They are holding up pretty well so far. Even in the -45 degree Alaskan cold they are still flexible.
If you could only have one strap...
If you could only have one strap it would be this one. I've used this to pull a heavy cargo sled behind a snowmobile in the Arctic when the hitch broke. I've used these to attach chainsaws and skis to all manner of vehicles. I've even used them to attach several lodgepole pines together to make a 30' pole. The list could go on forever. I never go into the backcountry without one. And they make the most useful gift.
Fantastic for Strappy Ladders
This strap is elastic, but strong. I've been using these to secure items on my truck for well over 6 months and not one failure. Everyone of these have worked spectacularly.
