One-of-a-Kind Adventure: Cotopaxi Allpa 35L Del Día – Bold Style Meets Rugged Travel Utility

Introduction: The Most Unique Backpack You’ll Ever Own

Walk through any airport, and you’ll see a sea of black, gray, and navy backpacks. They blend together into an indistinguishable mass of corporate-approved neutrality. Then, occasionally, you’ll spot something different—a burst of color, a patchwork of vibrant hues, a bag that announces its owner is anything but ordinary.

That’s the Cotopaxi Allpa 35L Del Día. Every bag in the Del Día (Spanish for “of the day”) series is unique, assembled from remnant fabrics in vibrant, randomly combined colors. No two bags look exactly alike. This commitment to individuality extends beyond aesthetics—Cotopaxi is a certified B Corporation that donates a portion of every sale to fighting poverty.

But is the Allpa 35L Del Día more than just a pretty face? After testing this bag on a two-week trip through South America—flights, buses, cobblestone streets, and all—I discovered a travel backpack that successfully combines bold style with genuine functionality.

In this comprehensive review, we’ll explore whether the Allpa 35L Del Día’s unique aesthetic is backed by real-world performance.

Design Philosophy: Individuality with Purpose

The Cotopaxi Allpa 35L Del Día is built on two principles: sustainability and individuality. The bag is made entirely from remnant fabrics—leftover materials from larger production runs that would otherwise go to waste. By using these remnants, Cotopaxi creates a product with a lower environmental footprint than traditional backpacks.

The “Del Día” designation means your bag is assembled from whatever remnants are available, in whatever colors, combined by skilled artisans. The result is a bag that is truly one-of-a-kind. You won’t see another backpack exactly like yours—a refreshing change in a world of mass-produced uniformity.

Beyond sustainability, the Allpa 35L is designed as a travel backpack first and foremost. It opens like a suitcase (clamshell) for easy packing, includes a robust harness system for comfort, and is sized for carry-on compliance. The colorful exterior doesn’t compromise functionality—it’s built on a solid foundation of thoughtful travel design.

The bag features a hip belt with pockets, multiple handles for different carrying positions, and compression straps to reduce bulk. Cotopaxi clearly understands what travelers need, even as they push boundaries on aesthetics.

Cotopaxi is a certified B Corporation and a member of 1% for the Planet, donating 1% of all revenue to nonprofit organizations fighting poverty. When you buy an Allpa Del Día, you’re not just buying a backpack—you’re supporting a mission.

Material Science: Remnants and Responsibility

The Cotopaxi Allpa 35L Del Día uses a 100% remnant fabric construction. The specific materials vary depending on what leftovers were available, but typically include:

• Exterior: Polyester or nylon in various deniers (most commonly 450D-600D)
• Lining: 200D polyester (recycled where possible)
• Back panel: Mesh-covered foam padding
• Hardware: YKK zippers and Duraflex buckles

Because the bag uses remnant fabrics, the material specifications vary by bag. Some Allpas use more durable 600D polyester; others use lighter 450D nylon. In practice, all the materials are appropriate for travel use—I found no durability issues with any of the remnant combinations.

The exterior fabrics have a water-resistant coating. In testing, the bag handled 20 minutes of moderate rain with no interior moisture. For heavier downpours, Cotopaxi sells an optional rain cover (sold separately). Given the bag’s travel focus and vibrant colors that might show water spots, including a rain cover would be appreciated.

The YKK zippers are robust and lockable—the main compartment zippers can be secured with a small travel lock. The zipper pulls are large and easy to grab, even with cold or gloved hands.

The fabric’s color is solution-dyed, meaning the color is part of the fiber rather than printed on top. This prevents fading and ensures the bright colors stay vibrant for years.

Storage Architecture: Travel-Optimized Design

The Cotopaxi Allpa 35L Del Día is built around a suitcase-style clamshell opening—the best design for travel backpacks. You can lay the bag flat, open it completely, and see everything inside.

Main Compartment: Divided and Organized

The main compartment is divided into two sections by a zippered mesh panel. This internal division is brilliant:

• One side for clothing, shoes, and soft items
• The other side for gear, tech, and structured items

The mesh panel keeps everything visible—no forgetting what you packed on the other side. The panel is zippered, so you can separate sides completely or leave it open for larger items.

The main compartment also includes:

• Compression straps to secure your load and reduce bulk
• A zippered mesh pocket on the lid for small items
• A large open space for flexible packing

Sample loadout from testing (2-week trip):

• 6 shirts
• 3 pairs of pants/shorts
• 8 pairs of socks and underwear
• 1 lightweight jacket
• 1 pair of sandals (in addition to worn shoes)
• Dopp kit
• Tech pouch (charger, cables, power bank, adapters)
• 15-inch laptop
• Tablet
• Book
• Water bottle
• Travel documents

The 35L capacity held everything comfortably, with room for souvenirs. For reference, 35L is the sweet spot for carry-on travel—large enough for extended trips but small enough to fit in overhead bins on almost all airlines.

Laptop and Tablet Compartment: Full Protection

The rear of the bag houses a dedicated laptop compartment accessible via a separate zipper. The compartment includes:

• A padded laptop sleeve (fits up to 15.6 inches)
• A tablet sleeve
• A zippered mesh pocket for documents or small accessories

The laptop sleeve is suspended with a false bottom—your laptop never touches the ground, even when you drop the bag. The padding is adequate for travel use, though not as thick as some dedicated laptop backpacks.

The laptop compartment is positioned against your back when wearing the bag, which improves weight distribution and security.

Front Pocket: Quick-Access Essentials

A zippered front pocket sits on the top front of the bag. Inside, you’ll find:

• A key clip
• A small zippered mesh pocket
• Open space for travel documents, phone, wallet, boarding pass

The front pocket is well-sized for daily essentials and easily accessible even when the main compartment is fully packed.

Side Handle and Water Bottle Pocket

The Allpa 35L features a single external water bottle pocket on one side. This is a notable design choice—most travel backpacks have two pockets or none at all.

The pocket is stretchy and deep, fitting bottles up to 32 oz securely. During testing, a Nalgene 32 oz bottle stayed in place during walking and even running for buses.

The other side features a carry handle (more on handles below) and a small zippered pocket sized for a passport or phone.

Carry Handles: Everywhere You Need Them

The Allpa 35L has carry handles on all four sides—top, bottom, left, and right. This may seem excessive, but in practice, it’s incredibly useful:

• Top handle: Standard carry and overhead bin placement
• Bottom handle: Lifting from floor, pulling out from under seats
• Side handles: Carrying like a briefcase, passing through crowds

The handles are padded and comfortable to grip, even with a fully loaded bag.
