Materials and Construction
63% Recycled Makrolon Polycarbonate Shell
The exterior shell is made from high-performance Makrolon polycarbonate containing 63% recycled content. This material is known for its exceptional impact resistance and flexibility — it absorbs shock from rough baggage handling while maintaining structural integrity.
Unlike heavier plastics, polycarbonate provides strength without excessive weight, helping keep overall luggage mass manageable for checked travel.
ZeroLiner Interior System
Osprey's ZeroLiner interior eliminates excess material layers, reducing weight and maximising usable packing volume. This design:
- Improves packing efficiency
- Reduces overall case weight
- Maintains structural durability
- Allows easy wipe-clean maintenance
It reflects Osprey's lightweight-first engineering approach.
Aluminium Dual-Pole Trolley System
The ultralight aluminium trolley handle provides rigid, stable steering under heavier loads. Dual-pole construction improves control and long-term durability while keeping weight down.
Two adjustable height settings ensure ergonomic handling for users of different heights.
Hinomoto Silent Run 60mm Dual Spinner Wheels
Premium Japanese-engineered Hinomoto Silent Run wheels deliver:
- Smooth, low-resistance rolling
- Reduced vibration and noise
- Enhanced long-term durability
The four-wheel dual-spinner configuration improves weight distribution and allows 360° upright movement with minimal effort.
Bluesign-approved Divider Fabric
Interior divider panels are constructed from bluesign® approved, 100% recycled 210D nylon with a PFAS-free DWR finish. Bluesign certification ensures responsible chemical management and reduced environmental impact during production.
YKK EYL #10 Zippers
Abrasion-resistant, large-gauge YKK EYL #10 zippers provide dependable closure strength and long-term durability through repeated travel cycles.
Features
Lightweight Hardside Protection
Durable recycled polycarbonate shell protects contents from impact and compression while remaining lighter than many traditional hardcases.
TSA-Approved Travel Sentry Lock
The integrated lock secures belongings while allowing authorised airport security inspections without damage, eliminating the need for external padlocks.
Four-Wheel Mobility System
Four 60 mm Hinomoto Silent Run dual spinner wheels provide stable, quiet and effortless 360° manoeuvrability — even when fully packed.
Dual-Height Aluminium Trolley Handle
Custom dual-pole handle enhances steering precision and adjusts for ergonomic comfort.
ZeroLiner Weight-Optimised Interior
Maximises interior packing space while reducing unnecessary structural weight.
