I bought this on sale after summer last year. I have just recently started wearing it as the weather warms. It is a really nice base, better than anticipated. Very soft, disappears when on. Not sure what it will be like at 90+ degrees, but not anticipating any issues. Fits well -- does not gap or stretch below the bib straps as some bases. I was not a fan of the stripe up the middle of the torso, but actually looks good when you partially unzip to dump heat-- not the deal maker, but a nice addition. I am impressed and will look to add another one or two.
