The following overview compares two compact carry options designed for short trips and daily urban use. Both bags rely on high-performance materials such as Ultra400X sailcloth and industry-standard components like YKK® zippers and Duraflex® hardware, delivering durability without unnecessary bulk. The description below preserves exact dimensions, volumes, and weights so you can match each model to your travel habits and packing needs. I also explain how the pockets, laptop protection, and carrying systems differ so you can choose the right balance of capacity and mobility.
These packs emphasize thoughtful organization and practical security features. Each model includes a padded, suspended laptop pocket with soft lining that fits up to a 16″ laptop, and both have a hidden smart tracker pocket for location tags. Design choices like a removable keychain, quick-access pockets, and water bottle holders are present, but their arrangement and ergonomics vary between the two packs. Below I break down materials, packing layout, comfort features, and exact measurements so you can see how the 28L and 16 L options compare in real-world use.
Design and materials
At the heart of both designs is the same robust exterior fabric: Ultra400X by Challenge Sailcloth, which provides abrasion resistance and a smooth finish. The Travel pack adds a nylon ripstop interior liner that is bluesign® approved, while the City Pack uses a lighter-weight ripstop nylon interior also certified by bluesign®, offering a slightly lower overall weight. Both models use YKK® zippers—one model specifying waterproof YKK® zippers for increased weather protection—and Duraflex® buckles for dependable attachment points. These material choices prioritize longevity and ease of maintenance for regular urban and travel use.
Capacity and organization
Each bag is optimized for different carrying roles: one for higher-capacity travel and one for daily city use. Important shared elements include a padded and suspended laptop pocket that fits up to 16″ and a hidden smart tracker pocket. The Travel Pack emphasizes packing flexibility with a lay-flat main compartment for quick access and efficient packing, plus dual water bottle pockets and a removable keychain. The City Pack focuses on streamlined everyday carry with a lower volume, quick-grab handles, and a dedicated top pocket for essentials.
Travel Pack 4 Ultra — what it offers
The Travel Pack is tuned for short trips and heavier loads: it provides a lay-flat main compartment to simplify packing, an internal framesheet for structure, and ergonomic shoulder straps with load lifters for more comfortable carrying when loaded. Security features include lockable zippers, a removable, repositionable keychain, and attachment points for an optional hip belt (sold separately). Quick access is handled via front and top pockets, while dual exterior water bottle pockets increase hydration options. Exact sizing: Height 19.25″ (49 cm), Width 12.75″ (32 cm), Depth 8″ (20 cm), Volume 28L, Weight 3.28 lbs.
City Pack 2 Ultra — how it differs
The City Pack streamlines everyday carry with a lower-volume profile and lighter weight. It uses YKK® waterproof zippers to shield contents, and an ergonomic harness system that reduces shoulder strain during all-day urban travel. The pack includes a quick-access top pocket, a single exterior water bottle pocket, and quick-grab top and side handles for flexible carry. The City Pack dimensions are Length 18″ (46 cm), Width 12″ (30 cm), Depth 5.5″ (14 cm), Volume 16 L, Weight 2.13 lbs—making it compact enough for crowded commutes while still carrying a 16″ laptop comfortably.
Comfort, security, and practical details
Beyond materials and layout, both packs focus on usability. The Travel Pack features grab handles on all sides for versatile handling and a luggage handle pass-through for airport convenience, while the City Pack retains a pass-through and quick-grab handles tuned to urban use. Both include a hidden smart tracker pocket and carry protection for electronics via the suspended laptop pocket, which isolates the device from bottom impacts. The Travel Pack adds an internal framesheet and load lifters for heavier loads, and the City Pack emphasizes lower weight and weather resistance through waterproof zippers.
Choosing between them comes down to how much you carry and where you go. If you want a single bag for brief trips with more packing wiggle room and added structure, the 28L Travel Pack fits the bill with its extra pockets and lockable zippers. If your routine is city-focused and you prefer a lighter, sleeker profile while still protecting a 16″ laptop, the 16 L City Pack is a more compact, weather-aware option.
