The Beaker Dry Bag is for those who want a fully seam-taped, waterproof dry bag that protects your gear just as well as it organizes it. Semi-translucent so you can easily see inside, the sides of this bag are lined with liter measurements for calculating the volume of your gear. A roll-top closure makes it easy to pack down and seal tight.*Note - this product is non submersible and not intended to protect electronics from water damage.
