Some manufacturers organize their kits by the number in a party and the length of the trek. The Weekender is advertised for a group up to six people and trip duration of seven days. This has material for a large wound, like you asked, including material to clean and close it: povidone iodine, 20cc irrigation syringe and wound closure strips.

Some of the features I like about this one is it has 3" x 4" non adherent dressing as apposed to 2" x 3", EMT Shears and 1" tape as 1" tape is easier to work with than ½ tape.

I have no affiliation. I have bought a number of their products over the years.
