The fall catalog came in the mail today, and the REI Gossamer (new?) jacket and vest listed caught my attention. Pertex Quantum with Primaloft One insulation. The online catalog lists the jacket as 15ozs (the print one said 13), and the vest as 9ozs.
Anyone have any experience with these? Warmth and features as compared to the Micro Puff, MEC Northern Lite, Thermawrap, or UL down?
Gracias,
