Warm linings: micropolar, fleece and sherpa

Posted by Caroline Ouellet on

What is a good understudy?

Provides a good degree of warmth

Good breathability: You can add more than one layer without breaking a sweat if you need more warmth.

A good lining will not keep bad odors.

Allows good flexibility depending on the garment and its use.

Good long-term washing durability. Will not fluff or discolor or worse, develop dark circles (from sweat for example).

Dries quickly and maintains their thermal power even when wet.


  • Lighter lining but offers more breathability
  • 100% Polyester
  • - 200 gsm
  • Fairly thin and flexible
  • Soft
  • Stretchable, especially horizontally
  • Heather charcoal gray micropolar is a blend of two yarns and its texture makes it different from other micropolars. It is much more stretchy, despite having the same weight as the other shades.
  • Lined hats, underwear, tracksuits, comforters, accessories, mittens, slippers, bathrobe, pajamas, etc...


  • 100% polyester
  • + 200 gsm
  • Thick to very thick
  • Hotter
  • Variable expandability, sometimes not even expandable at all
  • Warm hats (aviator style for example), tracksuits, comforters, accessories, mittens, slippers, dressing gown, pajamas, etc...


  • 100% polyester

Micropolar vs polar

The important difference is the weight of the fabric! The micropolar must be under 200 gsm while the polar will be above 200 gsm up to 400 gsm.

While we see a certain consistency in the texture and general extensibility of microfleeces (apart from the charcoal gray which is different from the others), polar fleeces are made with several very different aspects, whether in terms of their density, their stretchability, horizontal, vertical or even non-stretchable, their weight, their thickness or their texture.

We therefore consider fleece warmer than microfleece. However, microfleece wins out on flexibility and stretch and is therefore the big winner for more detailed projects, such as fitted lined beanies or sports underwear (the combined as we say in the Lower St. Lawrence near us!) Polar fleece will be an excellent choice as a tracksuit, the traditional sweater of the same name that we wear over our clothes to go outside on cool days.

micropolar vs sherpa

Polar tek / Polar performance

  • 100% polyester
  • Average weight
  • Hotter
  • Good breathability
  • Stretchy and flexible
  • Sportswear, bathrobes, hoodies, outerwear


To avoid :

fabric softeners! They help reduce the breathability of the fabric.

put too much detergent, or add bleach

heat: we do not iron micropolar, fleece and sherpa. We also avoid drying at high temperature in the machine or drying too long. Synthetic fibers are flammable and can melt under the iron.
