Has anyone seen or tried to make a UG that had removable baffle tubes to customize temp index?
Thought here is the baffles would be lateral and you would have two or three sets of removable thermal tubes that could be mixed and matched to go from 0% to 40%+ simply by changing the tubes out. Might increase the weight 20% but to have one down suspension system to start with in summer at X price and then save money to spend on level 2 and 3 insulation as the year proceeds and temps go south. Or for different hiking/weather/user needs
I have scoured the net looking and do not have the seamstress skills to even try the DIY route. This could be a function patent idea.
Thought I would post here for thoughts or direction to a vendor with something close. Makes more sense than buying, setting up for correct fit and maintaining two or three UQ.
