JRB No Sniveler (Jacks R Better) for the cold weather (45F-). The versatility to use it as a TQ, UQ or wear it as a serape had me sold. I prefer gear with multiple use ability. The coziness of down in cold weather is nice.
LHBR double layer IX TQ (tttrailgear) for warmer weather (45F+). Lightweight, and doesn't absorb my sweat/moisture on multi-day hikes.
