The 48 doesn't come with a sleeping bag compartment. However, I'm not sure about other larger model exos packs. If you take the compartment off the top of the bag you can save some ounces.

For now I will have to have the stuff sack on my sleeping bag due to very wet conditions in Maine. It is cuben finer and weights little to nothing. I have another summer bag (kelty cosmic down 40 degree) I plan to sub out once the weather gets warmer in the North East.

The Platy 1L has a plastic clip on the side that makes it have a little more weight. Im probably going to cut it off, just wasn't paying attention at the store when it was purchased.

I am probably going to add a few ounces because I will need a better recharge system to keep up with my elctronics while on the trail. Im looking into an Anker 10000mHA.

Thanks for the feedback!
