It depends. If you're expecting heavy winds, you will want to purchase a heavier tent for durability and stability purposes. For those who simply need to make sure their tent stays up against moderate winds, your standard "instant" tents will be fine. Insulation is often compromised with these style tents, as well as having low ventilation which can cause heat retention and internal moisture buildup - both of which are caused by zipper holes or modified windows that have reduced resistance for airflow through the tent body itself. The lower cost factor coupled with the option to use one's own sleeping bag or air mattress ultimately compensates for this lack of features with many people still finding instant tents an affordable alternative shelter solution when setting up camp in mild weather conditions.
