The Dean™ TR 50 Overnight Hiking Backpack

Our 4th gen, most advanced DEAN yet. Labeled at 50L, the TR50 packs the usable capacity of a 60L bag thanks to smart exterior pockets, pouches, and compression straps, with carry on friendly dimensions of 22 × 14 × 8 inches.

Weighing just 3 lb 8 oz (4 lbs with included dividers and raincover), it's built from durable, PFAS free 210D ripstop nylon with an ultralight aluminum frame for strong support without the bulk. An adjustable torso (14–22"), S-shaped straps, and breathable mesh back panel keep you comfortable all day.

The redesigned interior features an expanded upper compartment, front loading access, and removable dividers for easy organization. Outside, you'll find oversized water bottle pockets, large waist belt pockets, trekking pole loops, hydration compatibility, and a sternum strap with safety whistle. Daisy chain loops on the straps let you add accessory pouches (sold separately).

Raincover included, PFAS free and stored in its own bottom pocket pouch.

Will the DEAN TR 50 pack be large enough? I currently use a larger 55–60L backpack. How does your pack compare in size?

The DEAN TR 50 TR is very comparable in overall capacity to many 55–60L backpacks, and in some cases can carry even more usable gear thanks to its efficient packing design, exterior pockets, gear straps, and expandable depth.

Unlike traditional top loading tube style packs, the DEAN TR 50 offers greater flexibility for organizing and accessing gear. The full front opening panel makes it easy to pack and retrieve items inside the main compartment, while expandable compression straps, extra large side pockets, top brain storage, and a separate hydration bladder compartment provide additional options for carrying or organizing items outside the pack when needed.

As a result, many hikers find the usable carrying capacity can equal or even exceed packs with higher volume ratings, while keeping gear easier to access and organize.

Can the DEAN TR 50 backpack or bundles be brought on an airplane as carry on luggage?

Yes. The DEAN TR 50 backpack measures approximately 22 x 14 x 8 inches, which is designed to meet most airline carry on size requirements. In fact, TR stands for Travel Ready, meaning the pack was intentionally designed with airline carry on limits in mind.

For reference, common airline carry on limits include:
• Southwest Airlines: 24 x 16 x 10 inches
• Frontier Airlines: 24 x 16 x 10 inches
• Allegiant Air: 22 x 16 x 10 inches
• American Airlines: 22 x 14 x 9 inches

Since the DEAN TR 50 TR is 22 x 14 x 8 inches, it generally fits within these carry on guidelines.

In addition, the soft shell design with internal frame allows the backpack to flex slightly compared to hard sided luggage, making it easier to place in overhead bins if needed.

As always, we recommend confirming carry on size limits with your airline before traveling.

Is the DEAN TR 50 backpack waterproof?

The DEAN TR 50 is designed to handle wet environments, but it’s not fully waterproof.

The pack is built with PFAS-free, water-resistant ripstop nylon and features YKK water-resistant silicone-coated zippers throughout, providing excellent protection against light rain and damp conditions.

That said, it does not include fully taped or sealed seams, which are required for a pack to be completely waterproof.

For heavier rain or extended exposure to water, we recommend using the included pack raincover.
