Long sleeve bamboo T-shirt for men and when it is enough

Short answer: A long sleeve T-shirt is enough on its own indoors all year and outdoors in spring and autumn. Outside in the cold it is a layer, not a solution.

On its own indoors

In an ordinarily heated room a long sleeve T-shirt is enough all year. It gives coverage without the warmth a jumper adds. See bamboo long sleeve T-shirt for men.

As a layer under a shirt

A thin long sleeve under your shirt gives warmth without building up on the shoulder. That works better than a thicker jumper on top. See bamboo T-shirts for men.

Sleeve length

The sleeve should end at the wrist. If it ends mid forearm, it gets pushed up and stays there, and the shirt looks too small.

Under a sweatshirt

Two thin layers insulate better than one thick, because the air between them holds the warmth. See sweat clothing.

Washing and length

Jersey shrinks most in the length. A shirt that only just reaches down becomes too short after hot drying. See washing and care.
