There are ways that you can make your trip not only enjoyable but comfortable without spending much money. It is true that people who have the true spirit of backpacking do not make lack of comfort a big issue but when there are ways through which they can increase their level of comfort then why not look into and adopt those ways? If you go backpacking with material things that might provide you with physical comfort, you would notice that you would enjoy the trip more, both emotionally and mentally.
Carry a Backpacking Pillow
Some people at the idea of taking pillows on a backpacking trip but they are the same people who have neck cramps and shoulder pain due to sleeping with their backpacks under their heads so it is safe to say that you should definitely look into backpacking pillows. The best advice that we can give you about backpacking is that you take a backpacking pillow with you and we would recommend the self inflating ones which you can read about on this site. While purchasing a pillow, remember to choose one that comes under your budget and fits your taste.
People often fall sick during their backpacking trips because they drink unhealthy water but you can avoid that by purchasing a good camping water filter. It would provide you with clean water and most filters are portable so you can carry it everywhere.
If you do not wish to carry around a camping bed with you, it is completely understandable but did you know that you can sleep in a hammock on your trip? All you would need is a good quality hammock and two pole like structures to support it and you would have great sleep.
