About the original
SealLine makes waterproof cases and roll-top dry bags for paddling, kayaking, and backcountry use and is a division of Cascade Designs, the Seattle-based outdoor-gear manufacturer founded in 1972 and best known for the Therm-a-Rest inflatable sleeping pad and MSR stoves. The SS2020 Supreme collab version is an 8.5-by-4.5-inch case in transparent polyurethane with an oversized SealLock pressure-sealing zipper and a loop for a wrist lanyard — the same case SealLine sells as the HP Map Case, sized to hold a passport, phone, wallet, or small electronics. It released May 28, 2020 at $48 with a box logo printed on the front.
About SealLine
SealLine is an American waterproof bag maker founded in 1985 in Seattle, Washington as part of Cascade Designs, the outdoor manufacturer started by former Boeing engineers in 1972. SealLine introduced its dual-strip roll-top closure in 1986, originally for the maritime industry before kayakers and rafters adopted the bags.

Cascade Designs also owns Therm-a-Rest, MSR, and Platypus, and manufactures most SealLine products in its Seattle and Cork, Ireland facilities.
