How to identify quality silk pajamas?

Not all silk pajamas are created equal.

Two models may look very similar in a photograph while offering vastly different quality, comfort, and durability.

Before investing in silk pajamas, there are several objective criteria that can help evaluate a garment's quality.

The type of silk, its momme weight, craftsmanship, finishes, and certifications directly influence the daily experience.

Whether you're looking for your first pair of silk pajamas or want to invest in a durable piece, this guide will help you make an informed choice.

8 Criteria for Quality Silk Pajamas

Criterion	Why is it important?
Mulberry silk	Long fibers, softness, resistance
Fiber quality (Grade 6A)	More regular and durable fibers
22 momme	Better longevity
Seams and finishes	Garment longevity
Buttons	Durability and elegance
OEKO-TEX® Certification	Textile tested for harmful substances
Fabric drape	Elegance and comfort
Cut	Freedom of movement and durability

Now let's look at each of these criteria in more detail.

1. Prioritize genuine mulberry silk

The first criterion is undoubtedly the most important.

High-end pajamas are usually made from mulberry silk, recognized today as the global standard.

Produced from silkworms fed exclusively on mulberry leaves, it features long, regular, and particularly strong fibers.

Its qualities are numerous:

• exceptionally soft touch;

• excellent breathability;

• natural temperature regulation;

• good long-term resistance;

• discreet and refined luster.

Beautiful silk does not seek to shine excessively. Its luster is natural, subtle, and elegant.

2. Not all mulberry silks are identical

Grade 6A: a superior quality indicator

The mention "mulberry silk" is an excellent starting point, but it alone is not enough to guarantee a garment's quality.

Not all mulberry silks have the same level of regularity or the same characteristics.

Grade 6A is generally considered the highest quality level for mulberry silk. It refers to fibers selected according to demanding criteria of regularity, cleanliness, and homogeneity.

This superior quality contributes in particular to offering:

• a more regular fabric;
• a particularly soft touch;
• a more natural luster;
• better long-term resistance.

Not all brands specify the grade used. When indicated, it is generally an excellent indicator of quality.

3. Understanding momme weight: the momme

The weight of silk is expressed in momme (mm).

The higher the momme number, the denser the fabric.

• 16 momme: light, often used for certain accessories;

• 19 momme: excellent compromise between suppleness and hold;

• 22 momme: the high-end standard for durable pajamas.

Weight	Ideal use
16 momme	Pillowcases, accessories, scarves
19 momme	Bed linen, nightgowns, light clothing
22 momme	Pajamas, evening wear, pieces designed to last

Momme weight is therefore not a question of "better" or "worse," but of use. A lighter silk is perfectly suited for a pillowcase, while pajamas benefit from a higher momme weight to offer more hold and durability.

22 momme silk offers several advantages:

• better wear resistance;

• more elegant drape;

• a feeling of quality from the first touch;

• superior lifespan.

Contrary to popular belief, a high momme weight does not mean the silk is warmer.

Silk remains naturally thermoregulating.

4. Observe the quality of the finishes

Details often reveal a garment's quality.

Take the time to observe:

• the regularity of the seams;

• the piping connections;

• the cuffs;

• the hems;

• the collar finishes.

Clean and regular seams not only improve aesthetics but also the garment's longevity.

A well-made pair of pajamas will retain its shape much better over the years.

5. Buttons are more important than you think

Buttons play a full part in the quality of pajamas.

Natural mother-of-pearl buttons are particularly appreciated for:

• their elegance;

• their feel;

• their resistance.

They generally age much better than plastic buttons.

It's these small details that often distinguish a high-end garment.

6. Check certifications

Pajamas are worn for several hours directly against the skin.

The OEKO-TEX® Standard 100 certification guarantees that the textile has been tested for numerous undesirable substances.

Even if this certification does not directly measure the quality of the silk, it is a reassuring benchmark for the consumer.

7. Observe the fabric's drape

Beautiful silk is immediately recognizable by its movement.

It naturally follows movements without appearing stiff.

The fabric glides delicately over the skin.

Its luster remains discreet.

Excessively shiny silk is often less refined than silk with a more natural reflection.

8. Choose a cut designed to last

Quality does not depend solely on the material.

The cut also plays an essential role.

Good pajamas naturally follow movements.

They don't constrict the shoulders.

They don't pull at the knees.

They remain comfortable both at bedtime and upon waking.

Timeless cuts elegantly transcend seasons.

Comfort: an often overlooked criterion

Beyond technical characteristics, quality silk pajamas provide a very particular sensation.

The material follows the body's movements.

It naturally limits friction.

It helps maintain a pleasant temperature throughout the night.

This comfort explains why many people who have adopted silk then find it difficult to go back to other materials.

How to compare two pairs of silk pajamas?

If you're hesitating between several models, ask yourself these questions.

✓ Is it made from genuine mulberry silk?

✓ Is the momme weight indicated?

✓ Is the fiber quality specified?

✓ Are the finishes visible?

✓ Do the buttons seem high quality?

✓ Is a certification mentioned?

✓ Are the care instructions clearly explained?

The more positive the answers, the more likely the garment is to offer a good experience over time.

The most common mistakes

When buying silk pajamas, certain mistakes are common.

Avoid in particular:

• choosing solely based on price;

• confusing satin and natural silk;

• ignoring momme weight;

• neglecting finishes;

• forgetting to check certifications.

Conversely, a high price does not automatically guarantee better quality.

It is always advisable to observe all criteria.

Why are some silk pajamas much more expensive?

The price depends on many factors:

• the quality of the silk;

• the fiber length;

• the momme weight;

• the craftsmanship;

• the finishes;

• quality controls;

• certifications.

Two pairs of pajamas may look very similar in a photograph while having significant differences in comfort, strength, and durability.

In the long run, a well-designed garment often proves more durable than a regularly replaced entry-level model.

In summary

Before choosing silk pajamas, check these essential criteria:

✓ genuine mulberry silk

✓ fiber quality (Grade 6A when specified)

✓ appropriate momme weight (22 momme for excellent durability)

✓ regular seams

✓ quality buttons

✓ OEKO-TEX® certification

✓ fluid and elegant drape

✓ comfortable and timeless cut

Quality silk pajamas are not distinguished solely by their appearance.

They are recognized by the quality of their material, their craftsmanship, and the pleasure they provide, night after night.

Choosing quality silk pajamas means choosing a piece that will accompany hundreds of evenings and mornings.

More than just nightwear, it's an essential that you look forward to wearing, year after year.
