WB Yeti vs Wookie Both 20° Rating

[snwcmpr]

What is the difference between a 20° Yeti (6.5 oz fill) and a 20° Wookie (10 oz fill - XL)?
Or any short vs long UQ.
How can they be rated the same temp?
I know the Wookie is a complete UQ, different than most.
I understand the shape differences.

I already have a 20° Yeti.
I have a WBBB XLC 1.7 Dbl

Like ... If I got a 3 season Wookie, is that redundant?


Thanks,
Ken

The temps can be the same as they both provide protection down to 20 but not the same amount of coverage. The Yeti is simply a partial length short quilt which some prefer to shave weight but typically these short quilts have to be supplemented with a foot pad or some other form of insulation which adds back to the shaved weight. I personally do not like any short quilts as my legs and feet freeze in colder weather with these. Maybe in the warmer rater quilts the short quilts will work but it's just not my thing.

That is what I thought.
Waiting for a "Blem" Wookie.
