Product Insights
The Herschel Kaslo Ecosystem™ Backpack trades premium materials and refinement for an affordable, lightweight 30L carry that fits a 16-inch laptop and weighs just 1 kg from 100% recycled polyester, scoring 9/10 from Reddit as a budget-conscious choice. Compromises include permanently sagging side mesh pockets, loud zipper pulls, a black interior that hides small items, limited water resistance (light rain only), and a tight squeeze under economy seats when fully packed, though it remains comfortable for daily commuting and fits as a personal item on most airlines.
Verified claims
- Capacity
- 30L capacity—over double the Aer City Pack's 14L—fits 16 laptop.
- Construction
- 100% recycled polyester shell weighs just 1 kg, far lighter than Aer's 1680D ballistic nylon.
- Design
- Buyers describe the design as minimal and the logo as discreet.
- Airline fit
- Buyers report the 30L fits as a personal item on most airlines but barely fits under economy seats when packed.
- Daily carry
- The Kaslo 30L weighs about 2.2 lb and is comfortable for daily commuting, per user reports.
- Volume comparison
- 30L capacity more than doubles the standard Aer City Pack (14L) and exceeds the 24L City Pack Pro.
- Pockets
- Buyers report that side mesh pockets sag permanently, so they limit them to light items.
- Zipper noise
- Buyers report that zipper pulls clank loudly; many replace them with paracord or tubing.
- Water resistance
- Per Herschel, water resistant for light rain but not fully waterproof; sustained rain may soak through.
- Interior visibility
- The black interior lining makes smaller items hard to see.
- Material
- Recycled from post-consumer bottles: 600D polyester is flexible, lightweight (1 kg), but less abrasion-resistant than 1680D nylon.
- Comfort
- Buyers report the backpack is very comfortable for daily commuting.
- Organization
- Multiple compartments and minimal design organize gear and blend into any setting.
- Generation
- Kaslo is the previous generation of the Tech Daypack, identical in design and layout.
- Zipper performance
- Standard YKK #8 zippers – smooth daily use and cost savings over weatherproof AquaGuard.
- Overall value
- Reddit consensus rates it 9/10 as a reliable budget-conscious choice.
- Laptop compartment
- 16-inch padded sleeve fits larger workstation notebooks than standard 15-inch limits.
- Size and weight
- 30L capacity and 2.2 lb weight offer spacious yet light carry, but may not fit under all seats.
- Weather protection
- 600D recycled polyester shell resists light rain but standard zippers are not weatherproof.

Reddit Insights
5 threads · r/backpacks, r/onebagReddit users generally praise the Kaslo for its organization, comfort, and minimalist design, but some note durability concerns with side mesh and zipper noise, and many consider Aer backpacks as higher quality alternatives.
Many users are satisfied with the bag's size, organization, and comfort, giving it high ratings, but recurring issues like mesh sagging, zipper clanking, and comparisons to more durable brands lower the overall sentiment.

Watch Out For
Compared To
vs Aer City Pack/City Pack Pro
Aer is often seen as higher quality with better materials and AquaGuard zippers, but more expensive. Kaslo offers a more affordable option with solid organization and a minimalist look.
vs Herschel Tech Daypack
The Tech Daypack is essentially the same bag as the Kaslo Daypack, but made with recycled materials. It is a newer generation, while the Kaslo Daypack is the older version, often found on sale.

User reviews Kaslo quality and notes black interior
I picked up Kaslo. Has YKK 8 zips and seems to be good quality. Only negative is the black interior of the bag makes it harder to see some items in bag.

Positive review with minor concerns about mesh and comfort
Yeah purchased it a few weeks ago. Very comfortable and tons of pockets. I use it as my daily work bag for commuting. Very minimal look and design, no one will notice its a Herschel that cost 150$. The only doubts i have are with the bottle straps on the sides, i don't stress the mesh too much as it seems like it will sag over time... 9/10

User finds 30L suitable for daily and travel, fits as personal item
Hey man, just bought the 30l and I was in the same state as you a few days ago. If that can be of any help, I was wondering if the 30l would be too big for a daily usage since I was planning to use it every day for college but ended up still buying it because I was planning to travel a lot this year. Now that I have it in hands, I don't regret buying the 30l, it isn't that big and can fit my everyday usage but still can carry a lot of stuff. For the plane part, I'm sure it would work

User suggests finding Kaslo to compare with Aer
You might have better luck finding a Kaslo somewhere near you. Should give you a sense how CP2 looks.

Explanation of difference between Tech Daypack and Kaslo Daypack
That is the difference. They switched over to all recycled materials this year, so you’re basically just looking at Gen 1 and Gen 2 of the same bag. The switch happened in the later summer and the old stuff has been on sale to clear it out so that’s why there’s no real reviews on the Tech Daypack yet. Unless recycled materials is really important to you I’d get the cheaper one.
