Is the SEG28 personal item size compliant?
The SEG28 is a soft-sided pack that complies to personal item size requirements for most airlines. Personal item dimensional requirements vary slightly by airline, which is one of many reasons we prefer a soft-sided pack over hard-exterior luggage. Even when fully packed, the back panel padding has enough give to conform to the luggage measurement apparatus for most airlines, both domestically and internationally.

What size laptop will the laptop pocket accommodate?
The fully padded laptop pocket is easily accessed from the top of the pack. It fits up to 16" laptops from all manufacturers.

Does the SEG28 include a hip belt?
The SEG28 has a removeable hip belt that adds stability while wearing the pack. It is included and easily installed or removed depending on whether or not you prefer it. There are anchor points for a duffle bag style shoulder strap (not included).

Is the SEG28 waterproof?
The SEG28 is built from waterproof materials and has YKK® sealing zippers on all external pockets. This pack is designed to withstand light to medium precipitation for short periods. Outdoor coatings add further protection by letting water slick off the fabric.

Can I use the SEG28 as a daily backpack?
The SEG28 is an excellent daily-carry backpack for people that need organization throughout their day. The segmented pockets lend themselves to organizing by activity or item- isolating work essentials, lunch, a change of clothes, gym shoes, and tech accessories. If you are the kind of person that sets out in the morning for a full day, the SEG28 will quickly make you wonder how you ever got by without it. Most Matador® team members choose to carry a SEG28 for this reason. Combining your daily carry with a travel-ready personal item is efficient and effective, letting you maintain more of your routine when you’re away from home.

How big is the water bottle pocket?
The external water bottle pocket can fit the largest of water bottles, including 1-liter bottles and Nalgenes®.

How long is the warranty?
The SEG28 has a 3 year, Total-Protection-Warranty. SEG28 is built to last—with the highest quality outdoor fabrics, bartack reinforced construction, and strategic patterning that guarantees long-term performance. Equipment in and out of warranty is eligible for free repairs. (Excludes European Union)

Great quality and stylish!

I love my SEG28. It has a ton of space and still works as a personal item while flying. It’s also nice to be able to compartmentalize my things to keep clean and dirty clothes separate or keep shoes from getting clothes dirty. The bag quality is top notch and I especially like the extra safety loop on the zippers to prevent theft.

I love this bag

I was eyeing this bag for a while because I travel internationally quite often and I also carry a uniform with me to and from work everyday. I have now used it for work and an international trips and I am so glad I purchased it. The material is quality and durable. I am pretty hard on my gear and so far this seems like it will hold up well. It fit in all my flights as a carry on even though I had it packed out to the max. To give perspective, I easily fit a large pair of boots, military uniform, toiletries, a jacket, a full size fluffy towel, flip flops, 15inch MacBook, all my electronic cables and such, and hoodie in this bag with no issues. It is comfortable to carry with options to change how you carry if needed. I love it so much I am probably going to purchase the 40L option as well as a deployment bag. Just buy it.

Not designed for smaller bodies

Very uncomfortable, ultra wide-set straps that don't fit small bodies.
