Very stylish and comfortable stretchy knit. 100% thick cotton. It is also very popular among civilians. Very stylish and comfortable. The cut and pattern of this shirt gives the illusion of broad shoulders and a thin waist, on both small and large bodies. Ideal Russian Souvenir – Russian Military Telnyashka! Ideal as an undershirt for sailors, fishermen and outdoorsmen. This one is summer type, but It is also a great as underwear in winter! It is a very good original army shirt of high quality, not a cheap made-in-China fake. I guarantee you will love this shirt! Would be a great gift for anybody!
