Frequently Asked Questions (FAQ)


How does the sizing work on a Mirage container?

Mirage Systems has standardized our sizing chart for all our products. This makes it easier for all parties involved. A Mirage G1, G2, G3, G4, and the RTS all use the same container size M number (eg. M1, M2, M3, M4, M5, etc.). Each size is designed to hold a compatible pair of canopies (main and reserve). Custom sizing is generally not available. Check our container sizing guide for more information on the sizing of our containers.


I'm only 5'4" tall, and I'm really sick of rigs that hang low over my butt. Does Mirage make a rig that's going to fit my small torso size?

Yes, if the canopies you want to jump aren't too big. We make a version called the S, which are several inches shorter than the standard version of the same pack volume. We make up the extra space by going thicker, which is why we can only do it for smaller canopies, or we end up getting too thick. The largest S rig, the M2S, handles a 150 square foot ZP canopy like the PD Sabre 2 just fine. It will also hold a PD 143R nicely. We do not recommend larger canopies than that for that rig. Because this rig is aimed at smaller people, we've also narrowed the yoke of the rig (width of the neck) as well as taking in the angle of the shoulder straps where they meet the yoke. People of small stature are very pleased with the resulting fit. This rig is NOT intended for use by taller jumpers! The harness geometry will make it quite uncomfortable for those folks.


I'm getting a Sabre-150, but I want a really small rig. Can I get an M0 or even an MT?

You can get one, but it won't be right. A rig that is too small for the canopies being put in it will end up big anyway (canopies are only so compressible) and will look much worse than a larger container would have with those same canopies in it. It's like wearing clothes two sizes too small; it doesn't make you look skinny! Furthermore, rigs don't function as well when they are overstuffed: packing is frustrating, pin tension can be high, loop length is off, bag material can protrude, etc. There is no free lunch in this department. If you want a small rig, you have to get small canopies. But (and this is the big one) if you get small canopies you have to land them. Don't fool around with your safety trying to look cool. Tiny rigs aren't cool, walking without crutches is cool. Visit the sizing guide for more detailed info.


I've had my Mirage for a while, and want to put a smaller main in it. How small can I go?

Good question, and a common one too. Generally you can drop two sizes from the original configuration without too much problem. What happens when you undersize the main is that tension on the main pin becomes too light, and increases the chance of a premature release. This is a very bad situation, and is not worth risking at all. In general, you need to use common sense in judging whether the new canopy will fill out the container properly. Different canopy manufacturing techniques, canopy configurations and local conditions can all affect pack volume. When in doubt, ask a local rigger or instructor who can see your situation first hand.


How do I size my container with a cross braced canopy?

When determining pack volume for cross braced canopies, a good approach is to use the pack volume of a standard construction main that is about 25% larger in area (eg. a 107 cross brace packs like a 135 standard construction canopy). Don't pay too much attention to published pack volume numbers, they are inherently inaccurate and real-world conditions cause actual pack volumes to vary greatly. Look at the feedback that other customers have left on our container sizing guide here to get a real-world perspective of canopy fits.


Mirage Sizing Numbers Explained

We've had so many customers ask us just what the numbers on the inside of their ring cover info mean in regards to our sizing so here is a quick quide to better understand our sizing. This rough guide is considering that you have a hip and chest ring harness. If you have a standard or old style hip ring harness the main lift web number will be roughly 1.5 inches longer.

Typically there are three numbers and will look similar to 16.5, 16, +.5

The first number is the length of your main lift web in inches. A good reference (but rough guide) to go by for the MLW length is this if you have a hip and chest ring harness:


5'3"-5'5" 14"

5'6"-5' 7" 15"

5'7"-5'8" 15.5"

5'9" 16"

6' 17"

The second number is the length of your leg pad in inches.

And the third number is the length of your "stabilizer" or "lateral" as shown below compared to a standard measurement. +.5 means we add 1/2 of an inch to our standard measurement.

You may see one more measurement which is your shoulder extension. That is the length of material that goes from your yoke or neck area up to your 3 ring. The shoulder extension will be longer for thick chested people as the material to cover that distance will be longer. Again, that measurement will be + or - a number compared to our standard. +1 would be a large shoulder extension for thick chested men. That number is always last.
