Between the sun, insects—mosquitoes—and underbrush during jungle trek excursions, you’ll want to ensure your body is physically covered for most of your trip. Yes, it’s hot and humid, so full gear may not appeal to you, but it’s better than the alternative of sunburn, bug bites, and scratches. If you buy a lightweight, long sleeve top (a bonus if it has UPF and temperature control), you may find you’re actually cooler than if you were in short sleeves.

It may be tempting to pack thin rain pants, tracksuit bottoms, or even leggings for women, but the jungle is thick, and most underbrush can prod through those thin materials—not to mention mosquitoes can bite through leggings. Find a thicker style like cargo or hiking pants and invest in a few pairs for your trip; you’ll want to pack multiple pairs of trousers to rotate out after working up a sweat during jungle treks.

For style and sun protection, pack a bandana or buff. Tying a bandana around your neck or slipping on a buff over your ears and under your hat protects the oft-neglected areas for applying sunscreen and bug spray. It’s all about full coverage in the Amazon.

A classic pair of sunglasses with polarized lenses will save your eyes from the glare of the Amazon, where the reflection is even harsh during rain storms. You’ll discover you need these for the majority of your day, so attach them to a croakie or strap so as not to lose them as you slide them on and off—and in case you should lose them, it’s always ideal to have a backup pair so be sure to pack an extra.

You can’t go wrong if you decide to slip on rain boots or lace-up hiking boots. But, do pay attention to the height and cut of the boot; you want to be comfortable in a fit that cuts above the ankle, at the very least. If the tall boot isn’t your look, the cruise offers garters to wrap around the shins and protect from underbrush or chiggers (oh, the joys of the jungle!).

Yes, all of these items are essentials, but a rain jacket is the ultimate necessity for a trip into the rainforest. Since you’re going to wear it daily—depending on the time of year you visit it may rain all day or intermittently but guides advise you to always carry your jacket with you—so you want something lightweight, fast-drying, and, of course, somewhat stylish. Prepare to hang up your jacket, in your cabin or above deck, after every outing for it to dry before the next activity.
