This is going to be pretty variable based how insulating the cover is, how hot it is outside, etc.

If you don't mind the expense, do a few practice steaks at home and test and see how long they stay cold. Leave them in the sleeve, in your pack, outside, to simulate the conditions you'll be putting it under.

As far as ways to keep it cold longer (that are also lightweight), you could get some lightweight ice packs (reviews on these report 10 hours of cooling in a lunchbox), wrapping the sleeve in a highly insulating material like Reflectix or layers of foil, or trying to insulate your bag as well as the sleeve.

All together, I bet it's possible, but the only way to know it's safe is to try it before you need it :\

Edit: Removed note about the thickness of the steak - that's not really a variable here, as you should be concerned as soon as even the exterior starts hitting 40°F

Those are the ones I've bought last and are the best I've had personally. I've seen them freeze things that weren't frozen.
