@MI-XC ya, that sweat gutr thing wouldn’t work, as you said, and exactly for the reasons @mcneese.chad explained.
I am also a super heavy sweater. I know this sounds a bit stupid, and simple, but I just bought a cheap 6 or 10 pack of terrycloth headbands and wrist bands. I put one HB on, and keep a stack of 2 - 3 of them beside me on my table. Swap them as they saturate. I usually kill 3 or 4 on a 60 min hard WO. As I say, sounds silly, but it really works well! : )
Also, know it’s already been mentioned by @mcneese.chad , but honestly, anyone who has not tried this fan really owes it to themselves to. I’ve never even run it on speed 3/3. Massively improved evaporation & cooling. And super super cheap vs the other great models I’ve seen recommended here.
[My fave for outdoor rides is the Halo headband. The gutr leaves no place for evaporation. The Halo’s gasket stops the eye drips, and the band itself absorbs the sweat, allowing it to sit there and evaporate [if your helmet has enough ventilation]. 60 - 90 min rides in 25 - 30 C, 30 - 60% humidity, near zero eye drips. I don’t get bad dripping until like >30 C, >60 - 75% humidity… when evaporation is barely possible. But the Halo wets out in about 15 - 20 mins on the trainer, and then it’s just dripping. Not enough evap to keep it from dripping, same as the regular terrycloth HBs.]
