Hey fellow adventurers, I hope all of you have been doing great! I believe I have decided to go with an ULA Circuit, I've done my research on it and really like it. In general, what down sleeping bag would you select to go with it? I guess my main concern is making sure the sleeping bag will actually fit inside the pack so that's why I ask. Any ideas or suggestions of sleeping bags will be greatly appreciated. Thanks for everything and happy trails!!
