Patagonia’s MLC is a travel bag that can backpack, duffel, and sometimes briefcase depending on the generation. The public constant is the 45L name and the Black Hole fabric story.
Because Patagonia refreshes this SKU, we refuse to hard-code a gram weight from an old catalog. Open the current page and copy the spec table if you are updating this plate.
Shortlist reason: a carry-on claim baked into the name plus a written guarantee program. Not claimed here: a lab waterproof rating we did not measure.
