Looking for something in the 15-20 Liter per side size, anybody know of any? I saw the HT Imnaha which are 13.8L per side but that is just a little too small. I did a search and the most recent small pannier thread was from 2015 with like 4 replies, and nothing helpful except soft luggage suggestions. I know I need 15-20 Liter per side because I currently use a 40 Liter soft luggage set up. Thanks in advance for any pointers.
