Home Forums Hunting & Shooting Backpack Hunting Opinions on Sitka Jetstream as a outer layer

BW,
So if you need an insulation layer while moving you use the puffy (Kelvin lite hoody) not the Jetstream ?
You are using the Jetstream as a stationary shell; is this correct ?
If so is the Jetstream the only shell you carry ( no waterproof shell ) ?

Thanks
