You’re looking for a new hiking backpack, and the wall of options is overwhelming. You’ve heard of Osprey, seen Gregory, and maybe a friend mentioned an "ultralight" brand. Which one is actually the most popular, and does "popular" even mean "best"?

The most popular brands are Osprey¹ and Gregory, which dominate mainstream sales and retailer recommendations due to their advanced fit systems and lifetime warranties. For ultralight hiking, "cottage" brands like Hyperlite Mountain Gear, Zpacks, and ULA Equipment are the most popular, as shown in long-distance trail surveys. For budget-conscious beginners, REI Co-op and Kelty are top choices, while Deuter is popular for its superior back ventilation.

This guide provides a complete breakdown of which brands are popular, why they’re popular, and—most importantly—which one is right for you.

How Did We Define "Popularity" Beyond Just Sales Figures?

"Popularity" is a tricky metric. The most-sold brand isn’t always the best, and the most-hyped brand isn’t always the most durable.

To give you a complete picture, we defined "popularity" by synthesizing data from three distinct metrics: mainstream retail sales, pro-level long-distance trail surveys, and online search and community buzz.

What Three Data Sources Did We Use?

This blended methodology provides a complete picture of the backpack landscape:

• Mainstream Retail Sales: We analyzed best-seller lists from major retailers like REI and Backcountry.com. This reflects the "mass market" and what most weekend hikers buy.
• Long-Distance Hiker Data: We analyzed TheTrek’s 2023 Appalachian Trail Thru-Hiker Survey². This data shows what brands actually survive thousands of miles of abuse (This reflects the "pro" market).
• Search & Community Volume": Google Trends data³ and mentions within large online hiking communities (This reflects brand "buzz" and current trends).

What’s the Difference Between Retail vs. Trail Popularity?

As one outdoor gear buyer notes, "A brand’s popularity on a retail shelf often points to a strong warranty and good retailer margins. But popularity on a trail like the AT points to pure, field-tested performance and low weight."

What Defines a Top Hiking Backpack Brand?

Before we look at which brands are popular, it’s crucial to understand why they’re popular. A brand doesn’t reach the top of the list by chance; it’s a result of consistently delivering on a few key promises that are non-negotiable for serious hikers.

A top hiking brand is defined by its mastery of four pillars: 1) Advanced Fit & Comfort, 2) Purpose-Driven Durability, 3) A "No-Questions-Asked" Warranty, and 4) A Smart Weight-to-Feature Ratio.

What Are the Four Pillars of a Top-Tier Brand?

The best brands don’t just excel in one of these areas; they find a way to balance all four to create a pack that feels reliable, comfortable, and worth the investment.

This table summarizes what to look for in each category:

The "Big Two" Titans: Why Do Osprey and Gregory Dominate 80% of the Trail?

When you walk into any gear shop, you’ll immediately face the "Big Two": Osprey and Gregory. These brands are the titans of the mainstream hiking world for good reason.

These brands win on two fronts: iron-clad lifetime warranties and industry-leading suspension systems. Osprey’s "All Mighty Guarantee" (a lifetime repair/replacement warranty) drives incredible customer loyalty, while Gregory’s "Response A3" harness is an industry benchmark for how a pack can pivot with your hips for long-distance comfort.

How Do Osprey and Gregory Compare Head-to-Head?

While both are top-tier, they have different core philosophies. Osprey is often described as feeling lighter and more ventilated, while Gregory is known for its plush, load-hugging comfort.

The Ultralight Vanguard: Who Are the "Cottage" Brands That Own the Thru-Hike?

You might be surprised to learn that the "Big Two" are not the most popular brands on long-distance trails like the Appalachian Trail (AT) or Pacific Crest Trail (PCT).

According to TheTrek’s 2023 Appalachian Trail Hiker Survey, the top five most popular pack brands were all "cottage" or ultralight-focused companies. These small-batch brands are built by hikers, for hikers, and prioritize low weight above all else.

What Are the Most Popular Ultralight Brands?

The 2023 survey data shows a clear dominance by these specialized brands:

• Hyperlite Mountain Gear (20.5%)
• ULA Equipment (16.9%)
• Zpacks (16.1%)
• Gossamer Gear
• Waymark

Why Are These Brands So Popular with Pros?

These "cottage" brands are popular because they ditch features like extra zippers, heavy frames, and excess pockets to achieve a sub-2lb base weight.

• They use advanced materials like Dyneema Composite Fabric (DCF), which is 15x stronger than steel by weight and fully waterproof, eliminating the need for a pack cover.

Which Popular Brand Is Right for Your Hiking "Tribe"?

The "best" brand is a myth. The "right" brand depends entirely on your specific hiking style, budget, and goals.

We’ve grouped the 20 most popular and reputable brands into the five main "tribes" they serve. This helps you self-select the right brand for your needs, whether you’re a weekend warrior or a minimalist thru-hiker.

Expert Advice: Stop Shopping by Brand and Start Shopping by Torso Length

This is the single most important section of this article.

The #1 mistake new hikers make is buying a popular brand that doesn’t fit them. A $400 pack will cause you pain if it doesn’t match your body. The most critical measurement for pack comfort is your torso length, and it has nothing to do with your height.

A 6’3" person and a 5’5" person can have the exact same torso length. Before you look at a single brand, get measured.

How to Measure Your Torso Length⁵ (The REI Method):

1. Get a Friend and a Soft Tape Measure.

2. Find the C7 Vertebra:
   Tilt your head forward. The C7 is the largest, most prominent bone at the base of your neck. This is your starting point.

3. Find the Iliac Crest:
   Place your hands on your hips, thumbs pointing backward. The "shelf" of your hip bone is the iliac crest.

4. Measure:
   Have your friend run the tape measure from your C7 vertebra down your spine to the imaginary line connecting your thumbs on your iliac crest.

That number (e.g., "19 inches") is your torso length. You are now empowered to buy the right size pack (S, M, L), which is far more important than the brand name.

Which Brands Lead in Innovation and Materials?

Innovation is happening in two different arenas: mainstream brands are innovating for "comfort," while ultralight brands⁶ are innovating for "materials."

Osprey and Gregory lead in complex suspension systems that enhance comfort for the masses, while cottage brands like Hyperlite Mountain Gear lead in using advanced, lightweight fabrics like Dyneema (DCF) and UltraPE.

Who Is Innovating in Mainstream Comfort?

For out-of-the-box comfort and ventilation, the leaders are:

• Osprey: With its Anti-Gravity (AG) suspended mesh back panel that makes the pack feel like it’s floating.
• Gregory: With the Response A3 dynamic hip belt that pivots with your body’s natural hiking motion.

Who Is Innovating in Ultralight Materials?

The cottage brands are the true leaders here, popularizing fabrics that are stronger and lighter than traditional nylon:

• Hyperlite Mountain Gear: Popularized Dyneema Composite Fabric (DCF), an absurdly light, strong, and waterproof laminate.
• ULA & Zpacks: Driving the adoption of UltraPE (Ultra), which offers even higher abrasion resistance than DCF at a similar weight.

How Do Brand Design Philosophies Differ?

To find the right brand, it helps to understand the "why" behind their design. Every brand is trying to solve a different problem for the hiker.

You can group most major brands into three main design philosophies: "Kitchen Sink" (feature-rich), "Load-Hauling Comfort" (suspension-first), or "Subtractive" (ultralight minimalism).

What Are the Three Main Design Philosophies?

• "Kitchen Sink" (Feature-Rich):
  • Brands: Osprey and Thule.
  • Philosophy: These brands believe a good pack should have a solution for everything: a pocket for your sleeping bag, straps for your poles, an integrated rain cover, and multiple access zippers. They prioritize organization and convenience.
• "Load-Hauling Comfort" (Suspension-First):
  • Brands: Gregory and Mystery Ranch.
  • Philosophy: These brands build their packs from the harness out. Their goal is to make 50 pounds feel like 30, even if the suspension system⁴ adds a little weight.
• "Subtractive" (Ultralight Minimalism):
  • Brands: Hyperlite, Zpacks, and Gossamer Gear.
  • Philosophy: These brands start with a simple bag and ask, "What can we remove?" They replace heavy features with lightweight materials, believing the most comfortable pack is the lightest one.

Conclusion: From Popular Brands to Your Perfect Pack

Ultimately, the ‘most popular’ brand isn’t as important as the right brand for you. The key is to find a pack that matches your hiking ‘tribe,’ balances the right features with the right weight, and—above all—fits your specific torso length. The principles that make brands like Osprey or Hyperlite great are universal: a commitment to fit, function, and purpose-driven design.

At Osgoodway, we transform those same principles into real products — manufacturing custom hiking backpacks that balance performance, comfort, and design.

Frequently Asked Questions About Hiking Backpacks

What is the single most popular hiking backpack brand?

Osprey. It consistently leads in mainstream retail sales, search interest, and general trail visibility. Its combination of a lifetime warranty, strong feature set, and comfortable "Anti-Gravity" suspension makes it the default, top-of-mind brand for most hikers.

What is the main difference between Osprey and Gregory?

The primary difference is their fit philosophy. Osprey packs are often described as feeling lighter and more ventilated, as if they’re "floating" off your back (like the Atmos AG). Gregory packs are known for their robust suspension that "hugs" your body and excels at comfortably transferring heavy loads to your hips (like the Baltoro).

What hiking backpack brands have a lifetime warranty?

The "Big Three" for warranties are Osprey (All Mighty Guarantee), Gregory (Lifetime Guarantee), and Deuter (Repair Service for the life of the product). REI Co-op also has an excellent 1-year satisfaction guarantee. Note: Many "cottage" ultralight brands do not offer lifetime warranties, as their lightweight materials are not designed for decades of abuse.

Are expensive hiking brands like Arc’teryx worth it?

It depends. Brands like Arc’teryx and Black Diamond are popular in the climbing and mountaineering world. You are paying a premium for technical, lightweight, and weatherproof materials designed for extreme alpine conditions. For most trail hikers, the features (like an ice-axe loop or a "crampon pocket") are unnecessary, and a brand like Osprey offers better "hiking-specific" comfort for the money.

What’s a good, popular brand for a beginner?

The best popular brands for beginners are REI Co-op and Kelty. They offer the best balance of price, durability, and essential features without the high cost of premium-brand suspension systems. The REI Co-op "Trail" series and the Kelty "Asher" series are consistent "best value" winners.
