How I picked these

I’ve been backpacking for 16 years and hiking for 20, and I’ve owned and used a lot of gear in that time. I know what works on overnight trips and what doesn’t: gear that holds up, packs down, and earns its place on your back.

I compared these backpacking backpacks on carrying comfort, suspension, ventilation, adjustability, organization and durability. Picks are based on that experience, manufacturer specifications and long-term owner feedback.

1. Osprey Atmos AG 65: best overall

The Atmos AG 65 is famous for its Anti-Gravity suspension, a continuous mesh panel that wraps your back and hips. It spreads weight evenly and keeps air moving across your back on hot climbs.

With adjustable torso length and plenty of pockets, it’s easy to fit and organize. Osprey’s All Mighty Guarantee is a bonus.

Where it falls short: it’s heavier than minimalist packs.

2. Gregory Baltoro 65: best for heavy loads

Gregory’s Baltoro is built to carry heavy loads comfortably, with a supportive frame, a pivoting hip belt and smart organization. It’s a great pack for winter trips, long hauls and carrying group gear.

Where it falls short: it’s heavy and expensive.

3. Osprey Exos 58: best lightweight

The Exos 58 trims weight while keeping a real frame and ventilated back. It’s a great step toward lighter backpacking without going fully minimalist.

Where it falls short: it’s not designed for very heavy loads.

4. Deuter Aircontact Lite (Women’s): best for women

Deuter’s women’s Aircontact Lite has shoulder straps and a hip belt shaped for women, with an adjustable back length for a dialed fit.

Where it falls short: it’s heavier than lightweight packs.

5. TETON Sports Mountain Ultra: best budget

TETON Sports packs are popular first backpacks thanks to their low price, adjustable fit and included rain cover.

Where it falls short: the suspension isn’t as comfortable as Osprey’s or Gregory’s on long days.

How to size a backpacking pack

• Measure your torso: from the bony bump at the base of your neck (C7) to the top of your hip bones.
• Check hip belt size: it should sit on your hip bones, not your waist.
• Load it before you buy: try it with 20-30 lbs inside.
• Adjust in order: hip belt, shoulder straps, load lifters, then sternum strap.

What capacity do you need?

• 30-50 liters: overnight trips or ultralight multi-day trips.
• 50-65 liters: most 2-5 day trips.
• 65+ liters: winter trips, long trips without resupply, or carrying gear for kids.

The big three: shelter, pack and sleep system

Your tent, backpack and sleeping bag and pad are usually the heaviest items you carry, so they’re the best place to save weight. Cutting a few pounds across the big three makes more difference than shaving ounces anywhere else. Start with a shelter and sleep system that match your climate, then choose a pack sized for the gear you actually carry.

How to pack a backpacking pack

• Bottom: sleeping bag and camp clothes you won’t need until night.
• Middle, close to your back: the heaviest items, like food, water and cook kit.
• Top: rain jacket, warm layer, first aid and water filter.
• Pockets: snacks, map, sunscreen and headlamp.
• Use a pack liner to keep everything dry.

Gear shakedown before your trip

• Set up your tent, inflate your pad and test your stove at home.
• Weigh your loaded pack and cut anything you didn’t use on your last trip.
• Check the forecast and pack layers for the coldest likely night.
• Pack the ten essentials: navigation, light, sun protection, first aid, knife, fire, shelter, extra food, extra water and extra clothes.
• Tell someone your route and expected return time.

Leave No Trace at camp

• Camp on durable surfaces like established sites, rock or gravel, at least 200 feet from lakes and streams.
• Pack out all trash, including food scraps.
• Use established fire rings, or skip the fire and use a stove.
• Store food properly to protect wildlife.
• Leave what you find, and respect other visitors.
