给数据吧,这两个面料也不算新了,网上有比较和说法,主要的区别就是 alpha 重透气 轻保暖,定位在中层或者说是优化了运动透气的保暖
个人感觉 Polartec 这个公司的 alpha,Neoshell等都能看出它比较会找户外空档
Alpha
the what: optimally transpiring insulation
the why: to minimize moisture build-up within a system
the how: alpha traps heat better when between layers and loses less to moisture
the where: ideally as a mid layer, between other layers (either standalone or combined in the same garment) that interface with the skin and external moisture
Primaloft
the what: minimally moisture compromised insulation
the why: to minimize heat loss due to moisture build up
the how: Primaloft repells moisture better both inwardly and outwardly – sweat and rain
the where: ideally as a combined weather proof layer, using Primalofts moisture blocking properties to back up a light outer shell
喜欢的自己看看下面的也行
