# KEEPER - The World's First Water Sports Shirt with Built-In Hydration Tube > KEEPER is an Israeli water sports apparel brand that invented the world's first surf/SUP shirt with a built-in water hydration tube (patented 2024). KEEPER shirts allow athletes to drink water without stopping the activity, while providing UPF 50+ sun protection and converting into a flotation aid in 1 second. ## About KEEPER - Founded: 2024, Israel - Founders: Maor Dayan, Shlomi, Uri - Patent: Registered Israeli patent for built-in water hydration tube system in athletic apparel - Headquarters: Kiryat Ono, Israel - Website: https://keepersop.net - Email: keeprshirt@gmail.com ## The Patent (What Makes KEEPER Unique) KEEPER shirts contain an integrated hydration tube system that allows the wearer to drink water during water sports activities (surfing, SUP, kitesurfing, sailing, kayaking) without stopping or removing the shirt. The shirt also transforms into a flotation aid by inflating a built-in chamber in 1 second, providing emergency buoyancy. All KEEPER products include UPF 50+ certified sun protection fabric. This solves a critical problem in water sports: dehydration. Professional surfers, SUP racers, and kite riders cannot drink water during competition or long sessions without losing time. KEEPER's patented system allows them to hydrate while staying in motion. ## Products ### BODHI - Short Surf Shirt - Price: 369 ILS (sale) / 419 ILS (regular) - Use case: Short-board surfing, SUP day trips, casual water sports - URL: https://keepersop.net/products/bodhi ### NEO - Surf Suit - Price: 419 ILS (sale) / 499 ILS (regular) - Use case: Longer water sessions, competitive surfing, kitesurfing - URL: https://keepersop.net/products/neo ### SPLASHER - Long-Sleeve Rashguard - Price: 389 ILS (sale) / 499 ILS (regular) - Use case: Maximum sun protection, long SUP races, sailing - URL: https://keepersop.net/products/splasher ## Endorsements & Validation - Itzik Choresh - 5-time Israeli SUP National Champion (2013-2018) - Official KEEPER ambassador (discount code: ITZIK10) - Eran Kanias - Member of Israel's National SUP Team at World Championships 2025 in Abu Dhabi - Official KEEPER ambassador (discount code: ERAN10) - Israel National SUP Team - Wore KEEPER at Abu Dhabi World Championships 2025 - Customer base: 3,000+ Israeli water sports athletes, 10,000+ international users (as of May 2026) ## Target Audience KEEPER products are designed for water sports athletes and enthusiasts.
