The 20L Drysak is our solution for keeping dirty/damp items like shoes, dirty laundry, swim trunks, and towels separate from your clean/dry belongings inside your bag. Put those dirty/damp items inside the drysak, then put the drysak inside your pannier or duffle. It packs tiny when not in use and weighs almost nothing.
Wanted a decent quality drysack as sort of a “belt and suspenders” solution to keep some critical items dry even in torrential downpours. These things do the trick. At a price that is less than other premium brands. Very happy with them!
On a recent ride of the Colorado BDR I ran in to extremely heavy rain, then hail. I bailed to a nearby campground only to find thatmy waterproof bag (of another brand) did not have waterproof zippers. On this trip I had stuffed my camp pillow into my Drysak and thank goodness I did. It kept me from a miserable night in wet sleeping gear. My bags panniers always perform but the little things the Mosko Mot Drysak and tie down straps while little items make a big difference.
Waiting on the Scout 60 duffle so I don't have this problem again.
Two dry sacks were used for clean clothes. They worked awesome. I stacked two horizontal in a 35 l pannier.
