Five great Osprey rucksacks

I like the Osprey brand. They are smart with their designs and make rucksacks to suit different activities, for men and women and in a range of sizes. Here are five of the best. For walking Osprey Aura 35: Women’s fit with good ventilation and comfort and a host of features and all wrapped up in two funky colours. Also comes in size 50l. Osprey Xenith 75: For longer hiking adventures, the men’s fit Xenith offers comfort and joy despite being larger and packed with a wealth of features. The ventilated back system is particularly good. For cycling Osprey Momentum 30: Perfect for shorter trips and for the daily commute. The AirScape back system offer stability and great ventilation. There’s also an internal hydration sleeve and a useful LED bike light attachment point. Osprey Escapist 30: For days when the riding is longer or demands more spare clothes and food. The 30l capacity offers more volume but still doesn’t detract form comfort. This pack also includes the high quality AirScape back system. For running Raptor 10 for women and men: A different fit to suit different physiques and perfect for running off-road. There’s an integrated three-litre “Hydraulics™ reservoir and plenty of space for a couple of spare layers, energy snacks and all your bits and pieces.
