I'm trying to decide what's better for a 4-day backpack hunt, a tent (5 lbs.) or lightweight shelter (2 lbs.). The tent is heavier and bigger but provides a lot of ventilation for those warm August nights and has mesh to keep out the bugs. The shelter is a lot smaller and lighter but looks like it will block the breeze and provide no refuge from mosquitoes. Any first hand experience that would help me figure this out?
