What do you need to pack for a three-season backpacking trip? While the specific items depend in part on factors like the precise time of year, your companions and backpacking style, and the trip’s length and weather forecast, this story provides a core checklist of essential gear to help you organize and efficiently pack—and avoid overpacking—for virtually any backpacking trip.
I use the checklist below for just about every three-season backpacking trip I take in the U.S. and around the world. I’ve developed it over more than three decades of multi-day backcountry trips and more than a quarter-century of writing about backpacking trips and testing and reviewing backpacking gear and apparel, including the 10 years I spent as a lead gear reviewer and Northwest Editor of Backpacker magazine and even longer running this blog.
The list below is preceded by some insights on how I make gear choices. The links in this story and checklist will take you to menus of product reviews; photos link to stories about those trips.
See my Custom Trip Planning page to learn how I can help you plan your next trip—including answering all of your questions. Please share your thoughts on my list and tips and offer your own suggestions in the comments section at the bottom of this story. I try to respond to all comments.

How to Decide What Gear to Pack
I pare my checklist for any specific trip down to just essentials, which vary from trip to trip. As examples, I will carry a warmer down jacket on some, a lighter one on others, or a synthetic puffy jacket if I expect wet weather. On most trips, it’s just one puffy jacket; I don’t need an extra fleece or a vest on most three-season trips because, if it’s cool in the morning, I’ll hike in my long-sleeve jersey over my T-shirt, with my shell jacket on to trap a little extra warmth if needed, and then typically for no more than an hour or two until it’s warm enough to shed one or two layers.
I bring a tent when I expect bugs or significant rainfall, but a tarp for late summer or early fall if I only need protection from possible rain—for instance, after Labor Day in Yosemite or Sequoia national parks and any of the numerous wilderness areas in the High Sierra, like the John Muir Wilderness, when you don’t have to worry about mosquitoes and rain is not common.
For base layers, I’ll bring one T-shirt and one midweight long-sleeve jersey, which I’ll usually only need hiking on cool mornings, so I can keep it dry for sleeping in when needed. I’ll bring two pairs of socks for trips of up to five days and at most three pairs of socks for trips of more than five days—and if I expect very dry conditions, two pairs may suffice even on long trips.

I allow myself a few luxuries on many backpacking trips, including a comfortable, lightweight or ultralight air mattress augmented by a short, folding foam sleeping pad that I use for lying around camp, as a stretching/yoga mat (which helps me feel better), and under my air mat when sleeping; plus an inflatable pillow and often an ultralight camp chair.
Incidental items like permit, passport, bug nets, gaiters, type of hat (it’s usually one wool hat and one ball cap or wide-brim sun hat), and pack cover also depend on the trip’s circumstances. I virtually always carry one DSLR body and two lenses. I’ll often have just one eating utensil and one mug/bowl that pulls double duty, and one pot, and I may just eat out of the pot.
