What is the conversation mainly about?

W: Hi Tarry, I will be going sports camping next weekend!
M: Really? I love camping. I go all the time with Alex and Jim.
W: Oh, good, then you can tell me about it.
M: No problem, uh, Laura, what do you want to know?
W: What should I bring?
M: That’s a big question. Besides badminton and football, you should bring tents, of course. Especially the one made of canvas, because these fabrics supply strength, fireproofing, waterproofing and adequate ventilation (通风) .
W: What else should I bring?
M: Well, you should also bring sleeping bags. They are easier to carry than blankets and provides a more efficient insulation (隔热) to keep campers warm.
W: Thank you. Then what about clothes?
M: Oh, you should bring clothes that protect against wind, rain, sun, cold and insects like wool shirts. One more thing, you should definitely wear hiking boots because the land will be rough. And inside the boots wear two pairs of socks. It will provide warmth.
W: OK, sorry to ask you so much but one more question, what about other camp supplies?
M: That’s a necessity. You should bring tools such as hammers, flashlights, hunting knife, rope, towels, matches and batteries. Oh, and maps, it’s a must.
W: Thank you for telling me so much. I think I am ready to go camping.
M: Hope you have a wonderful time.
W: Thank you. I sure will follow your tips.
