you'll be surprised how little space you need if you pack clothes and sleeping bag down in a compression sack and don't take large hard items.
Yup!
The green compression sack is a 25 degree synthetic bag (1.5lbs.), the blue compression sack is a Sierra Design Lightning 2-person tent and rainfly(4lbs), and orange bag is full length Themarest Prolite 4. The water bottle is for scale.

Gray bags hold sil-nylon tent ground cloth and a stuffable down pillow. Everthing fits in Medium Ortlieb Rack Pack with room for my running shoes.

It is roomy for it's weight.

and versatile.
