Proper dress code depends on what you will be doing within the office. Generally speaking, much of the work you will be doing around the office is physical in nature, so casual and comfortable clothing is appropriate. On trail, you will be given a Wilderness Inquiry staff shirt and hat which you should wear along with a nice pair of outdoor pants or shorts (no jeans). You should have a business casual outfit on hand in case you are ever asked to help with a presentation or outreach event.
