簡單來說是TNF與Primaloft合作開發，擅長潮濕氣候用來取代羽絨的新化纖替代產品。

Independent CLO testing by Kansas State University has shown that
Thermoball technology can offer the low weight, loft, warmth, and
compressibility of down with the wet-weather insulating performance
of synthetics.

規格:
body: 15D 33 g/m2 (1.16 oz/yd2 ) 100% nylon (bluesign® approved fabric) /
insulation: PrimaLoft® ThermoBall™ Avg Weight:285 g (10.05 oz)

這一款的功能介紹有提到，Thermoball synthetic有相當於600fp羽絨的保暖效能。
想請問版上有人購買過Thermoball的夾克/外套嗎? (它也有連帽的Hoodie版本)
保暖效能真的有如官網所宣稱，等同於600fp的羽絨?
跟TNF自家100g填充的Primaloft One外套相比有更保暖嗎?謝謝!
