Collection: Long white T-shirts

Long white T-shirts from Undiemeister

Smarter, stylish and unmatched in comfort

You know the drill: your favourite T-shirt that's too short after two washes. Or that creeps up while moving, leaving you constantly trying to straighten your clothes.

But it doesn't need to be this way. With the long white T-shirts from Undiemeister you choose exactly what you are looking for: extra length, a timeless white colour and a fit that stays put.

Slim fit or regular fit, this T-shirt works with you. So you can go about your day the way you want: comfortably, neatly and confidently.

No creeping up T-shirt, no visible base layer, just: the T-shirt that stays where it belongs.

Why long white T-shirts are a smart choice

Long T-shirts are essential for men who:

• Move around a lot and don't want to constantly pull or straighten their T-shirt
• Wear a layered outfit where the T-shirt is allowed to stick out just a bit
• Are looking for a longer under layer that is not visible under shirts
• Prefer comfort and length in one stylish piece

The extra length not only provides functionality but also a stylish, modern look, especially when combined with a slim fit.

The secret behind comfort and fit

Undiemeister's long white T-shirt is made from our exclusive Mellowood blend:

• 68% TENCEL™ Modal

• High breathability, ideal for warmer days
• Temperature regulation, warm when needed, cool when possible
