Im concidering investing in a micro puff pullover and vest. They are on sale here and there and are recomended on the forums. Dose the Delta break down just from repeated compression or will time (in the warehouse or in my closet) limit its long term usefullness?..woody
I’ve got no personal experience with Delta myself but there’s an interesting discussion on Backpacking.net about synthetic insulation.
Particularly about Delta, the following was said:

Polarguard Delta was light, but there were production and durability issues especially with the 60g weight.
It has been put out to pasture for the new year and will not be produced in 2006. HV and 3D will continue to be manufactured.
Western Nonwovens (polarguard producer) has new continuous filament insulations coming out with clo values similar to Primaloft.
Primaloft Sport: clo .74 , 1.8oz/sq yd 0.4″ loft
Primaloft One: clo .84 , 1.8 oz/sq yd 0.3″ loft
Sport has a higher loft but lower clo value. Also, sport can be quilted every 2 square feet while One has to be very aggressively quilted. Primaloft One, however, has an exceptional clo value.
Style A continuous filament: clo .77 roughly .2″ per oz/sq yd
Style B continous filament: clo .68 2.7oz/sq yd @1″ loft
The delta replacements are fairly typical to work with and are quite good for large panels where quilting can be either eliminated or kept to a minimum. They are typically stiff in hand with a drape that is not as good as primaloft for apparel. Nevertheless, because they can be quilted less some people sacrifice the drape for the ease of construction and fewer quilting lines (and cold spots).
The big question is: what does this mean for the Cocoon stuff ?
