Hiking Backpack Naturehike Helium Series 30L+5L Polyester AIR Mesh Expandable Hydration-Ready Black

Hiking backpack Naturehike Helium Series 30L+5L is a lightweight expandable daypack designed for long-distance trekking, climbing, and multi-day hiking where carrying capacity and pack weight are both critical factors. The base capacity of 30 litres expands to 35 litres via a 5-litre adjustable expansion system, providing flexible storage for varying kit loads across different trip lengths. The pack weighs approximately 1.1 kg and is constructed from durable polyester fabric with waterproof and breathable properties to protect contents during rain while allowing moisture to escape during sustained physical activity. The AIR breathable honeycomb mesh back panel with 3D cushioned support creates an air channel between the pack and the wearer’s back to reduce heat build-up during long hikes. A supportive waist belt transfers load from shoulders to hips, reducing fatigue on extended routes.

Features

• Expandable 30L+5L capacity: Base volume 30 litres expands to 35 litres via adjustable expansion flexible storage for day hikes and short overnight trips.
• Lightweight construction: Approximately 1.1 kg pack weight for a 30L+ volume designed for long-distance trekking and climbing where base weight matters.
• Waterproof and breathable polyester fabric: Shell material resists rain penetration while allowing moisture vapour to escape during high-output activity.
• AIR breathable back system: Honeycomb mesh back panel with 3D cushioning creates an air channel to dissipate heat and moisture during sustained hiking.
• Ergonomic load distribution: Waist belt transfers weight from shoulders to hips; adjustable shoulder straps with chest buckle for load stabilisation on uneven terrain.
• Hydration system compatible: Dedicated hydration sleeve with tube outlet for hands-free drinking on trail.
• Functional details: Emergency whistle on chest buckle, external webbing for gear attachment, side mesh pockets, shoulder strap pockets, side hand straps.

The Naturehike Helium 30L+5L is well suited for multi-day hiking on the High Tatras ridge trails in Slovakia, where daily stages of 2030 km combine sustained ascent, exposed ridgeline sections, and variable alpine weather. The expandable 5-litre extension allows the pack volume to be adjusted between a lighter day configuration and a fuller load when carrying additional layers, food, and emergency equipment for high-altitude routes. The AIR honeycomb mesh back panel maintains airflow during steep ascent sections where heat build-up is a consistent factor, while the waist belt reduces shoulder fatigue over consecutive high-output days. The waterproof polyester shell limits moisture penetration during the short but intense precipitation events common in alpine environments above 2000 m.
