So I posted my experience with OES tarps and I thought I should do the same for Arrowhead.
I ordered their marlin spike whoopie package back in March and have used it on two overnight trips, everything is well made and also showed up very quickly. I just got a GT Ultralight for my daughter and decided to go with another whoopie package from Arrowhead. I placed my order late on Friday before Memorial Day and I received everything in exactly one week. Based on these two experiences, I would not hesitate to buy from them again.
