About the Brand

STM was founded in 1988 just outside of Sydney in the vibrant suburbs of Bondi Beach. Their mission has been and remains to be simple and pure. They want to provide the things that matter for the generation that does them. This mission started when one of the co-founders, Ethan Nyholm, was looking for a bag that would protect his new laptop and complement his style.

Since he didn’t find a pack he liked, Ethan got creative. He slipped his laptop into a padded postal envelope and put it in his hiking backpack. While this was a good temporary solution, he knew he wanted to develop a lasting one. So, he teamed up with his coworker Adina Jacobs and got to work. The result was a backpack design that focused on protecting digital devices and doesn’t look boring.

Nearly twenty years later, the name STM Goods has become synonymous with good laptop backpacks, fitted cases, and accessories. You’ll find their offices scattered around the globe – from Sydney to San Diego, London, and Kuala Lumpur. No matter where you live, you can invest in a company that makes products for the greater good. Enter the STM Trilogy 15″ Laptop Backpack.

STM Trilogy 15″ Laptop Backpack

When it comes to your technology, you don’t want to mess around. Investing in a great quality piece like the STM Trilogy 15″ Laptop Backpack is a great way to protect your gear. And you will look stylish doing it. That sounds like a win-win situation to us. We're going to touch on its aesthetic, design, comfort, durability, and overall quality of the pack.

The Aesthetic

STM Trilogy 15″ Laptop Backpack - Aesthetic

We love the simple style of the STM Trilogy 15″ Laptop Backpack. The bag comes in three color options: black, dark navy, and granite grey. From the outside, you would never be able to tell that it is a laptop backpack. The appearance is minimalist and casual. You could take this anywhere. It goes with just about every look, color, and theme you have in your wardrobe. That is one of the most important things we realized when we are traveling. Versatile pieces will get you so far. It's dynamic and you won't stick out in the crowd as that tourist. Loud, bold pieces are more likely to scream “tourist.”


STM Trilogy 15″ Laptop Backpack - Design

The STM Trilogy 15″ Laptop Backpack from the Stories Collection packs a punch. Designed to keep up with an active lifestyle, it incorporates protective suspended tech cells, reverse coil zippers, and is water resistant. Moving on to the large main compartment, you will find that it offers ample space for your laptop, charger, and any other electronics you may want to store away. The two outside pockets offer a convenient place to store your phone and keys if you want easy access to them.

Go ahead and try to zip the main pocket closed. Once you do, you’ll realize you could have probably added 30% more stuff in there. The main compartment spans pretty much the entire height and width of the bag. You will also find a small compartment off to the right hand side with a covered horizontal zipper. There is also a small pouch that opens near the top as well as a few water bottle pouches on the side.


STM Trilogy 15″ Laptop Backpack - Comfort

Crafted from water-repellent fabric with an extra layer of polyurethane, this bag is ideal to carry around on a rainy or snowy day. If you take a closer look, you’ll see that even the zippers are designed to keep moisture out. One of the main reasons we love the STM Trilogy 15″ Laptop Backpack is because of the straps.

These straps quickly settle into position and they don’t cut into your shoulders. This is due in part that the bag is not loaded to its full capacity. For the most comfortable wear, keep the straps loose. That way, you can just sling the bag on and adjust the straps accordingly after.

Overall Quality of the STM Trilogy 15″ Laptop Backpack

All in all, we’ve got to say it. We love the STM Trilogy 15″ Laptop Backpack. This bag is a solid option for travelers looking to keep their gear safe or simply commuters who need a little bit of extra space. Either way, this bag was designed to withstand all of the elements. It’s comfortable to wear too, which scores it even more points on our list. While there has been some criticism of the aesthetic in reviews, we’re rather fond of its simplicity.
