For incontinent men, hot weather brings on the added "WET" of sweat to mix with urine. You may want to consider wearing a penile clamp while you are active and hot. Empty your bladder every hour or so and re-clamp. Limit the activity to two hours, remove the clamp, and cool off; wipe off the sweat and other WET.
I use an external catheter with a drain tube and a leg bag. That prevents urine wetness from the crotch and legs. However, the sweat will shorten the time in which the catheter will remain in place (the glue will soften and slide off). But, you may get as much as six hours of use before the catheter removes itself. With light movement, I get at least 12 hours of stable use before washing, drying, and replacing the catheter.
If you want to continue beyond the limit of the external catheter, simply apply the clamp over the external catheter to extend the time. The external catheter will keep your bladder drained so that when you apply the clamp, you are beginning clamp time with an empty bladder.
Changing from pads and pull-ups to an external catheter requires determination and dedicated effort until it becomes a part of you.
The change-over actually requires a change of mindset. It's not a piece of cake but it IS DOABLE and the results (for me) are worth the extra effort.
