"Strand-Safe"

Wie kann ich meine Wertgegenstände am Strand sicher aufbewahren, wenn ich schwimmen gehe? Nach langem Suchen bin ich im Internet auf den Flak Sack II von Loctote Industrial gestoßen. Ich befestige ihn an einem der Pfähle des Dühnenschutzes und kann beruhigt ins Wasser gehen. Da so ein Pfahl einen etwas größeren Durchmesser hat, verlängere ich den Verschlußriemen mit einer Drahtschlinge. Möglicherweise könnte dieser Verschlußriemen etwas länger sein. Mit den Kosten für die Lieferung und den Zoll ist der Flak Sack II sehr teuer geworden. Aber jetzt habe ich beim Schwimmen immer ein sicheres Gefühl. Jeder muß selbst entscheiden, wieviel er für die Sicherheit seiner Sachen investieren will.

Nice Tool

The order was uncomplicated and after less than a week I had the part in my hands on Tenerife (Canary Islands - Spain) - compared to many other suppliers super fast and uncomplicated! Even customs and taxes were calculated correctly - which is the big exception! So for the delivery 5 out of 5 points. The packaging was fine and the printed sayings show humor (I don't want to tell you too much, but it's worth opening the packaging at the bottom). Instruction leaflet, instructions etc. were also neat (and the instructions make you smile again). The instructions could be a little more detailed and for some people the instructions in their mother tongue would certainly be helpful. Hence for the packaging and instructions 4.5 points. The Flak Sack II makes a good impression. It is surprisingly "strong", i.e. it makes a very valuable stable impression. Everything is very well made; e.g. the zipper of the inside pocket or the lock is obviously not a cheap product. You can see from the seams, the leather applications etc. that the work has been done carefully and cleanly and that even small details have been executed cleanly. Great ideas such as the pocket for the lock complete the good overall impression. Therefore I give 5 out of 5 points for the processing. It will be difficult if you want to lock the backpack with the locker. You have to pull hard until the eyelets come out. If the lock is hooked in, the backpack is really closed and no one can access the contents from above. Often you don't actually need this, because even if the bag is only closed "normally", the contents cannot be reached without noticeably pulling them apart. A wallet in the zippered inner pocket cannot be accessed unnoticed by anyone imO (locking is of course safer). The two smaller inner pockets are unfortunately the same size and have no Velcro fastener so the contents can slip out. So there is still room for improvement here. You can also do a few "exercises" with a knife and scissors on the enclosed fabric pattern without any risk and realize that the material used is really extremely resistant! The size is sufficient for e-book readers, trays up to 12.3 inches (MS Surface Pro) with power supply unit, etc. The thick material acts like a light cushion, but it does not really offer good protection against falling damage. Upholstery would be useful and desirable here. I therefore give 4.5 points for the functionality as protection against theft, loss and damage. Unfortunately, the possibility to store keys simply and safely is missing. Here, for example, a screw carabiner that is attached to the top lug would be nice. At the end there is the wearing comfort. The two ropes look uncomfortable, but the backpack is surprisingly comfortable to carry even with a weight of 2-3 kg. This is not least due to the ingenious idea with the leather strap for adjusting the lengths. Nevertheless one wishes oneself stretcher cushion however that could be also habit and attitude of me. The small flap at the top for lifting the backpack makes daily handling easier, but could be a little larger. I have a total of 4.5 points. In summary, an excellent overall impression remains. There are some little things to improve, but you have a very good product without real knockout criteria in your hand. Particularly impressive was the recognizable attention to detail and excellent workmanship. I definitely don't regret buying it. In the end, the wish for a larger, well padded version for e.g. cameras, laptops etc. remains. Some of you may wish for trendy colours, funny prints (with the humour of the producers I would be really curious about that). In any case, a world with interesting possibilities opens up here.

Very innovative

The bag is practically indestructible to cuts and abrasion. So addicted to this material, can't wait what they will come up with next. I would like to see more organization al pockets on the inside and hopefully a fully functional backpack in the future.

Amazing

Just started using my bag but for now I'm happy with this amazing bag.

Slash-Proof Fabric

We've created the toughest bags in the world, thanks to our FLAKnit Fabric™. This unique textile is virtually indestrucible yet surprisingly soft. Have peace of mind knowing your belongings are covered by this stuff.

Steel Reinforced Locking Strap

The steel reinforced locking strap enables you to lock your bag shut, and to a fixed object — making it virtually impossible to pilfer or steal without extreme force or heavy tools.

Solid Brass Lock

Lock machined from a single chunk of solid brass to ensure the security for the bag and durability of the lock.

RFID BLOCKING

Protect against RFID theft & electronic pick-pocketing. Our bags include a large internal pocket lined with a certified RFID blocking material to effectively shield credit cards & passports from unauthorized scanning.

Slash-Resistant Ropes

We created a rope unlike any other using slash-resistant material - Ultra High Molecular Weight Polyethylene (UHMWPE). Even though we hope no thief ever tries to cut this bag off your back, it’s nice to know they won’t be successful.

Premium Components & Build

Cheap hardware will ultimately fail. We use stainless steel and brass exclusively for it’s strength, quality and ability to keep looking good after years of use. Our bags are designed to protect but built to last.

Water Resistant

Our bags lined with a Water resistant nylon lining and is equipped with a large (capable of holding an iPad Mini) water-resistant interior pocket crafted with a Aquaguard® zipper to keep your stuff safe & dry from the perils of an active lifestyle.

Sternum Strap

The Sternum Strap gives you that extra bit of security and comfort. By keeping the ropes centered across your chest, the bag stays secure with its weight comfortably distributed across your shoulders.
