Temperature is the most important consideration when deciding what to wear. Not dressing appropriately can have devastating consequences, both in high and low temps.
Even in summer, it’s wise to pack some lightweight pants and a breathable, long-sleeve shirt. If the bugs are out for blood, you’ll be thankful to have those extra layers. Many long-sleeve garments also offer UPF sun protection.
PRO TIP: Never leave home without a mosquito head net. This cheap and extremely unobtrusive piece of gear is simply a life-saver.
