A trunk suitcase has a deeper, more vertical shape than a traditional suitcase. This gives you more structured packing space, especially for longer trips, bulkier items and layered organisation. It is ideal when you want generous capacity without the wide, flat feel of a classic large suitcase.
Where Purpose Becomes Innovation. → Designed as a System.
Developed under 83 Openwater patents, E-Tec™ defines a modular engineering system — designed to adapt over time and reduce the need to replace entire products.
ULTRA-SILENT ROLL
Designed and patented by Openwater, the precision-engineered Energy-Smooth® wheels deliver ultra-smooth, whisper-quiet performance on any surface.
Energy Tec® is engineered with standardized fittings and a modular architecture, making repairs simple and efficient — allowing key components to be replaced with precision, extending product life and reducing unnecessary waste.
MOTION LOCK
Open Water wheels are engineered with Energy-Stop®, an integrated locking mechanism that easily clicks into place to prevent wheel rotation when stationary — delivering instant stability and controlled release when you’re ready to move.
Energy Tec® is engineered with standardized fittings and a modular architecture, making repairs simple and efficient — allowing key components to be replaced with precision, extending product life and reducing unnecessary waste.
MODULAR INTERIORS
Flow Scene® is Openwater’s modular interior platform — fully replaceable and exchangeable to extend product life and adapt to changing travel needs. Crafted from recycled, dope-dyed, certified polyester, it combines responsible material innovation with smart organization and precision fit, keeping your luggage fresh, functional, and built for the long run.

ZIPPED SECURITY
Energy Lock® combines a reinforced double-coil zipper, precision Unicast pullers, and an integrated TSA-approved lock into one seamless security system — engineered for strength, smooth operation, and confident protection wherever you travel.
Energy Tec® is engineered with standardized fittings and a modular architecture, making repairs simple and efficient — allowing key components to be replaced with precision, extending product life and reducing unnecessary waste.
MODULAR DESIGN
All components are engineered to be easily repaired, replaced, or serviced when needed. This modular construction extends the lifespan of the product while reducing unnecessary waste. As part of the Energy Tec® platform, every element is designed with accessibility and long-term performance in mind — allowing key parts to be maintained or exchanged without replacing the entire suitcase.
