024*

The best product for infants who can no longer be swaddled. The material is soft, high quality wool. Incredible easy to put the baby in; with the ability to grow as the child grows.We use this for camping, stadium events, family outings. Anything where our child is going to be out past bedtime. The car seat strap holes are fantastic and help to keep the body temp regulated in any climate.Very long lasting material, be sure to read the wash directions! A wool safe detergent and hang dry or hand cleaning.

### ⭐⭐⭐⭐⭐ Grows with kid, all seasons, awesome material!
*by A***R on July 19, 2025*

I love the product! The material is awesome, it is simple to put on baby, even changing of diaper at night is not really disrupting the sleep, there is a thermometer which helps you what baby should be wearing under, it fits to baby until 2 years, no troubles with ‘tog’.
