The Gelert Wilderness Rucksack includes several models in a line that is specifically designed for hikers and explorers of the wild outback, high-countries of the mountains and the badlands.  The rucksack is constructed of Ripstop Polyester, making it the perfect companion for hikers, no matter what the terrain. If the backpacker gets caught in the rain, it is no problem for the Gelert. It includes a rain cover and comes in a yellow color for easy spotting if an emergency arises. The wilderness pack features numerous small pockets to keep valuables easily accessible during storms and unexpected events that can occur on an adventure in the wilderness.

The Gelert rucksack comes in six models. The base model pack is twenty-five liters.  It is compact and ideal for small day trips on which a hiker may stow rain gear, a few emergency necessities, and a packed lunch. The next model size is a thirty-five liter rucksack. The added space makes this sack perfect for a weekend trip. It can store an A-frame tent, food for three or four days and a change of clothes. For longer, more adventurous trips, the Gelert line offers the forty-five or the fifty-five liter sacks. The extra room accommodates more winter gear, larger tents and technical gear need for the mountains or wilderness, such as climbing gear. The next size in the line is sixty-five liters. The extra liters are merely a bonus and the space can be used to carry a variety of items.

The final variation in the Gelert Wilderness Rucksack line is the granddaddy of all rucksacks – the eighty-five liter mega-sack. This beauty has so much room it accommodates enough supplies for a two-week long outdoor adventure. This rucksack is obviously designed for seasoned voyagers or a cross-country journey. The only possible issue with this sack is packing food that won’t spoil; however, if a hiker is using this sack; more than likely the food issue has already been solved.
