The best canopy tents are portable, easily collapsible and provide all -day, multi-weather protections, some even protect you from insects. One thing to keep in mind regarding camping canopy tents is that they are not meant for extended use as they are vulnerable to UV damage. 

You should also never pack away a wet or damp tent as that causes mildew.
