Soft Nightwear – What Makes Nightwear Soft?

Short answer: The softness of nightwear is decided above all by the fibres. Bamboo viscose has fine, smooth fibres with no scratchy ends, which is why bamboo nightwear feels markedly softer against the skin than ordinary cotton nightwear of the same thickness and weight.

The fibres decide the softness

The skin does not register the name of the material, but the pressure from individual fibre ends. If the ends are many, short and stiff, the fabric reads as rough. If they are few, long and flexible, it reads as soft. Softness is a count of fibre ends.

Why bamboo viscose is the softest

Cotton is spun from short seed hairs, and every hair ends somewhere on the surface of the yarn. Bamboo viscose is spun as one long filament, so there are far fewer ends to feel. See the soft models under bamboo night tops for women.

The knit can ruin a good fibre

Even a smooth fibre can be knitted hard and dense, and then the fabric turns stiff whatever the material. A looser knit leaves air between the yarns and a softer surface against the skin. That is why two sets in the same fibre can feel entirely different.

The weight against the skin

A heavier fabric does not feel harder but calmer, because it lies still instead of following every movement. Bamboo viscose is heavier than cotton jersey at the same thickness, and that is part of why the same model is experienced as softer.

Seams and labels matter a lot

A hard label at the neck or a thick side seam is felt more clearly than the fabric itself when you lie in one position for eight hours. Look for flat seams and a woven label in the side seam. That is the detail most people regret afterwards.

Softness that lasts

Because the softness comes from the shape of the fibre and not from a treatment, it does not wash out. A set in bamboo viscose feels much the same after twenty washes, as long as it has not been in the tumble dryer. See the range under nightwear.

Fabric softener is a shortcut

Softener lays a smooth film on the fibres and feels soft at once. The price is that the film slows moisture transport and locks in odour, and moisture transport is exactly what nightwear has to do. The softness also disappears again after a few washes.

For the men's range

The same rules apply on the men's side, where the cuts are made for a different shoulder and a different length. See the models under bamboo nightwear for men, and check the neckline and seams rather than only the fabric. See also bamboo regulates temperature and washing guide for bamboo clothing.

Frequently asked questions

Why does bamboo feel softer than cotton?

The fibres are longer and have fewer ends at the surface. It is the number of fibre ends the skin reads as rough or soft, not the name of the material.
