麻烦推荐夏季顶级速干材质的短袖 - 装备天下 - 8264户外手机版
ECHO 是轻薄，但是化纤材料，在阳光下照耀下会有异味，出汗后穿在身上会不舒服
Echo是真的轻，拿手里感觉都不一样，体感也不错。不过版型是修身型，运动时候还好，平时有时候会觉得有点勒。其实最好就是买了试试。
Echo是真舒适，但只敢做为最内层或睡衣穿。它太轻薄了。。。
Breathability
The Echo is one of the thinnest, lightest shirts we tested. This makes it great for traveling, as it can easily be stuffed into a tight corner of your suitcase or backpack. While it's highly breathable and thin, the lighter colors are a bit see-through with a dark bra or in bright lighting. This shirt could easily keep us warm enough through a crisp early morning run and cool enough while gardening in the hot summer sun. Our lead tester happily wore this shirt to place second in a half-marathon race on a hot weekend when most other competitors stripped down to their sports bras. Truly, this is one of the only shirts we tested that we could comfortably wear to sweat in the blazing sun without feeling the need to push the sleeves up and expose our arms to harmful UV rays.
