I notice that the quality of the new t-shirts is improved. There was nothing wrong with the old ones which were among my favorites. But the new ones are softer and more comfortable, and I like the enlarged logo of the warrior on the front.

Systema clothing is professionally subtle. Not flashy, but strong without being loud, with dignity of design and presentation.

The T-shirt has a very nice and comfortable feel. I think the material is softer but it’s still strong quality. I washed my shirts several times and the painted logo still keeps the colors.
The enlarged Systema logo got recognized from far away now.
Nice improvement.

As a performing artist, runner and coach of both, I am profoundly aware of the relationship of mind and body – when it comes to fine tuning this integration, Systema Breathwork is invaluable in the way it teaches us through direct experience that less tension is truly more power!
