Care & Details

Machine wash cold on a gentle cycle with a mild detergent and hang to dry. Avoid fabric softener — it coats the fibres and stops muslin from softening. Skip the hot wash and the hot dryer: high temperatures are what cause shrinkage.

Muslin is a natural, slightly elastic weave, so small size variations are normal. Measurements are taken at full stretch.

What is Muslin Cotton?

A fabric with a long history

Muslin came out of ancient Bengal, where it was woven so finely that it was nicknamed "woven wind". It was light enough to pass through a ring and strong enough to outlive the person who bought it. The weave we use today is the same idea: fine cotton yarn, loosely woven, layered for substance.

Why muslin is worth it

  • Breathable by construction — the open weave moves air instead of trapping it, so it stays comfortable in a heated apartment and in August.
  • Softer every wash — muslin doesn't start at its best. The fibres relax with each cycle and the fabric keeps improving for years.
  • Gentle on skin — 100% natural cotton, hypoallergenic, and free of harsh finishes, which is why muslin is the standard for babies' skin.
  • Stronger than it looks — the layered weave resists pulls and holds its drape.

Take 100 nights to decide. If it isn't right, email support@borealloom.com with your order number and we'll arrange a return, exchange or store credit.

Materials

Made from Pure Muslin Cotton

A relaxed two-piece in 100% natural muslin cotton. The open weave means it doesn't cling when the room is warm and doesn't feel thin when it isn't — which is the whole problem with most sleepwear. Sizes M to 3XL, in White, Pink, Yellow and Light Green.

THE PROCESS

How our Muslin is Made

  • Close-up of raw white cotton bolls in a shallow pale wooden bowl on a workbench.

    It starts with the boll

    Natural cotton is harvested, cleaned and spun into fine, even yarn. No synthetics, no blends — just cotton.

  • Close-up of cream cotton yarn running through a loom weaving an open multi-layer muslin gauze.

    Then it gets woven

    The yarn runs through looms set to an open, multi-layer muslin structure. That open gauze is where the breathability comes from.

  • Folded stacks of freshly washed cream muslin fabric on a pale wooden table in a finishing workshop.

    Washed and finished

    Every piece is pre-washed, then checked by hand before it ships. Soft on arrival, softer with every wash after.

The lightweight cotton muslin breathes well through warm nights and feels almost weightless against my skin

The elastic-waist shorts stay easy and comfortable while sleeping, without feeling tight around my waist.

I especially appreciate the soft finish without scratchy seams or labels during long nights.

The cotton muslin has become softer after washing, while still keeping the relaxed shape of the set.

The short sleeves and breathable muslin work just as well for slow mornings as they do for bedtime.

OUR STORY

Made for the warm side of the door

Boreal Loom began in Vancouver in 2019, in the middle of a long, wet winter — with one blanket, and one question: why shouldn’t everyday comfort feel this good?

Every piece since has been chosen for a moment rather than a specification. The evening on the sofa. The slow morning. The cold night that stays outside.

Because when it’s cold out there, what happens in here matters more.

Frequently Asked Questions

Machine wash cold on a gentle cycle and hang to dry. Skip the fabric softener and the hot dryer. Muslin is one of the few fabrics that genuinely improves with washing — it gets softer every cycle.

Yes, and that's the main reason we use it. The open weave lets air move through instead of trapping it, so it cools you in summer and holds warmth in winter without ever feeling stifling. In a Canadian home that goes from -20 °C outside to overheated inside, that matters more than raw thickness.

Both are cotton, but muslin is woven in an open, multi-layer structure. That makes it breathable, hypoallergenic and gentle enough for sensitive skin and for babies. Unlike synthetics it doesn't trap heat or hold odour, it regulates temperature naturally, and it softens with age instead of pilling and breaking down. It's also free of harsh chemical finishes, which is a healthier choice for the people who actually sleep under it.

It's cut relaxed on purpose — sleepwear should not be fitted. Take your usual size. If you're between two, size up; muslin relaxes further after a couple of washes.

It works right on this page. Pick the Buy 1, get 1 free bar and choose the colour and size for each of the two items; pick Buy 2, get 2 free and you choose four.
