  • Compare those measurements with the ranges in the table below.
  • Pick the row your measurements fall inside.
  • Between two sizes? Go with the larger one for a more relaxed fit.

Care & Details

Machine wash cold or warm on a gentle cycle with a mild detergent and tumble dry low. Avoid bleach and fabric softener. Iron on a low setting if you want a crisper finish.

Cotton relaxes slightly after the first wash. Wash cold and dry low and it will hold its size.

Why 100% Cotton?

One fibre, no compromises

Most textiles at this price are cotton blended with polyester, because polyester is cheap and holds a press. It also traps heat and holds odour. We use cotton on its own.

What that gets you

  • It breathes — cotton moves moisture away instead of sealing it against your skin.
  • It stays comfortable at both ends of the year — no clammy feeling in summer, no static in winter.
  • Hypoallergenic — natural fibre, no harsh finishes, safe for sensitive skin.
  • It ages well — cotton gets more comfortable with use rather than breaking down.

Shipping is free on every order to Canada, with no minimum spend. All orders are processed in 1–3 working days on average and then shipped out to anywhere in Canada.

Every order ships with a track & trace link. Parcels are declared so you should not be asked for customs duties — if you ever are, send us the receipt and we'll refund it. We currently ship to Canada only.

THE DIFFERENCE

Why 100% Cotton Changes Everything

  • Close-up of clean white cotton fibre being spun into long-staple yarn on a spinning frame.

    Pure fibre

    Harvested cotton is cleaned and spun into long-staple yarn. No polyester, no filler.

  • Close-up of cotton yarn on a loom, weaving a smooth even plain-weave fabric.

    Woven for feel

    The yarn is woven at a density chosen for softness and airflow rather than for the highest possible thread-count number.

  • Folded stacks of pre-washed white and stone-grey cotton fabric on a pale wooden bench.

    Washed before it ships

    Every piece is pre-washed so it arrives soft and stays true to size.

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 or warm on a gentle cycle and tumble dry low. No bleach, no fabric softener. Iron on low if you want a crisper finish.

Yes — no polyester, no blend. Blending in polyester makes fabric cheaper and helps it hold a press, but it also traps heat and holds odour. Pure cotton breathes, stays comfortable across the year and gets better with use.

Everything is pre-washed before it ships, so any relaxation has already happened. Wash cold and dry on low and it will hold its size. Hot water and a hot dryer are what cause shrinkage in natural fibres.

Both are 100% cotton. Muslin is woven open and layered, so it's airier and softens dramatically with washing. This is a standard cotton weave: a little more substantial, a little more structured, soft from day one.

Shipping is free anywhere in Canada. Orders are processed in 1–3 working days and travel for 6–10 more, so most arrive within 8 to 14 working days with a tracking link. See our Shipping Policy for the full detail.

Every Boreal Loom order is covered by our 100-Night Guarantee. Use it, wash it, live with it — and if it isn't what you reach for, email support@borealloom.com within 100 nights of delivery and we'll arrange a return, exchange or store credit.
