Genuine Mystery Ranch product, bought directly from an authorized dealer in 2020. These are getting very hard to find now that MR was acquired by Yeti and discontinued everything besides their tactical products.
Here are the original specs:
Most summit packs are glorified stuff bags with flimsy shoulder straps. However, our IN & OUT is a fully engineered yet featherweight solution. Designed to stuff into its front, mesh pocket – packing the size of a small water bottle – it fits perfectly in your backpacking pack, everyday carry pack, purse, and luggage. It features contoured shoulder straps and a sternum strap. Built from 100D CORDURA® mini-rip for high abrasion and tear resistance, this full-featured, packable daypack will get you IN & OUT, whatever your mission might be.
