When shopping for hiking tents, you will want to look for one that is lightweight or ultralight and easy to assemble. Being lightweight just makes sense, as you do not want to add any extra weight to the load you will be carrying on your back; and having something that is quick to set up will make your trip more enjoyable - especially if you may be setting up camp late at night or in not-so-pleasant weather conditions.
Also, it will have to be warm enough to protect you from the elements should anything unexpected happen (like if you get lost....you don't want to freeze to death while waiting for help!). So just make sure that if you are going to be using it in colder conditions, it is made for it.
Look for something that is either waterproof or comes with a protective cover that is.
For this type of activity, you will usually get either a 1 or 2 man camping tent; however, you can find larger ones if you are planning to camp with more people, such as if you are going on a trip with your family.
