Besides the amount of persons we have to consider that the luggage, shoes, and other things will take up space. If you will have more luggage and you are 3 people, you can take a tent for 4 people.

You can use outdoor tent at any outdoor activity from festival, a stay in camp or camping in the wild. These tents are smaller, lighter and take less space.

Tents in this range can haldle normal rain, however it also depends on other circumstances such as wind, place where you are sleeping, and how well do you build the tent. The floor should have higher water resistance so the water cannot leak from bellow.

Are you going for a longer hike or cycling trip? Then it is best to pack up the lightest tent possible. The weight then depends on its size and materials used. The low weight should not be at the cost of quality.
