J1L is the long form extended play J1A (Gen. 2.2 base).
J1A was the first ever jacket designed by Acronym. Originally conceived in the years between 1999 and 2001, it is the progenitor of the Type 2371*, and of every other Acronym jacket that has followed.
J1A-GT is the culmination of everything we have learned about building apparel since that time. Everything is new. Everything is the same. The very idea of ACRONYM rendered in physical, wearable form. A carefully balanced array of functional and aesthetic systems presented here in completely remastered form. Asymmetric. Dynamic. ACRONYM among equals.
Combine with 3A-1, 3A-2, 3A-3TS, or 3A-13TS for full INTEROPS functionality.
Built with next generation Gore-Tex® Pro fabric technology for improved ruggedness, increased breathability, and greater comfort in more conditions.
