Ultimate Zero-G Performance

The engineered square grid construction creates a constant air gap that prevents fabric adhesion to the skin, transforming the base layer into an active pump that redistributes heat and eliminates cold sweat during sustained physical load. Base 90 represents the thinnest, most advanced moisture-management system for high-intensity operations.

 

Why Base 90?

The Base 90 is designed as an ultra-fine, highly functional first layer, ideal for missions exceeding 24 hours where changing clothes is not an option. Its unique ribbed knit architecture creates square spaces that prevent the fabric from sticking to the skin. This "point contact" ensures perfect moisture transfer while remaining incredibly light and non-restrictive.

Where you will appreciate it most

Long-duration operations

High-intensity movement

High-intensity movement, as the material actively prevents overheating and rapid cooling by wicking sweat away instantly.

Layering

Layering under any clothing, especially for those with sensitive skin, thanks to the extra-fine microfiber material.

How to properly care for your t-shirt?

To make your t-shirt last as long as possible and keep its unique properties, it is necessary to follow a few basic rules. Proper care extends the life of the fiber and saves your investment.

Wash at 40 °C

Wash on a regular program. A temperature of 40 °C is ideal for removing dirt and bacteria.

Do not bleach

Chemical bleaches damage the fiber structure and color stability.

Do not tumble dry

High temperatures in the dryer can irreversibly damage elasticity and functional zones.

Do not iron

The material is naturally wrinkle-free. Ironing is not necessary and could burn the fiber.

Do not dry clean

Use only regular detergents (ideally for functional underwear).

No fabric softener

Important! Fabric softener coats the fibers, clogs pores, and the t-shirt stops wicking sweat.
