【Supervised by a Practicing Physical Therapist × Ergonomic Design】 Our arm holder was developed under the supervision of a practicing physical therapist, a professional in human anatomy. We pursued both a "natural fit" and "comfortable wear," thoroughly researching the shape of the arm and wrist, muscle movements, and even daily life actions. Utilizing specialized knowledge and experience cultivated in the field, we have adopted a support structure that evenly distributes the weight of the entire arm. It is a design that provides peace of mind for those who need to wear it for extended periods due to rehabilitation, fractures, or sprains. It is designed to be used on either the left or right arm and is suitable for both men and women, fitting a wide range of body types. 【Significantly Reduces Shoulder and Arm Strain with a 3-Point Support Structure】 In response to concerns like "My shoulders get stiff when I wear an arm holder..." and "My neck hurts...", we have adopted a 3-point support structure that balances the support of the shoulder, elbow, and thumb. It reduces the burden on the shoulder and neck compared to traditional arm slings, making it less tiring even after prolonged use! The shoulder pad is a thick, approximately 8.5cm wide design that effectively distributes pressure on the shoulder. Furthermore, a thumb support is provided at the wrist to prevent the arm from slipping and maintain a stable posture. 【Easy to Put On with One Hand! One-Touch Buckle】 We have also thoroughly focused on ease of use in daily life. We have adopted a one-touch buckle structure, allowing for easy attachment and detachment with a single "click" even with one hand. The strap has an adjuster that allows you to adjust the length with one touch to fit your body size and clothing. With a smooth operation like a seatbelt, anyone can easily achieve a perfect fit. You can use it comfortably during rehabilitation, when going to the hospital, when going out, and even when sleeping. 【Gentle on the Skin and Excellent Breathability!】 To ensure comfort without stuffiness even during long periods of wear, we have used "soft gauze material" on the inside and "breathable mesh material" on the outside. It is gentle on the skin, allowing even those with sensitive skin to use it comfortably. We have also focused on weight reduction, eliminating waste down to the gram. Elastic gauze is used on the elbow to fit the curve of the arm securely. It is an arm holder that can be used comfortably all season long, regardless of the season.
