First Impressions – Sleek Design Meets Practicality

The 35L Medium Travel Backpack by Peak Design immediately catches the eye with its minimalist yet sophisticated aesthetic. Crafted with a sleek, modern silhouette, it’s the kind of bag that looks equally at home in an airport lounge as it does on a rugged trail. The backpack is constructed from 100% recycled 400D nylon canvas, giving it a premium feel while staying true to eco-conscious values. The material is smooth but tough, with a weather-resistant coating that shrugs off light rain and dust. The Coyote color option, in particular, adds a touch of rugged charm, making it a standout choice for those who want to blend style with adventure.

At 35 liters, this backpack strikes a sweet spot for travelers who need enough space for a multi-day trip but don’t want the bulk of a larger pack. It’s carry-on compliant for most airlines, which is a huge plus for those who prefer to skip checked luggage. The dimensions—22” x 14” x 9” when fully packed—make it compact enough to slide under an airplane seat or into an overhead bin with ease. Yet, what sets this bag apart is its ability to expand or compress depending on your needs, offering flexibility that’s rare in travel backpacks.

The first thing I noticed when unboxing the bag was its attention to detail. The magnetic flap closure on the top feels satisfyingly secure, and the oversized #10 weatherproof zippers glide smoothly without snagging. The backpack also features padded shoulder straps and a removable waist belt, both of which can be tucked away when not in use. This thoughtful design ensures the bag doesn’t scream “tourist” when you’re navigating a bustling city. It’s clear that Peak Design has poured years of expertise into creating a bag that’s both functional and stylish.

Packing and Organization – A Place for Everything

One of the standout features of the 35L Medium Travel Backpack is its organization system. For travelers who value efficiency, this bag delivers in spades. The main compartment opens fully like a suitcase, providing easy access to your gear. This clamshell-style opening is a game-changer for packing and unpacking, especially when you’re living out of the bag for days or weeks. Unlike traditional top-loading backpacks, this design lets you see everything at a glance, making it easy to find that one elusive item buried at the bottom.

Inside, the backpack offers three main compartments, supplemented by two internal mesh pockets and four external pockets. The internal pockets are perfect for smaller items like toiletries, cables, or travel documents, while the external pockets are ideal for quick-access essentials like a water bottle, passport, or snacks. I particularly appreciated the dedicated ID pocket, which is discreetly placed for easy access during airport check-ins. The backpack also integrates seamlessly with Peak Design’s packing cubes and accessory pouches, allowing you to customize the interior layout to suit your needs.

During a recent weekend trip to the Pacific Northwest, I packed the 35L backpack with three days’ worth of clothing, a 15-inch laptop, a camera, and various accessories. The bag swallowed everything with room to spare, thanks to its expandable design. When fully expanded, it can stretch to nearly 45 liters, though I found the 35L capacity sufficient for most short trips. The compression straps on the sides helped keep the load snug and balanced, even when I didn’t fill the bag to capacity. For photographers or tech enthusiasts, the backpack’s compatibility with Peak Design’s camera cubes is a major selling point, offering padded protection for expensive gear.

The only minor gripe I have is that the internal mesh pockets could be slightly larger for bulkier items like a power bank or travel adapter. However, this is a small trade-off for the overall organizational prowess of the bag. Whether you’re a meticulous packer or someone who tosses everything in at the last minute, this backpack makes it easy to stay organized without feeling overwhelmed.

Comfort and Wearability – Built for Long Journeys

Comfort is a critical factor for any travel backpack, especially when you’re carrying it for hours through airports, train stations, or city streets. The 35L Medium Travel Backpack excels in this department, thanks to its ergonomic design and thoughtful weight distribution. The padded shoulder straps are wide and contoured, reducing pressure on your shoulders even when the bag is fully loaded. The removable waist belt is a nice touch for longer treks, as it transfers some of the weight to your hips, making heavy loads feel more manageable.

During a 12-hour travel day that involved a flight, a long layover, and a train ride, the backpack remained comfortable throughout. The back panel is well-padded and breathable, preventing that dreaded sweaty-back feeling you get with cheaper bags. I also appreciated the sternum strap, which can be adjusted for a custom fit and helps stabilize the load during fast-paced walks. At just 3.4 pounds when empty, the backpack is lightweight enough to avoid adding unnecessary bulk, yet sturdy enough to handle heavy loads without sagging.

One unique feature is the ability to stow the shoulder straps and waist belt under a magnetic flap when not in use. This transforms the backpack into a sleek duffel-style bag, complete with padded grab handles for easy carrying. I found this particularly useful when tossing the bag into a car trunk or navigating crowded public transport. The versatility to switch between backpack and duffel mode makes it a standout choice for travelers who value adaptability.

Durability and Weather Resistance – Ready for the Elements

Durability is where the 35L Medium Travel Backpack truly shines. The 400D nylon canvas exterior is tough enough to withstand the rigors of travel, from being tossed into overhead bins to scraping against rocky trails. The bottom of the bag is reinforced with 900D polyester, adding an extra layer of protection against abrasion. During my trip, the backpack endured a surprise downpour, and the water-resistant coating kept my belongings dry without the need for a separate rain cover. The oversized zippers are also weatherproof, ensuring that moisture doesn’t seep into the main compartment.

Peak Design’s commitment to sustainability is evident in the use of 100% recycled materials, but this doesn’t come at the expense of quality. After several months of regular use, the backpack shows no signs of wear, with no fraying seams or fading colors. The brand’s lifetime warranty further underscores their confidence in the product’s longevity, offering peace of mind for travelers who want gear that lasts.

One small note: while the backpack is highly water-resistant, it’s not fully waterproof. If you’re expecting heavy rain or plan to ford a river, you’ll want to pack sensitive electronics in waterproof pouches for added protection. That said, for most travel scenarios, the bag’s weather resistance is more than adequate.

Security Features – Peace of Mind on the Go

Traveling often means navigating crowded airports, busy train stations, or unfamiliar cities, where security is a top concern. The 35L Medium Travel Backpack addresses this with several anti-theft features that give you confidence in any environment. The zippers can be secured with dual locks, preventing opportunistic thieves from accessing the main compartment. Additionally, the zippers can be tucked into a narrow slot, making them nearly invisible from the outside. This clever design reduces the risk of pickpocketing, especially in crowded settings.

The backpack also includes a hidden pocket on the back panel, perfect for stashing valuables like a passport or wallet. During my travels, I used this pocket to keep my phone and credit cards secure while wandering through busy markets. The magnetic flap closure adds an extra layer of security, ensuring that the top of the bag stays closed even if you forget to zip it up. While no bag is completely theft-proof, these features make the 35L backpack one of the more secure options on the market.

Style and Versatility – From Urban to Outdoor Adventures

One of the biggest strengths of the 35L Medium Travel Backpack is its versatility. It’s designed to transition seamlessly from urban environments to outdoor adventures. The sleek, minimalist design makes it a great choice for business travelers or digital nomads who need a bag that looks professional in a city setting. At the same time, the durable materials and ergonomic features make it equally suited for hiking trails or weekend camping trips.

I tested the backpack in a variety of scenarios, from a city break in San Francisco to a hiking trip in the Cascades. In the city, it blended in effortlessly with my casual wardrobe, earning compliments for its sleek look. On the trail, the padded straps and waist belt provided the support needed for long hikes, and the external pockets were perfect for stashing a water bottle and trail map. The ability to switch between backpack and duffel mode added to its versatility, making it a true all-in-one solution for different types of travel.

Price and Value – Is It Worth the Investment?

At around $230, the 35L Medium Travel Backpack by Peak Design is not the cheapest option on the market. However, its premium features, durability, and versatility make it a worthwhile investment for serious travelers. Compared to other high-end travel backpacks like the Osprey Porter 46 ($129) or the Eagle Creek Systems Go Duffel 35L ($139), the Peak Design offering stands out for its innovative design and eco-friendly materials. While budget options like the eBags Mother Lode ($100) are tempting, they often lack the same level of craftsmanship and long-term durability.

For photographers or tech-heavy travelers, the backpack’s compatibility with Peak Design’s ecosystem of accessories adds significant value. The ability to customize the bag with packing cubes, camera cubes, and pouches means you can tailor it to your specific needs, whether you’re carrying camera gear, clothing, or a mix of both. The lifetime warranty also sweetens the deal, ensuring that your investment is protected for years to come.

  • Comfortable Fit: Padded straps, breathable back panel, and removable waist belt ensure comfort on long journeys.

  • Not Fully Waterproof: While weather-resistant, it’s not designed for heavy rain or submersion.

Who Is This Backpack For?

The 35L Medium Travel Backpack by Peak Design is ideal for travelers who value versatility, organization, and durability. It’s perfect for:

  • Frequent Flyers: Its carry-on compliance and suitcase-style opening make it a great choice for air travel.

  • Adventure Seekers: The durable materials and ergonomic design suit hikers and outdoor enthusiasts.
  • Photographers: Compatibility with camera cubes makes it a top pick for those carrying expensive gear.

If you’re a minimalist traveler who only needs a small daypack, this bag might be overkill. Similarly, if you’re on a tight budget, there are more affordable options available, though they may not offer the same level of quality or features.
