■ Sports brand technology thoroughly supports your fatigue reduction. Features of 'TIGORA SLEEP'
'TIGORA SLEEP' (general medical device) is recovery wear developed by Alpen, which has been involved in sports for over half a century. It aims to reduce various fatigue accumulated by moving the body—from light running and stretching to full-scale training and matches—and to maximize performance the next day. It firmly cares for fatigue accumulated not only in sports scenes but also from daily work and household chores while you sleep. It has been well-received as a product that supports fatigue reduction along with comfortable sleeping, and has sold a cumulative total of 240,000 units as a sports brand's recovery wear.
This product has been notified as 'Household far-infrared blood circulation promotion clothing', which is classified as a general medical device designated by the Minister of Health, Labour and Welfare.
As for its performance, the fabric embedded with special ceramics radiates far-infrared rays emitted from the human body, promoting blood circulation. As a result, effects such as fatigue reduction, alleviation of muscle tension and stiffness, and reduction of muscle fatigue can be expected.
This product has been featured in many media outlets, starting with winning the Grand Prize in the Recovery Gear category of the 'GoodsPress AWARD 2025' by the product information magazine 'GoodsPress' (Tokuma Shoten) in December 2025. Designed from the perspective of a sports brand, it was evaluated for being a sleep-specialized product that supports fatigue reduction along with comfortable sleeping.
