To all FEMALES
- Gender: Female
- Familiarity: I've used it several times
If you are a female with any sort of bust get the M/L. I thought S/M would be fine. And M/L was for large males?.very wrong. To have room for your beacon, bag, bust, and avalung?.you need the M/L. It was designed for a male and crosses right over?.a very uncomfortable spot. Get the larger version for more strap length to finagle the avalung to fit comfortably.
