![]() It is an extremely long strand fiber, and it is possible that the insulation in a sleeping bag might consist of one continuous strand. Polarguard is the most popular insulation for synthetic sleeping bags. RYAN JORDAN is the Founder/CEO of Backpacking Light Therma-Tek and Primaloft-2.7 (78gm) Thermatek and 133gm Primaloft offer the same loft" The ThermaTek uses a bit different construction so this will be equivalent warmth to the Atom SV. It's spendy because it's just as labor intensive as it sounds, and no one else does anything like it. Thermatek is the Bird's trademark name for taking Polarguard Delta insulation, and then dipping it in DWR, and then LAMINATING it to the face fabric. Another consideration is the construction the insulation is laminated to the inner shell so there are no cold spots from baffle stitching, and this also makes it's loft last longer. "This one is warmer and also will be way better at resisting any moisture pickup due to the totally waterproof Thermatek fill. More to the point I think depending on what is true and what is merely speculation on the author's part: When comparing 2 comparable synthetic down jackets, the higher the g/m^2 However, synthetic insulation is different because the density does not Knowledge of the weight is really important because the density of the down can I was also informed that when determining the warmth of down, ![]() Down being the ultimate combination of both clo and loft.įrequently, to make up for Primaloft having a higher clo, Coreloft has a little The higher loft takes longer to heat the insulation and feel the insulation warm, but there is the potential to trap a lot of heat. In comparison, insulations with high loft, generally have a lower clo for a given weight. ![]() A garment with a high clo value, once on, traps your body heat very quickly. Insulations with high clo values, like down, are very fast acting. ![]() With regards to Synthetic fiber fill there's two factors that relate to warmth. That the accepted standard is Coreloft falling 5% below Primaloft One when tested head to head. Other instances, Coreloft was tested with a lower value compared to Primaloft. In some instances Coreloft was tested and found to have a higher clo value compared to Primaloft. Apparently, there are two standards for testing clo value when it comes to Coreloft and even these tests vary with weight. "Currently, Arc'teryx does not have a recorded clo value for Coreloft. This is a letter from Arcteryx to a customer I have seen: Anyone have an answer they care to share? Just wondering how that price point is some how justified. Enough so you could easily still buy a Gortext or Neoshell and still be ahead with only a 8oz penalty on the Fissoion SL (Super Light?). What am I missing? Because it looks to me like any one of the 100g/m jackets will be warmer (although not water proof like a Goretex garment) and a LOT cheaper. And if it is such amazing stuff as the price would indicate how come there is no comparitive numbers to show us? Where does the high tech Polarguard Delta (aka ThermaTec) fit into that equation? Because 76g/m sure doesn't look very warm compared to 100g/m sitting here at my desk! ThermaTec had better be some amazing stuff. The Rab version has more insulation and it's insulation is 5% better than Coreloft according to the Arcteryx source. But the Generator and the SV both show more insulation thickness. I might believe the Gortex Fission will be the equal to the Generator for warmth. Having both jackets here at hand makes a physical comparison easy enough. Micro-seam allowance (1.I find the difference in retail pricing troubling and the extra weight even more so.Integrated fitted collar panel for added warmth and comfort.Hydrophobic Coreloft Continuous insulation paired with Permeair 20 creates a lightweight, exceptionally breathable, thermally efficient system.Expedition with e3D fit for easy layering, svelte profile and functional articulation.Drop back hem with drawcord and full seat coverage.Die-cut Velcro cuff adjusters reduce bulk, and won't catch or tear off.Redesigned to include an internal mesh dump pocket and a zippered security pocket, Coreloft Continuous insulation and N80p-x 2L GORE-TEX fabric. The hardwearing GORE-TEX outer shuts out rain, snow and wind, and the insulated DropHood and collar add protection and warmth. This improves breathability without sacrificing warmth. Designed for severe weather versatility, the thermally efficient construction pairs Coreloft Continuous synthetic insulation with a highly air-permeable liner to allow vapour to quickly reach the GORE-TEX membrane. The Fission delivers a high level of warmth with waterproof, breathable GORE-TEX protection.
