I enjoy it

the customs and the state fees were a bit too much. maybe you can make a EU company so we can buy without import fees etc. the products are legit and good!

This is my Favorite Bag of all Time!

They addressed every detail and deficiency I have had with other bags. Plenty of organization. Pockets are deep enough to get things in. Front pockets are roomy (on some bags you can barely get your hand in them but these are roomy without being puffy). The luggage strap is great. The sail cloth is fabulous. Light and water resistant. Zippers appear strong. The loops on the front are very useful. The Faraday features are the icing on the cake. A seriously great bag.

Wow, great quality and fits a whole lot!

When I first found out about this company was when I was planning my first ever trip to France in 2020. I was shopping for a backpack from pacsafe. ( as there bags are locked and hard to get into for pickpockets and even for myself) I stumbled on there SLNT new collaboration with PACSAFE. I really wanted the backpack as it was the perfect bag for trip but it was sold out…so I purchased there shoulder bag. At first before it was delivered I hadn’t really thought much of the bag, I thought it was just going to be any other crossbody shoulder bag. As it arrived too my amazement it came in dust bag as if I was buying from a luxury brand. (So first great impressions) then I gone on to check the rest of the bag out. And just wow, the material on the outside was pretty heavy duty. (so not very easily to be scratched) the first pocket was big enough to put your smaller accessories as well as iPhone pro max. The pocket behind it carried the faraday pouch (which is pretty amazing, nothing can penetrate that pouch. Trust me I tried calling myself with another phone nothing got through. ) Also enough room for another 2 phones or a big wallet. You also get a secret pocket in the back for your passport and important documents, I even fit my wallet. Overall I was so impressed I really wanted that SLNT/PACSAFE back, so when I heard they were releasing the E3 collection, I had to buy the backpack . And once again blown away my expectations. 3 big pockets with little zipper pocket inside as well as a faraday laptop sleeve. I still hope they rerelease SLNT/PACSAFE backpack. As it's a smaller than the E3 and seems like the perfect everyday bag.
