Well made, good materials throughout the backpack though I tend the like the pack's bottom more than the material used for the upper. Zippers are loosening though the rear laptop slot zippers hit the sleeve for the laptop. It's possible the sleeve isn't closed completely. I wish the sleeves, both for the phone and laptop were a bit more of a fastener than a slot. Both slide out rather easily which is annoying when the pockets are full and you're looking for something. Lastly, I would've like a bit more variety of interior pockets for pens, knives, smaller items and am concerned the two interior elasticized pockets will stretch out or last. This is not a pack I will be using for travel and will only use for daily work commute.Very solid backpack option.

Good Bag

This is a good bag overall for carrying laptop, tablet, etc...

The problem I have with it is that the bag itself is not a faraday bag; only the smaller bags on inside are. There are two smaller faraday bags inside to protect one small laptop or tablet, and a small phone. I would have gladly paid more to have an entire backpack that was a faraday build.


Hi!! Love the Concept of the bag was wondering if you have a Backpack that can hold a Laptop that is 18inches . I hold a laptop that is massive . Brand is MSI TitanGT77 it being so big I haven't found the right bag yet. Hoping you guys do a custom for hit would love to own one

New EDC Backpack

Let’s just say it, this is what we’ve all been waiting for. The pack safe is cool and all but this is the backpack to beat all backpacks. As an adult professional (not a hipster) I’m talking c suit I carry a pack with me everywhere. Up till now it’s been Dakine all the way, let’s just be honest they hold up to the test of time and when they’re worn out make a perfect ruck sack for the trail, but with this new E3 pack I’ll have all my basis covered. We will see how it holds up, but if it’s made with the same quality all my other slnt gear is, I know we’ve got a winner here and in a tech heavy world it will be nice to know that not only are my devices protected, but my body is also protected from any ambient emfs radiating within my pack. Great job guys, I can’t wait to get mine!

Early access and thrilled

Had the pleasure of doing an early review of this backpack and couldn’t be more impressed. This is not bias. I check out a lot of different carry options and think what SLNT has done with the E3 is extremely impressive.

Game Changer!!

I was honored when SLNT reached out to me to try out their new E3 Faraday Backpack. I already have several other SLNT products but this backpack really has it all. To start, it’s made with sustainable materials. I was so happy to see them take a step in this direction. Secondly, it comes with not just one but TWO removable Faraday sleeves! One that my 16inch MacBook Pro fits into perfectly and one for my iPhone 14 Pro. I’ve been using SLNT Faraday sleeves while commuting in NYC for years but these are sure to become my most used Faraday sleeves. The Backpack itself has so many compartments which allows me to keep all my items organized and it still has soooo much room for more thanks to the large main compartment. This product is so versatile and can be used in so many ways. Everyone needs this backpack. Thank you so much SLNT!
