I have 3/4 in both.
I find the Zymes feel to be a much heavier weight material, not as soft, and a bit “sweatier”. Almost like a thin canvas. The Humvees are obviously lighter, softer and not quite as sweaty – they also have better venting which helps. Not had a damage/wear issue with either, though the Zymes feel tougher.
And – being Endura – I need a large size in the Zymes and an XL in the Humvees. Sods Law dictates that I actually have them the wrong way round size wise 🙄
I much prefer the Humvees tbh
If you don’t want the liners, have a search on ebay – both mine came about a tenner cheaper than anywhere else pretty much as new. Or else buy new and sell on the liners, someone will usually take them on here.
