Spectre 12W Womens Running Hydration Backpack

The Oxsitis Spectre 12W Trail Hydration Backpack is designed for female trail runners and long-distance hikers who require reliable hydration, storage, and comfort during demanding adventures from long trail runs to ultra-trails. Featuring a shape adapted to the female form, this 12-litre hydration pack provides an ergonomic fit that supports natural movement while maintaining excellent stability. Shoulder cut-outs help prevent chafing, while the positioning of the side panels is designed to improve comfort and support. The ventral and chest adjustment system allows a secure personalised fit without compressing the chest, and the high-positioned design helps reduce irritation around the lumbar area. Combining technical materials, intelligent organisation, breathable construction, and adaptable carrying systems, the Spectre 12W delivers lasting comfort and performance over long distances and challenging terrain.
