Atheneum Classic Training Shorts The Atheneum Classic Training Shorts are designed for movement without distraction. Balanced, durable, and intentionally minimal. Built for jiu-jitsu, grappling, and high-intensity training, these shorts are offered in two configurations: a streamlined shell or a version with an integrated compression liner. Both are constructed from premium performance materials and engineered to hold up through daily training. Liner Option The integrated compression liner provides added support and stability during extended sessions. It helps reduce muscle fatigue, improves comfort under pressure, and eliminates the need for separate base layers, allowing you to focus entirely on the work. Shell Option The liner-free version offers maximum freedom and a lighter feel. Ideal for athletes who prefer layering flexibility or a more traditional training short. Construction & Performance Both versions feature: Durable, abrasion-resistant fabric Reinforced stitching for long-term wear Secure, non-slip waistband Lightweight, quick-dry material to keep you comfortable through hard rounds The design is clean and understated, making the Classic Shorts equally at home in the training room or outside the gym. Fit Notes Athletic fit with full range of motion. True to size.
