Good bag. Is new and light. Has carry handle/strap tab on bottom as well. Only complaint is once I squeeze air out it slowly leaks in after half a day. I don’t know if they all do this.

Easy to carry, hard to dismiss.

A perfect small capacity drybag. Weighs almost nothing and when empty takes up very little space. Proven watertight and great for hanging food.

Just what we needed for packing items in canoe & 'yaks. Hold alot of stuff, new, priced right. Used this past weekend in 'yaks-- after a few biffs, our items stayed nice & dry.

Buy more than you think you'll need.

Not because they are bad, but because they are good and i keep finding applications where I need another one, and another one. They perform well in the field, and the price is right.
