The Secumar Ultra 170N Semi-Automatic Lifejacket is a comfortable and extremely user-friendly lifejacket for water sports enthusiasts who want plenty of freedom of movement on board. This model falls into the 150N class and provides an actual buoyancy of 165N, making it ideal for use with light clothing during recreational boating, sailing and general use on the water. Thanks to the patented folding technique, the jacket remains extra flat, even at the neck, ensuring it fits close to the body and hardly gets in the way when moving or working on deck. The soft fleece collar prevents chafing at the neck and noticeably increases comfort, especially during longer trips. Thanks to the SECUMAR snap fastener, you can simply pull the jacket on like a normal coat, making it easy to use and practical.

The Ultra 170N comes as standard with many clever details that enhance safety and ease of use. For example, the jacket features a cross strap, inspection window, stowage strap, mouth valve, signal whistle and the patented SECUMATIC 4001S inflator. Through the window in the protective cover, you can check at a glance whether the inflator and CO2 cartridge are ready for use. The single-chamber buoyancy chamber provides reliable support in emergency situations, whilst the polyamide protective cover gives the whole unit a neat and durable finish. For users wishing to further expand their kit, options such as a splash guard, emergency light and inflator lock are available. This makes this model a strong choice for anyone looking for a lightweight, comfortable and robust automatic lifejacket without unnecessary bulk.
