Why We Like It

This lightweight, full-feature daypack that performs just as well as similarly-designed packs – but for a fraction of the price. The Flash 22 excels in comfort and versatility, giving you plenty of space and organization for all your daily essentials without taking a toll on your shoulders. An internal hydration sleeve makes it a great option for day hikes or festivals. The rucksack and drawstring closure offers good security without compromising accessibility.

The packability, however, remains to be improved. Fortunately, I've found that by removing the rigid back insert you can greatly reduce the size of the pack when compressed, although this can be a pain to do over-and-over. Overall an excellent choice for a larger-capacity travel daypack.

Tip: When traveling in theft-prone areas, pack your valuables in a packing cube and attach it to the hydration loop at the top of the inside of the bag with a gear tie. That way if someone tries to "slash and grab" the contents of the pack they won't get away with the important stuff.
