Hiking Backpack Naturehike Helium Series 25L Polyamide AIR Mesh Hydration-Ready Black

Hiking backpack Naturehike Helium Series 25L is an ultralight daypack built from polyamide fibre and polyethylene fabric for high-strength, abrasion-resistant performance on trail and in demanding outdoor environments. The shell fabric features a water-repellent treatment that limits moisture penetration during light rain and damp conditions. The pack uses a professional AIR breathable honeycomb mesh back system with a three-dimensional cushioning pad that creates an air channel between the pack and the wearer’s back to dissipate heat and moisture during sustained physical activity. Adjustable chest and waist straps stabilise the load during uphill sections and uneven terrain. The 25L volume is sized for full-day hikes, short overnight trips, and active travel, with a dedicated hydration compartment, hiking pole attachment, and emergency whistle integrated into the chest buckle.

Features

• AIR breathable back system: Honeycomb mesh back panel with 3D cushioning pad creates an air channel to dissipate heat and moisture during active use.
• High-strength fabric: Polyamide fibre and polyethylene shell abrasion-resistant, scratch-resistant, and puncture-resistant for use in thorny and rocky terrain.
• Water-repellent treatment: Shell fabric treated to resist moisture penetration during light rain; YKK waterproof zippers with rubber strips prevent water ingress at closures.
• Hydration system compatible: Independent water bag compartment with hose routing hole supports hydration reservoirs for hands-free drinking on trail.
• Multifunctional storage: 3 compartments, 3 pockets; hiking pole attachment, lamp lanyard at base, external glasses strap on shoulder, emergency whistle on chest buckle.
• Dimensions and weight: Packed size 50 29 16 cm, weight approximately 600 g.
• Adjustable carry system: Padded shoulder straps with chest and waist buckles for load stabilisation during uphill and technical terrain.

The Naturehike Helium 25L is well suited for full-day hikes on the Latvian Coastal Hiking Trail (Jras taka) between Ragaciems and Kolka, where exposed coastal sections alternate with forested dune terrain over 2030 km daily stages. The AIR honeycomb mesh back panel maintains airflow between the pack and the wearer’s back during sustained walking in warm conditions, reducing heat build-up on long flat sections without shade. When coastal wind and light rain develop, the water-repellent shell and YKK waterproof zippers limit moisture penetration into the main compartment during short precipitation events. The 25L volume accommodates a 2-litre hydration reservoir, food for a full day, a wind layer, and a basic first aid kit within the 600 g pack weight.
