He has a nice kit. I have done "trekking" and walk-in camps with similar gear. The only thing I do differently is I will add an additional blanket or two because I am in higher elevations and the temps often get below freezing at night. I also wrap my bedroll in an oilcloth which can be handy should there be rain or morning dew.
It can be daunting sleeping out with only a couple blankets the first time. But the more you do it, the easier it gets. Its pretty amazing what a person can adapt to. Your confidence level will increase and you will have many stories to tell of warm fires, cold nights and nasty weather. I encourage all who have thought about it to give it a try at least a few times. If nothing else it will make you appreciate what you have.
