| 0:00.0 | Howdy everybody. Welcome back to another episode of Gear 30 on the Blister podcast network. |
| 0:10.4 | My name is Luke Kappa. I am the managing editor at Blister, and I'm coming to you from our home base in Elevation Hotel in Preston, Colorado. |
| 0:18.8 | As always, you can check out everything we are doing and reviewing over at blister |
| 0:23.3 | review.com. |
| 0:25.2 | Today's topic comes at an apt time, with temperatures dropping across the Northern |
| 0:29.7 | Hemisphere and many of us starting to grab our puffy jackets out of the closet. |
| 0:34.4 | Odds are, many of those jackets are filled with insulation from Primaloft, which has been |
| 0:39.3 | one of, if not the biggest name in synthetic insulation for decades. But you don't maintain that |
| 0:45.3 | level of relevance for that long without some innovation. And the folks at Primaloft recently unveiled |
| 0:51.3 | several new insulations. And one of those, Primaloft Ultra Peak, is reportedly |

| 1:30.7 | but also offers a ton of useful info to help all of us better understand how and why our insulated apparel actually works. |
| 1:38.8 | We cover everything from Primelof's origins to their expansive current lineup, how synthetic insulations |
| 1:45.8 | have evolved and diversified over the years, the age-old debate between synthetic and natural |
| 1:51.8 | down insulations, including some aspects you might not have already considered, as well as how |
| 1:57.7 | Ultra Peak compares to Primalov's existing insulations, |
| 2:01.5 | the brand's multifaceted approach to reducing the environmental impact of their products, |
| 2:06.5 | how you can get the most out of your existing insulation pieces, and a lot more. |
