The Exped Radical 45 backpack has carved out a niche for travellers and gear-focused users who value minimalist design, modular carry options, and robust build quality. With a 45-litre capacity and a hybrid duffel-backpack format, it’s positioned as a versatile solution for everything from weekend getaways to gear-heavy commutes. This review dives deep into its construction, usability, comfort, and long-term durability, offering a clear-eyed look at whether the Radical 45 lives up to its name.

Design and Build Quality

At first glance, the Exped Radical 45 presents a clean, understated silhouette. It’s not flashy, and that’s part of its appeal. The bag is constructed from 210D recycled Robic HD ripstop nylon with a carbonate PU coating, offering a 1,500 mm water column rating. This means it’s water-resistant enough to handle light rain or damp conditions, though it’s not fully waterproof.

The materials feel premium without being overbuilt. Stitching is tight and consistent, and the zippers—YKK throughout—operate smoothly without snagging. The bag’s structure is semi-soft, allowing it to compress when under-packed but still hold its shape when full. The minimalist aesthetic is matched by a lack of unnecessary external straps or buckles, which helps keep the weight down and the profile slim.

Carry Options and Modularity

One of the standout features of the Radical 45 is its modular carry system. It can be used as a backpack, shoulder bag, or hand-carried duffel. The padded shoulder straps are stowable, tucking neatly into a rear compartment when not in use. This is especially useful for air travel or storage, where dangling straps can be a nuisance.

The duffel handles are reinforced and comfortable to grip, even when the bag is fully loaded. There’s also a removable shoulder strap for cross-body carry, though it’s not padded and may dig in during longer hauls. The backpack straps, however, are well-padded and ergonomically shaped. They’re not mountaineering-grade, but for urban travel or short hikes, they’re more than sufficient.

This flexibility makes the Radical 45 ideal for users who switch between transport modes—train, car, foot—without needing to repack or reconfigure their gear.

Internal Layout and Storage

Inside, the Radical 45 is refreshingly simple. There’s one large main compartment with a clamshell opening, allowing full access to the contents. This is a major advantage over top-loading packs, especially when packing bulky items or organising gear.

There’s a small internal zip pocket for valuables—passport, keys, wallet—but no laptop sleeve or dedicated tech compartment. This may be a drawback for digital nomads or users who carry electronics daily. However, the lack of internal dividers means the space is highly customisable. Packing cubes, camera inserts, or modular organisers work well here, and the bag’s shape accommodates them easily.

The 45-litre capacity is true to spec. It’s large enough for multi-day travel but compact enough to fit in overhead compartments on most airlines. Users who pack light will find it spacious; those who carry more gear may need to be strategic with their layout.

Weight and Portability

Weighing in at approximately 1.2 kg (2.6 lbs), the Radical 45 is impressively light for its size and durability. This makes it a strong contender for users who prioritise weight savings without sacrificing robustness.

When worn as a backpack, the load distribution is decent, though there’s no hip belt or sternum strap. For heavier loads, this can lead to shoulder fatigue over time. That said, the pack isn’t designed for alpine trekking or long-distance hiking—it’s a travel and gear hauler first and foremost.

Its slim profile also makes it easy to manoeuvre in tight spaces, whether navigating crowded terminals or stashing it under a seat.

Durability and Long-Term Use

Exped has a reputation for building gear that lasts, and the Radical 45 continues that tradition. The ripstop nylon resists abrasion well, and the PU coating adds a layer of protection against moisture and dirt. After months of regular use—commutes, weekend trips, and gear transport—the bag shows minimal wear.

The stowable straps remain functional and secure, and the zippers haven’t lost their smooth glide. The internal lining is robust enough to handle sharp objects like trekking poles or metal cookware without puncturing.

One area to watch is the shoulder strap attachment points. While reinforced, they’re not designed for extreme loads. Users who consistently carry heavy gear may want to rotate carry methods to reduce strain.

Sustainability and Materials

Exped has made strides in sustainability, and the Radical 45 reflects that. The use of recycled Robic nylon and Oeko-Tex 100 certified materials is a welcome move toward eco-conscious design. While it’s not a fully carbon-neutral product, it’s a step in the right direction for gear manufacturers.

There’s no PFC or PFAS in the water-resistant coating, which aligns with current environmental standards. For users who factor sustainability into their purchasing decisions, this adds value without compromising performance.

Use Cases and Versatility

The Radical 45 excels in scenarios where flexibility and simplicity are key. It’s ideal for:

  • Travel: Fits carry-on requirements, easy to stow, and quick to access.
  • Gear transport: Climbing shoes, harnesses, jackets, and tools fit easily.
  • Urban use: Clean design blends into city environments without looking overly technical.
  • Weekend trips: Enough space for clothing, toiletries, and accessories.

It’s less suited to technical hiking, laptop-heavy commuting, or situations requiring rapid access to multiple compartments. But for users who prefer a single, adaptable bag that can handle varied environments, it’s a strong contender.
