相較於第一代做了一些改良，袖長比第一代較短，個人比較偏好第一代的袖長長度，但 Base+2.0 同樣是優異的好產品。
It's a very well constructed hat with high quality materials and the reflective aspect is a nice touch. The only complaint I have is with the plastic snap closure, which is fine but for the price I would have preferred a buckle closure instead.
According to the size chart, I should buy a medium but I decided to buy a large expecting it to be roomier. When I received the jacket, I found that it was just fit and a bit tight for a cool weather jacket. Other than that, I am quite happy the jacket.
版型與1.0略有不同，袖長較短，讓人擔心洗完後會不會縮到不合身。
這樣的改變令人意外，且會對未來再次下單造成疑惑。
（至今已購六單以上，再次下單時總常有一些不如預期的狀況）
由於 2.0 的布料的彈性較好，在版型上的確有些微的調整，袖長在 1.0 版本的大數據搜集後，有較多數反應稍微長了ㄧ些，所以我們也小幅度的調整，在布料本身的結構以及大數量的測試後，洗滌後並不會有縮水的問題，請您放心：）
