Summary:

• In this episode of the Backpacking Light Podcast, Ryan and Andrew take a deep dive into synthetic insulation: its technology, strengths, weaknesses, and applications.
  • How is synthetic insulation manufactured?
  • Have recent advances been made in modern synthetic insulation fiber manufacturing?
  • What are the limitations of current manufacturing technologies?
  • How do synthetic fibers compare to down plumules?
  • Why choose synthetic over down?
  • How does moisture absorption into insulation compromise its insulating ability?
  • Is rain (precipitation) really the threat to insulation, or are there other moisture sources to consider?
  • Why should synthetic insulation be considered more seriously by ultralight hikers?
  • Should synthetic insulation be considered by hikers who spend most of their time in dry climates?
  • Are synthetic insulations more sustainable than down from a green manufacturing standpoint?
  • How close is the Patagonia Micro Puff Hoody to a down jacket of similar weight?
  • What’s the difference in compressibility between down and synthetic insulation?
  • What type of gear can benefit from synthetic insulation?
• Adventurer, alpinist, backpacker, packrafter, ski mountaineer – and pain aficionado – Max Neale joins them to talk about the Synthetic Insulated Jackets State of the Market report recently authored here.
  • Max talks about risk, uncertainty, and suffering and discusses a trip where the suffering was just a little bit too much while attempting a traverse across the world’s largest mountain.
  • When to use synthetic insulated jackets with active insulation vs. more traditional wind-resistant styles.
  • Windproof vs. waterproof vs. highly air-permeable (active insulation) jackets.
  • Fleece + wind shirt vs. active insulation (synthetic) jacket systems.
  • How to interpret CFM values and why they’re important (or not!) – high vs. low CFM jackets for breathability vs. weather resistance.
  • What is Max’s favorite synthetic insulated jacket, and why?
  • Purpose of synthetic insulating jackets: in-camp use vs. sleep system use vs. hiking use.
  • Are cottage brands really able to compete with big brands with more polished designs and more state-of-the-art technology?
  • Continuous filament vs. short-staple insulation – warm when wet? Durability? How do they compare?
  • Is there a perfect insulated jacket that doesn’t yet exist, and what does it look like?
  • Weight, comfort, breathability, durability, degradation – where are we with technology advancement?
  • Debunking #skurkamyths?
  • Let’s talk about synthetic jacket compression durability/degradation confusion.
  • How does sleeping in your jacket impact insulation durability?
  • What’s the go-to “tough” synthetic insulated jacket (durability?)?
  • At what point do you decide that it’s time to retire your synthetic insulated jacket? Is the answer different for low-permeability vs. active insulated jacket? How can we measure it?
  • What types of compression damage synthetic insulated fibers?
  • What are Max’s big plans for 2018?
• Listener Questions & Tips
  • Is synthetic insulation really warm when wet? Warm when damp, maybe?!
    • Is synthetic insulation loft maintained when small amounts of moisture enter it?
    • What about wearing wet insulating clothing to bed? And what about inside a down quilt? Ack!
    • The problem with compressing a damp sleeping bag/quilt.
  • With the advent of water-resistant down tech, are the advantages of synthetic insulation negated?
    • Description of the down-proof tech.
    • Does it really work? Is it a scam?
    • Where does it work?
  • What’s the best synthetic fiber insulation for moisture transport?
    • The answer lies in the batt construction and batt integration with the overall garment.
  • Why and how to use a synthetic quilt layered over a down quilt/bag for optimal moisture management in inclement/cold conditions – how to use a 2-layered, 22-oz down/synthetic quilt system for an indefinitely long trek in inclement conditions. How about a thru-hike?
