Thank you for viewing our product from among many others. We are introducing a compression T-shirt. By maintaining proper posture, you can utilize muscles you haven't used before, resulting in unconscious exercise effects. It suppresses muscle vibration and enhances training effects with correct posture! Point 1 Ergonomic design! Arms, shoulders, chest, and abs are all firmly compressed! This product allows you to achieve an ideal body shape through compression. It may be difficult to put on at first, but once you wear it, you'll definitely feel comfortable. Point 2 Pursuit of quick-drying & breathability! Polyester 65%, nylon 30%, spandex 5% - the golden ratio. Nylon & spandex are used in areas where you sweat, ensuring comfort at all times. Point 3 Safe and secure double-stitched construction! It can withstand intense movements and achieves elasticity and a perfect fit based on ergonomics. It's the perfect product for training♪ Product Details Size: L size [M] 60kg-70kg, 170cm-175cm [L] 70kg-80kg, 175cm-180cm [XL] 80kg-90kg, 180cm-190cm Material: Polyester 65%, nylon 30%, spandex 5% Color: Black ※The appearance may differ slightly depending on the pixel count and device. Also, please note that imported products may not meet the quality standards of Japanese products. This product is a full-fledged compression training shirt. Those who have never done muscle training may find it difficult to breathe and may not be able to wear it for even 5 minutes. This shirt intentionally pumps up through compression, so you may not fully appreciate its benefits unless you are a serious trainer or have a certain level of exercise awareness. Of course, if you are just starting out, it will put a load on your arms, chest, and abs in a short period, leading to muscle hypertrophy in a short time. #Training #Gym #Compression #PumpUp #ShortSleeves #TShirt
