Spigen Tough Armor vs. Rugged Armor vs. Slim Armor: Overview

#1 Spigen Tough Armor

Price: $34.99 - $59.99

Materials: Polycarbonate, Thermoplastic polyurethene, Impact Foam.

Spigen's Tough Armor is the seemingly the company's pride and joy form of case protection as it offers the most drop protection out of all the Spigen cases. Not only is it made of two layers (a flexible TPU interior and a hard PC outer shell), but it also includes extra foam inserts. These are placed inside the TPU interior for an additional degree of shock absorption when the phone falls on the ground. Your camera and screen also stay protected from scratches with  Spigen's Tough Armor cases, thanks to the raised lip design – this means that the glassy display and camera remains unscathed when you place it face down.

Granted, it's not the most stylish phone case, but it does a good job at protecting your iPhone from dents, knocks, and scratches. In fact, the case meets the high MIL-STD 810G-516.6 certification for fall protection , coupled with Air Cushion Technology, to ensure your phone doesn't get damaged through daily use or occasional accidents. Spigen Tough Armor case also features a built-in kickstand that easily pops out of its small indentation on the case, making it easy to watch videos or use your phone without needing to hold it.

#2 Spigen Rugged Armor

Price: $19.99 - $39.99

Materials: Thermoplastic polyurethane

Spigen's go-to TPU case for years has been the Rugged Armor. It's not too bulky but still adds protection.The design offers a perfect balance between thin and light design and solid protection. The frame of the Rugged Armor is textured, making it easier to pick the phone up from a table or get a good grip while holding it. Once on the phone, you have solid protection from drops and falls of all kind thanks to Spigen's Air Cushion Technology that absorbs the shock of unexpected impacts.

The case also covers the phone's buttons with protective outer buttons, and it uses a raised lip around the display to keep it from getting scratched. Because of this, you've got full 360° protection. Plus, the Rugged Armor case is offered for most major smartphones. It is one of those cases that's easy to put on, gets out of the way, and does its job really well.

#3 Spigen Slim Armor CS

Price: $39.99 - $59.99

Materials: Polycarbonate, Thermoplastic polyurethane

The Slim Armor CS case combines extreme defense with on-the-go storage. It has a dual-layer design, with a flexible shock-absorbing TPU interior and a hard polycarbonate exterior. Even with this design, it’s a relatively slim case which means not a lot of bulk for your pockets.  Air Cushion Technology are also packed into every corner of this phone case for bolstered drop-defense.

If you want utility from your phone case, the Spigen Slim Armor CS case includes a sliding card slot on the back of the phone. It’s designed to hold up to two credit or debit cards and/or a small amount of cash when closed. Unfortunately, this Spigen case is not available for a lot of smartphones, so if you don’t have one of the latest flagships, you might be out of luck.

Spigen Tough Armor vs. Rugged Armor vs. Slim Armor CS: Side by Side Comparision

1. Design and Materials

The Spigen Tough Armor consists of a TPU inner shell and a polycarbonate backplate. Air Cushion and foam technology inside add an extra layer of resistance against drops, shocks, and scratches. The case also has raised lips to protect both the screen and the phone’s cameras. Being able to prop your phone up is definitely a feature that some users appreciate. The Spigen Tough Armor case has a tiny, long rectangular built-in kickstand on the bottom, right. Pop it out and prop the phone up in landscape mode to watch videos, make a video call, or work hands-free. Once the kickstand is in position, it does hold the phone sturdily and offers a good horizontal angle.

Spigen Rugged Armor case is made out of Thermoplastic polyurethane (TPU). TPU material makes it extremely flexible but also very protective. It is extremely easy to take on and off due to flexible design. It's certainly not the thinnest case you can buy, but considering the level of protection it offers, it's a pretty compact form factor.

Spigen chose a dual-layer design for the Slim Armor CS, including a TPU interior that helps with shock absorption and a hard polycarbonate exterior to keep it sturdy and rigid. The end result is a case that's ready for just about anything and feels like it was built with care and attention. The exterior card slot definitely steals the show on the Spigen Slim Armor CS case.  You'll find a door the slides open on the back to reveal the hidden compartment for your cards. Spigen says the Slim Armor CS can hold up to two cards at a time, but I managed to store three (two debit cards and an ID) without a problem.

2. Protection

Spigen Tough Armor case offers rugged protection, meeting military standards for drop protection (MIL-STD 810G-516.6) . What this means is that the Spigen Tough Armor has been put through various iterations of testing to simulate certain conditions like shock and vibration. The flexible interior is soft and ensures your phone doesn't get scratched while inside the case, while the exterior is durable and features impact foam for shock absorption.  The Tough Armor is the toughest case from Spigen.

After my excessive use and tests, I conclude that, Rugged Armor case gives confidence and looks fairly protective for my phone. There are multi-layered bumper protection on all corners.Air cushion technology provides extra protection support from falls. Phone’s buttons are also protected by outer case buttons.

The Spigen Slim Armor CS case offers ultimate protection for your phone against bumps because it features Military Grade Drop Protection standards MIL-STD 810G-516.6 and Air Cushion technology in all corners. The raised edges ensure your camera lenses don't touch the surface if you place your phone down, and won't get scratched as easily in your bag.

Bottom Line 

Rugged Armor provides good protection with an affordable price. For most people, it is a safe choice that won't disappoint. It’s not the flashiest or the most protective, but you won't find a better value.

The Tough Armor case is the most resistant and expensive case the company Spigen offers. It is pretty bulky compared to the rugged armor. But if you want as much protection as possible from your Spigen case, the Tough Armor is the one.

Protective case and hidden wallet in one package. The Spigen Slim Armor CS is for people that like stretching their dollars as far as possible.
