then losing the craft and the drybags and emergency gear, can be somewhat offset by keeping a space blanket (windbreak layer), matches and/or windproof lighter and a compass in your PFD pockets. These should get you through a short hike (less than several miles) and or an overnight in cold temps.
Frankly, if you are wearing a 5/4/3 wetsuit (with appropriate neo mitts and booties, you would more likely be going slow to NOT overheat on the hike. On the hand, if you wet under your drysuit, you may need to hike darn fast to keep yourself warm because you will chill anytime you stop. This would be the opposite of what most would think/claim here.
