Small and smart: the PURE 4 has everything you need from a backpack and nothing you don't. We pared it back to the essentials you'll need on shorter tours without having to carry extra weight. It's hydration system-compatible with outlets on both sides for the drinking tube, while mesh pockets in the main compartment keep everything neatly organised and are great for stashing bars, multi-tools and other small items. A side zip pocket keeps your smartphone or other essentials safe and within easy reach. We also incorporated our X-Shape shoulder system that fastens across the chest, so the backpack stays comfortable and stable without cutting into your stomach, leaving you to breathe freely while you sweat the climbs or rail the trails. The backpack also features the versatile MOLLE system, so it's easy to securely attach the small CUBE GEAR BAG 1 using the integrated touch fasteners for practical extra storage.
