Are you climbing Ben Nevis or battling through the Highlands and islands then I recommend the Greenland Top 20 L Backpack. This is a tough bag from Fjallraven . It follows all the brands history of being stylish and long lasting thanks to the brand\'s tough G-1000 Heavyduty eco material. This can really take a hammering from snow to wind to the city\'s dirt and grease. Easy to recommend! Greenland Top 20 L Backpack Storm 20L Hardwearing, water-resistant G-1000 HeavyDuty Eco. Laptop sleeve with padded base (up to 15 inches). Recycled polyester, organic cotton. Large zippered pocket on the front, covered by the top lid. Zippered pocket in the top lid. Side pockets for drinking bottles etc. Straps and metal hooks keep the top lid in place. Spacious main compartment with snow lock. Description by Cameron
