RE: WHAT? No liner system this year??
mo,
The Savana system is often used as a liner because of it's light weight. Actually it's lighter than the liner was and it's more breathable. I use a Savana set under my rain type gear and I don't know it's there.
You'll also have an extra camo pattern to use in the early season if you want to use it on the outside.
The cost difference is very little.
