Compression is tougher on synthetics than down.... The temptation to compress or over compress is higher with synthetics than down, due to its greater bulk.... Got some Cacoon Gear (vest and balaclava) from BPL's new years eve sale.... Both pieces came with warnings not to over compress, first i've seen that.
Note, as a down goods manufacturer I may be considered biased.
