Our Woolino Ultimate 4 Season Baby Sleep Bags are designed so that you need only one – regardless of the season, regardless of your baby’s age.

How do we do that?

The merino wool we use is supremely breathable, keeping your baby warm when it’s cold and cool when it’s hot. That temperature regulation means that your baby will sleep comfortably throughout the night, year-round – and that means a better night’s sleep for you too.

Our universal sizing means that it will fit a baby from 2 months to 2 years. This consistency in sleepwear will allow your baby to always associate the comfort of their sleep bag with a good night’s sleep.

So, instead of buying a different sleeping sack for different seasons, as well as buying larger ones as they grow, you just need one Woolino sleep bag for your baby.

• 100% Natural
  Pure silky-soft hypoallergenic merino wool lining and the finest organic cotton outer.
• 4 Season use
  Unlike other brand sleep sacks that come in either winter or summer weight/TOG rating, the Woolino 4 Season Sleep Bag can be used year-round. It’s suitable for room temperature 63-77F (17-25C). Because of Merino’s unique ability to regulate body temperature, it helps keep your baby warm when it's cold and cool when it's hot.
• Grows with your baby
  It has a universal size so it can be used for babies 2 months up to 2 years old. And for smaller babies, simply close the underarm snaps to adjust the fit.
• Excellent value
  With Woolino Ultimate 4 Season Sleep Bag, you don’t have to buy a different wearable blanket every few months. It is the only baby sleep bag your baby will need, in winter or summer, until they turn two years old.
• Designed to be practical
  It features double shoulder snaps and a two-way side zipper, so it opens up completely flat for easy dressing without waking the baby! For easy nighttime diaper changes, you can open the bottom only. It also has zipper-pull guards to protect baby's skin and to discourage them from chewing on the zipper pull.
• Travel friendly
  A closable seat-belt opening allows for easy transfer between stroller, car seat and crib, so you can keep your baby’s sleep routine intact while on the go.
• Easy care 
  In addition to Merino being naturally anti-bacterial and odor repellent, Woolino sleeping bags are machine washable and can be tumble dried on a 'no heat' setting. See care instructions here.
• It is a safer alternative to loose blankets
  Helps your baby stay covered through the night and replaces loose blankets in the crib that can cover your baby’s face and interfere with breathing. The sleeping bag also promotes back sleeping.
• Naturally fire-resistant 
  Wool is a natural flame retardant and the best fiber to have next to your baby’s body. Woolino sleep bags meet all US CPSC children safety requirements.
• Certifications
  Woolino 4 Season Sleep Bags are made with Woolmark and Oeko-Tex 100 certified merino wool and GOTS and Oeko-Tex 100 certified organic cotton. We use nickel, lead, and phthalates free YKK snaps and zippers, which are also Oeko-Tex 100 certified.
• Free Nursery Thermometer with a dressing guide included.
• Awards
  #1 rated and #1 selling merino wool baby sleep bag in US and Canada and winner of Mom's Choice Award, Creative Child's 2012 Top Choice of the Year Award, Green Scene Mom Award 2016, 2017 Eco Excellence Award, and Baby Maternity's 2018 Top Choice Award.

Merino wool by nature is self-cleaning and does NOT need to be washed as frequently as other fabrics. To refresh and reduce washing, turn garment inside-out and air often. Follow care instructions carefully to ensure you get the best possible wear from your garment.

Merino Wool Sleep Bags and Clothing

• It is not necessary to wash your Woolino garments prior to use
• WE SUGGEST MACHINE WASH: Close all zippers. Use gentle wool cycle, on LOW temperature, 100°F /40°C max. Gentle spin
• If hand wash: Gently soak and squish in lukewarm water. Do not agitate, wring or rub wool against wool
• Use wool approved detergent - we recommend Kookaburra, a plant based alternative to "traditional" detergents
• Do not soak or bleach
• Avoid fabric conditioners and softeners
• Use minimal amount of detergent as it can increase felting and pilling over time
• Sleeping bags can be tumble dried on “NO Heat” setting. Close zipper before tumble drying. Dry flat whenever possible. Keep away from direct sunlight or any direct heat source (radiator). Do not tumble dry blankets and clothing.
• Cool iron on outer cotton only. Do not iron prints or labels

Pilling - How to prevent it

Pilling is a natural process that is inherent in merino fabric due to the fact that merino is a staple fiber. Generally, pilling occurs because the shorter fibers are working their way to the surface of the fabric.

The best way to avoid pilling is to wash a new merino wool product after the first couple of wears. The pilling will diminish over time as non-tenacious wool fibers work themselves free of the fabric and break away.

Lambskin rugs 

• Please note that when washed, sheepskin products will not come out looking like new. We recommend only spot cleaning when possible. Sponge off small, lightly soiled areas and towel dry where necessary. Daily airing is recommended to keep the lambskin fresh
• Use gentle or wool cycle (max 38°C/100°F)
• Use a mild detergent, we recommend Kookaburra, or use biodegradable wool washes and shampoos with natural pH. Do NOT use soap or washing powders containing enzymes or bleach. Do NOT use fabric softeners. Do NOT use common laundry detergents
• Gently stretch the product back into its original shape
• To dry, place the lambskin on a flat surface. Keep out of direct sunlight. Do NOT place the lambskin on a radiator or in front of a convector or heater
• Lamb-fleece may be brushed lightly after washing to help restore their soft fluffy appearance
• Dry-cleanable
• Do NOT bleach
• Do NOT iron

Comforters 

• We recommend only occasional washing or spot cleaning when possible. Sponge off small, lightly soiled areas and towel dry where necessary
• Use gentle, wool cycle or wash on Low (85°F)
• Use a mild detergent, we recommend Kookaburra, or use wool washes and shampoos with natural pH. Do NOT use soap or washing powders containing enzymes or bleach. Do NOT use fabric softeners
• Do NOT tumble dry
• Dry-cleanable
• Do NOT bleach
• Do NOT iron

To freshen up the comforter, expose it to direct sunlight and fresh air for a couple of hours every few months.
