The Spider backpack is an astounding result of a daring experiment that has yielded a fruitful amalgamation of a high-tech tough body and all the features of a practical bag. Armed with an edgy and stimulating design, Spider is an embodiment of the farsighted vision of the designers at Spencer and is a culmination of what was perhaps at one point only a dream. The innovative Spider is an ideal manifestation of the off-road notion and is without doubt the evolution of an amalgamation of technology and looks, between material elements and quality standards. The Spider backpack features an amazing tractability of the various spaces internally that makes it instantly adaptable and transform itself to accommodate oxygen bottles, perhaps the most unwieldy of accessories and all the bags of medical supplies required to be carried.
