The F-Stop Guru 4 Air 24-liter backpack in Arctic color has been designed for male users with a specialized torso adjustment system. This 24-liter capacity backpack features advanced ventilation technology with an air-mesh back panel that promotes air circulation and reduces moisture buildup during extended use. The main compartment offers organized storage with multiple internal pockets and dividers, suitable for camera equipment, outdoor gear, or daily essentials. Made from durable, water-repellent materials, the backpack maintains its structural integrity and provides protection against light rain. The external dimensions are approximately 50 cm in height, 30 cm in width, and 20 cm in depth, with a total weight of around 1.2 kg when empty. Multiple external attachment points include compression straps, gear loops, and side pockets for added storage flexibility. The shoulder straps and hip belt feature ergonomic padding designed for comfortable weight distribution during hikes or travel. Internal organizational elements include padded dividers that can be reconfigured to accommodate various sizes and shapes of equipment. The zippers utilize weather-resistant construction, while the reinforced bottom panel offers increased durability when placed on rough surfaces. The color scheme combines bright Arctic gray tones with contrasting black accents for practical visibility in outdoor environments. This backpack model is the successor to previous Guru series versions, featuring improved ventilation and material upgrades while maintaining the core functionality of the F-Stop product line.
