What I discovered is that the best vac is pulled when the bag is significantly oversized compared to the item when it is a soft item such as a 3x3 or elastic bandage. This obviously adds some mass to the kit, however this particular kit is optimized towards small group adventures instead of fast backcountry trips.
I also found that the vacuum pulled by a food saver is by no means near what is used by commercial manufacturers. I have a few vac sealed roller gauzes, which show less volume than the supplies that I prepared, however the cost is much higher than normal supplies. Thus is my small experiment in gear prep.
Pros:
- waterproof
- smaller size for gear
- supplies will not get contaminated/outer packaging can be cleaned
- can turn round gear into flat gear
- can prepackage procedure kits
cons:
- extra mass
- slower access
