Top practical and comfortable!


I really like this bra. It is very comfortable, practical and light. I use it almost every day, not just for mountain. It comes without filler or ring. I prefer it that way, but it has little holes to put it in, if you prefer. If you are accustomed to cotton fabric it may seem a bit strange at first, but it is very comfortable (I am quite sensitive to quite a few tissues). It comes pretty packaged, which personally I do not like much for the waste, but most are cardboard boxes that can be recycled.

Great for hiking!


No coverage but comfortable. Looks like you have the option of inserting some sort of a cup, though, which is nice.
