Backpacks that are too big or too small can be a nuisance. To achieve the greatest convenience, most people own more than one backpack so that they always have the right size at hand. The TIOLIpacks battle this problem with detachable compartments. The wearer can add or subtract these compartments based on how much room they need. While a little bulky when full, the TIOLIpack provides an alternative to backpacks with detachable daypacks. One of these packs costs backers $90 for a two-compartment backpack with an August 2014 delivery date. TIOLI hopes to raise $4,400 in its 31-day Kickstarter campaign.
