Mystery Ranch's T-100 backpack is a great choice for those looking for a heavy and durable pack. It has a long strap to buckle down the entire load, two hood pockets, sizable 'bullet' pockets, roomy H2O pockets, and a separate compartment at the bottom for storing items. It is also adjustable and comes in a variety of colors, making it suitable for a range of activities. However, some users have experienced issues with the buckles and zippers, as well as the lack of a bladder pocket.
