You will find that having the right towel with you when you go travelling is extremely important. Travel towels have been designed for a specific purpose so they are great, or rather, an essential accessory. Yes they are more expensive than normal towels but there are very good reasons for that.
I had seen a travel towel that my older brother had when he went off on his travels. I didn't think much of it. I only really obsverved how difficult it must be to dry your body as it was so small and well... uncomfortable. I couldn't understand why he didn't just take a beach towel with him.
Even when I went travelling for the first time in my life I didn't appreciate the importance of the travel towel. I had the bright idea of taking my beach towel... that wasn't the case. I knew that a lot of our time would be spent swimming in the sea and have a laugh on the beach. It didn't work out like that. It wouldn't dry between trips and started to smell. It also took up valuable space and was heavy.
The advantages of travel towels are the exact opposite of everything that was wrong with my large beach towel. It is because of the absorbent material that you dry quickly plus then the towel doesn't remain wet. You will find this crucial when you are moving from place to place as there won't be much time for your towel to dry out. If your towel doesn't dry properly then it will begin to smell. This will make the other items in you bag smell a lot as well.
Travel towels don't take up as much room which is a real benefit. While you can get different sizes of the towels, none will take up a lot of room in your bag. I found this because I wanted to by a lot of mementos along the way.
