Product Details

Bamboo and merino wool baby sleep sack in Heather Lake Blue. We created Canadian-made bamboo and merino wool baby sleep bags to be the softest, safest & most cuddly wearable blankets for your child, ever.

Great sleep starts with the best sleep garments for your baby. Just like our bamboo and merino wool LoveLuxe sleep bags, to keep them safe and cozy at the same time. 

  • Ethically made in Canada, always 🇨🇦
  • Bamboo is hypoallergenic, sustainable, and moisture-wicking, helping to keep your baby comfortable and dry 
  • Merino wool is ultra-premium, soft, lightweight, moisture-wicking, and warm
  • Silky smooth & super soft to spoil your loved little one
  • Tagless for added comfort and protection against baby’s skin
  • 2-way zipper for no-fuss diaper changes 
  • Naturally odour-resistant
  • Made with non-toxic dyes
  • Zipper tab pocket for safety and convenience
  • Oeko-Tex 100 certified fabrics
  • Incredible durability that will look and feel new, wash after wash
  • Our premium fabrics are naturally stretchy for the ultimate in comfort, practicality and flexibility 
  • Shell: 86% bamboo rayon, 9% merino wool, 5% spandex (for stretch, performance, warmth and super-cuddly-snuggly-softness)
  • Lining: 66% bamboo rayon, 28% cotton, 6% spandex
  • Fits true to size (sizing up is not necessary for most babies)


Once you touch and feel our LoveLuxe bamboo and merino wool products, you’ll never look at another sleep sack the same. 

Bamboo LoveLuxe+ Merino sets the bar for softness, breathability, durability, comfort and performance.

Silky smooth, super soft, and completely luxe to spoil the little ones in your life that you love to pieces. 


Bamboo is hypoallergenic and moisture-wicking, helping to keep your baby super comfortable and dry on those hot days and nights.

Merino wool is super soft (not itchy, like other wool), anti-static, lightweight, durable, and wicks away moisture (just like bamboo rayon!) to deliver the ultimate in performance. 

Its natural odour-resistant properties always keep your LoveLuxe+ pieces free of any unwanted smells - and we’ve designed our products to last for generations.


When it comes to your baby, their health and safety is priority number 1. That's why we meticulously designed each and every aspect of our sleep bags with safety in mind.

We only use the most premium and high-quality fabrics in our wearable blankets and have incredible attention to detail for things like 2-way YKK zippers and zipper tab pockets, tagless neck labels and Oeko-Tex 100 certified materials. Learn more about sleep safety here

Perfect gift

Got this gift for my nephew as he grew out of his other ry&pen sleep sack and he loves it!

Silène Rennicks (Gatineau, CA)
Super soft and great temperature control!

I love how soft and luxurious this sleep sack is! The only minor change I would make is the zip. It only zips up - there’s no way to have the zipper heads at the bottom of the sleep sack when it’s closed. Other than that, this is my favourite sleep sack, and I’ve used many kinds for my 2 kiddos! 1.0 TOG is perfect for us, since we keep the room at around 20C and have a long sleeve sleeper on baby underneath.

Sarah (Moose Jaw, CA)
Great, just a small zipper issue

Has held up well through many washes, baby seems cozy in it. My only complaint is that the zipper doesn't like to stay all the way zipped up, and now there is a small hole in the zipper cover. For the next round of sleep sacks made, I'd like to see a bit more room there so that the end of the zipper isn't rubbing a hole through.

Win Win!

We received 2 sizes as Christmas gifts for our 8 month son. The fit is perfect around the neck and arms with loads of room to grow! The quality of the fabric is luxurious and soft and washes up beautifully! The key selling point for purchasing as a gift was that they’re made in Canada!
Win Win!

Christmas gift

This is a Christmas gift to my grandson so it hasn’t been opened up yet but will certainly have a report very soon.
Merry Christmas to Ry & Pen 🎄
