Great question — answering as the UphillTech team:
You do not mention your gender, but if you are male and incontinence is urinary only: Consider a "Male External Condom Catheter" or 'Texas Catheter', the volume of required supplies is much lower than diaper type incontinence products, it will also last much longer before needing to be addressed. With a leg bag, you could empty it as needed, and only require a change once a day or so. When you have used a days supply, they are easy to rinse and pack out for disposal, As they don't absorb the fluid they will be much lighter to pack as well. If you are female, you could conceivably use an internal cath, but the I would not recommend it, there are hygiene and abrasion considerations, as well...
