This is absolutely perfect. Ease of loading and unloading along with typical ZPacks quality. Fits great and weighs nothing.

The Bagger is an ultralight frameless pack perfect for bagging peaks in the Adirondacks or for carrying around town. Featuring a small and streamlined design, the Bagger can be packed down small as a secondary pack for summit side trips or used as an ultralight minimalist pack for short adventures into the backcountry.

  • Constructed from a 3.7 oz/sqyd 100D ROBIC® Material.

  • Small and streamlined design.

  • Optional detachable 1" webbing belt available here.

  • Access the contents of the spacious 16L main compartment with a waterproof wrap around zipper

  • Includes a large internal stretchy Lycra pocket great for carrying laptops and tablets.

  • A closed cell foam sit pad measuring 11" x 15.5" (28 cm x 39.4 cm) is included and adds an additional 1 ounce to the total weight of the pack. The foam pads fits inside the internal pocket and provides some cushion and support against your back.

  • A Large external zippered pocket on the outside of the pack is a great place for storing items that you'd like to access quickly.

  • The top of the pack features a spacious zippered pocket, creating the perfect place for storing your phone, keys, or wallet.

  • The pack material is waterproof and is constructed using hydrophobic thread, making the pack highly water resistant.

3.7 oz/sqyd 100D ROBIC®

ROBIC® nylon has very high tensile strength for its weight. The material features a fully waterproof polyurethane coating. The exterior is treated with a C6 durable water repellent. This material is used for the main body of the Sub-Nero.

Weight: 3.7 oz/sqyd (125 g/m²)

5.0 oz/sqyd Lycra® Mesh

This mesh provides a superb 4-way stretch and is a great choice for exterior backpack pockets. It has a relatively light weight for mesh, while being difficult to tear. It can withstand getting caught on branches and other typical abrasion that backpacks are subjected to.  

 5.0 oz/sqyd (169.53 g/m²)

5.3 oz/sqyd 3D Spacer Mesh

This mesh has a three-dimensional structure which allows airflow and adds cushioning. It has a tricot backing so you can't see clear through the holes. We use it on the underside of our backpack's shoulder straps and belts to absorb sweat, add cushion, and add grip. Our 3D mesh weighs less than most other types.

 5.3 oz/sqyd (180 g/m²)

 About 3/32" (2.5 mm)

I bought this as I wanted a day pack without a hip belt but with my other must haves - water bottle holders. Fits nicely with loads of room. Also use this for my non hiking weekends away, perfect size for carry on.

Nice Day Pack!

I recently used the Bagger on a little West to East to West TransSierra hike. Had the pack on for about 44 miles to carry water and snacks. Fit comfortably on my back and carried the weight well. Nice pack for day and side trips when a large pack is not needed.

Almost Perfect!

We have taken it put for a spin twice now, and really love it. It's so rare to find a roomy ultralight pack that includes multiple zipped compartments and generous side pockets that are designed to properly hug and hang onto water bottles. It's just about perfect. Our only issue is that we are hydration pack users and find that a single water bottle on one side leads to a lopsided pack experience. We're planning to ship the pack out to have it professionally altered to add a hook and port hole for a hydration pack. This adds substantially to the totall pack cost but it should then meet our needs for years to come. If we're happy with the outcome, we plan to purchase a second zpack and alter it as well. So! I know this pack was not designed for hydration bladders, but - if it had a basic hook and port hole it would instantly transform into a five-star rock star for us!

Right size with side pockets

I am using this bag for a hut-to-hut hike on the Haute Route in the Swiss Alps. Carries my 10-11-lbs well, but the big side pockets on a pack this size make it stand out. I expect to use this as my go-to day pack: light and packable.

Really pleased with this pack

I have only used it a couple of times so far, but once I got the straps adjusted to fit me, I have been really pleased with it. My hiking partners appreciate the blue color because it makes it easy to spot me. I like the roominess of the pack and how it easy to access everything in it.
