I have the band below arriving tomorrow. Though, not sure how much more breathable out is compared to other bands. At the end of the day, you’ll always have more band to skin contact surface area than not. And your skin will perspire more where contacts the band. You could wear the strap more loose so skin breathes more… but degrades the HR accuracy. https://www.amazon.com/dp/B095GW12JL/ref=cm_sw_r_cp_api_glt_fabc_2YB5TT3CX0N603A5EX6T
