This review is an addition to the former 2-star review. I have been contacted after than one and the team apologized for my troubles and told me they decided to add a new M+ size in the middle. They send me a prototype within a couple of days, as well as a one of the standard types I have been using prior. Prototype fitted perfectly. I guess this is beyond what you can expect from customer support. 🤩 Truly exceptional.
comfortable and breathable
I've used this brand for 3 years and really like the new model without the valve
