Sizing Charts
Some armor has default vest sizes. Using a sizing chart you can estimate the closest generic size, however ordering with a sizing form will always give you the most accurate sizing.
Female vests should always be ordered with a sizing for a proper fit. In some cases male vests could be used, but it is usually not recommended.
To estimate your size to the closest generic vest size:
- Measure your chest and add 2, i.e. 40+2=42.
- Measure your waist and add 6, i.e. 38+6=44.
- Pick the larger of the two, in this case 44.
- If you have more than 6 between these two numbers average them out and if necessary round up to the nearest even number, i.e. 48μ40=44.
- Measure your front length while sitting.
- (Clavicle to above the navel)
- 13 to 14 = R and 15 to 16 = L
- If your vest rises up when sitting, the SSBS Neoprene straps can be trimmed to raise the vest.
- NOTE: In this case, please call us so as not to damage the product and void your warranty.
Understand that these are estimations for a quick fit; for a proper fit it's always best to order with a sizing form. The professionals at Body Armor Outlet can walk you through the process if you have any questions.
How to tell if your concealable body armor fits correctly:
Concealable body armor should cover your center mass vitals, and achieve anywhere from a 2 inch gap on each side (for the most mobility) to overlapping of the ballistic panels on the sides where the front and back panels meet (for the most protection).
The first thing to remember when trying on vests is that your front panel should always lay over your rear panel as threats typically come from in front of you, and this ensures that the overlap on the side of the vest is rear facing.
A correctly sized vest will cover you from 1-1.5 inches below the top of your breastbone, to 1-2 inches above your navel (belly button) in length. The width, as mentioned earlier, should achieve anywhere from a 2 inch gap to 1" of overlapping where the front and rear panels meet. Your personal preference may dictate minor variations in comfort, mobility, concealment, and protection.
A vest that is too small for the user will lack the needed coverage to ensure proper protection with large gaps of coverage as well as being too tight and constricting, whereas a vest that is too large will shift, bunch, and crumple while it's being worn, causing pinch points and poor protection. It is a crucial step when buying body armor to ensure that it fits properly so that it performs at its peak level.

Gas Mask Filter Lifetime:
Breakthrough time of a gas mask filter is tested according to EN 14387+A1 at humidity 70% and flow rate 30 l/min, which is equivalent to the volume of air per minute used by an average person carrying out medium heavy work. The approximate lifetime (usage time) of a filter may, under normal conditions, calculated by comparing the concentration at the workplace and the minimum Dynamic Adsorption Capacity (DAC) for the filter.
Gas Mask Filter Storage And Maintenance:
Each NBC-77 SOF gas mask filter is sealed in a plastic bag by the manufacturer. Store the filters unopened in a clean place at even temperature, most appropriate at -5 to +30°C and relative humidity below 80%. Sealed filters tolerate also conditions of -30 to +50°C and RH below 95%. The storage period (month and year) for filters is marked on the filter label. Do not try to regenerate the filters. Never clean the filters with compressed air or compressed water.
Gas Mask Filter Disposal:
After use, gas mask filters are considered special refuse. Make sure that they are disposed of according to the filtered substance (gases or particles) in accordance with current waste treatment regulations. If the product is to be disposed of, it should be dismantled from the respirator and disposed of as solid waste. Please see local authority regulations for disposal advice and locations.
