Your tactical gear can save a life when it is properly used. If it is worth a life, then you should only choose the best quality out in the market. When a life is reliant on your gear you would never compromise quality over price.
Before buying you would want to determine where you will use it. Different situations require different gears. A good example is a tactical bullet proof vest. There are instances where you will have to sacrifice protection over mobility. Some vest are very heavy. You will not be able to conceal the vest which can make your head the target instead. This defeats the purpose of having a bullet proof vest.
Test everything first in real life. Yes, your gear may look cool on the website or when you receive the package but can it deliver the promise? Are those really waterproof and shockproof? Your tactical gears that are fabric based like modular pouches should be able to withstand scrapes. You’d want to know how exactly they work so that you can rely on them especially when in danger or a life is at stake.
You can only test your tactical gears after you buy so it is recommended to only purchase from reputed brands that has a lifetime warranty.
Understand that these gears are not your normal household gears. They require special maintenance. Take for example the boots. They are made with waterproof materials as well as a very strong leather. Another example is your base layer. Some have anti-bacterial feature which is not machine washable. To ensure it would last for a long time you have to check the manual or ask the supplier how to maintain it.
Learn to look for review first before buying one. There are lot of websites that have actual buyer’s review. This is one of the advantage when buying online.
