SISU started in late 2009 with a single vision in mind: “to enrich peoples lives both mentally and physically by evangelizing the life changing benefits that CrossFit offers”. Our entire team’s DNA is made up of former athletes with the same vision. CrossFit SISU is a purpose-driven organization, and we have quickly become the West Metro’s largest and leading CrossFit affiliate by offering a refreshing change to people seeking Community, Challenge and Coaching.

CrossFit SISU, at its core, is about the hard truths of life. Sustainable results don’t come easy. We foster a fresh perspective. Accepting this fresh perspective for change takes inner strength. Strength takes guts. To have “guts” is SISU…

At SISU, we are committed to delivering premium quality fitness clothing that stands the test of time. Our products are crafted to not only meet but exceed your expectations for durability, comfort, and performance.

Our Lifestyle tees, while not designed for intense workouts, are printed on Comfort Colors garments, utilizing 6.1 oz., 100% ring spun USA cotton. We prioritize sustainability by using sustainably and fairly grown USA cotton and sewn with USA cotton thread. These tees are not only stylish but also environmentally conscious, making them a staple in your everyday wardrobe.

For those rigorous workout sessions, our performance line is the best of durability and functionality. Our performance tees, pullovers, and jackets are all made to withstand tough workouts while keeping you comfortable. Our "Performance Tess" Crafted from 100% premium polyester with a fabric weight of 0.12 oz/yd² (4 g/m²), these pieces are soft and moisture-wicking, ensuring you stay dry and focused. They are fade and snag resistant, meaning they maintain their quality wear after wear. The relaxed fit allows for unrestricted movement, while UPF44+ protection shields you from harmful UV rays. Reinforced shoulder seams and double-needle stitch hems ensure long-lasting durability, making these pieces your go-to choice for any active pursuit.

With SISU, you can trust that our fitness clothing will not only last you a super long time but will also become your favorite attire for all your workouts, runs, hikes, and more.

At SISU, we prioritize quality and sustainability, which is why all of our orders are made to order. This means your product is crafted especially for you as soon as you place your order, rather than sitting in bulk inventory. By producing on demand, we reduce overproduction and waste, so thank you for making thoughtful purchasing decisions!

Typically, orders will arrive within 7 business days. However, please keep in mind that delivery times may vary during holiday seasons, store sales, or other peak periods. We appreciate your patience and understanding as we work to deliver your order promptly while maintaining our commitment to quality products and customer service.
