First Impressions

Upon first glance, the Gregory Nano 20 exudes a sense of purpose and technical sophistication. The backpack’s sleek, aerodynamic silhouette and subtle color schemes immediately convey a sense of athleticism and performance, hinting at the level of engineering and innovation that has gone into its design.

Unzipping the main compartment reveals a generously sized interior, with ample space for day-to-day essentials, outdoor gear, and the integrated hydration system. The thoughtful organization of the pack’s various pockets and compartments suggests a well-considered approach to maximizing the available storage capacity, ensuring that users can easily access and manage their belongings while on the move.

What We Like

One of the standout features of the Gregory Nano 20 is its exceptional hydration performance. The integrated 2-liter reservoir, which is designed to be easily refilled and accessed, provides users with a reliable and convenient source of hydration during their activities, whether they’re traversing rugged terrain or navigating the demands of an urban commute.

The pack’s overall comfort and load-carrying capabilities are also noteworthy. The contoured shoulder straps, padded back panel, and adjustable waist belt work in harmony to distribute the weight of the load evenly, ensuring a secure and supportive fit that minimizes the strain on the user’s body, even during extended periods of wear.

Another aspect that impresses is the Nano 20’s versatility and adaptability. The backpack’s sleek, low-profile design and comprehensive feature set allow it to seamlessly transition between different environments and activities, from trail running and day hikes to cycling and everyday commuting. This level of versatility makes the Nano a compelling choice for those seeking a single, high-performance pack that can handle a wide range of use cases.

What We Don’t

While the Gregory Nano 20 is undoubtedly a premium-quality hydration pack, its relatively high price point may be a deterrent for some consumers, particularly those on a tighter budget or who are new to the outdoor gear market. The backpack’s robust construction, integrated hydration system, and comprehensive feature set come at a premium, and it may not be the most accessible option for those looking to minimize their initial investment in hiking and outdoor gear.

Additionally, the Nano 20’s sleek and streamlined design, while contributing to its versatility, may limit the overall volume and organizational capabilities of the pack compared to some of its more purpose-built competitors. While the backpack’s internal layout is thoughtful and efficient, users with a need for extensive storage or specialized compartmentalization may find that the Nano 20 falls short of their specific requirements.
