I would apply the old evis first thing in the morning and forget it. Then a few hours later at work I'd start to sweat and it would light me up haha! I've literally applied it in the am then worked up a sweat 9-10 hours later in the gym and felt the burn. The stuff is bad ass.
The newer evis is not so bad though. There's a little burn, but I personally like it. It smells awesome too.
