For this 6ft 1in tester, the M/L size fit perfectly, enabling the comfortable hip belt to take the weight in exactly the right place. Both of these materials are treated with PFAS-free DWR (durable water repellent) to encourage water to bead off the fabric and provide reliable water resistance for unpredictable weather; however, please be aware that this doesn't make it fully waterproof! Materials are also recycled, which of course, is much better for the planet, and bluesign® approved. bluesign® approval ensures strict pollution control and consumer safety standards are met through manufacturing. The Hikelite utilises components from their Airspeed™ system to offer premium comfort and support when wearing it. The Hikelite 28 has a traditional panel loader design and a zip that leads you to the main compartment, which has plenty of room for lunch, extra layers and other essentials you usually take for a day on the hill. In fact, it easily swallowed my entire winter kit list including bothy bag and extra layers, so I have no doubt that it’ll offer enough space for any day hike you plan.
