These roll-top haulers provide dry-bag protection with the space savings of a compression stuff sack. The bags are 30 percent lighter than their predecessors—the 15-liter bag we tested weighs only 5.1 ounces—thanks to a new waterproof fabric made of TPU-laminated nylon.
A band of waterproof/breathable fabric around the bottom releases air as the bag is compressed. Available in 10-, 15-, 25- and 35-liter sizes. $35 to $49; 3.2 to 6.6 oz.; outdoorresearch.com
