High-tech synthetic insulations are providing dowm a run for its money in the sleeping bag marketplace, but thay are also creating some confusion.
Although down is still regarded as the premier sleeping bag insulation by most of the hardcore outside audience, retailers report that advances in new synthetic insulations have begun to chase the goose's feathers even at the high-end of the marketplace.
High-tech insulations, including 3M's Lite Loft, DuPont's Micro-loft, Albany International's Primaloft and Hoechst Celanese's Polarguard HV, have reportedly assisted to create new demand in the bag market for quality options to down at competitive rates."DuPont and Celanese have spent a great deal of cash in promoting the fact that synthetics are much better than down when moist. And Albany International's Prima Loft is even trying to sell the oxymoron of 'synthetic down,'" says Jerry Watt, sleeping bag product manager and buyer, Recreational Equipment, Inc (REI). "However, synthetics are getting a lot closer to down--they are about 90 percent of the way there."In some instances, increased recognition of high-quality artificial fills are cutting into the revenue of products down. "From the outdoor sector, we have gone up to now in boosting the worth of synthetic insulation to the customer, that it's getting harder to market," states David Wallace, camping buyer for Blue Ridge Mountain Sports. "Down bags are now out there for only the customer with the most specific of needs."
While comparable in their pursuit of imitating the best attributes of down, artificial insulation manufacturers differ on their strategy. Items like
the Micro-loft of DuPont, 3M's Lite Loft and Polarguard HV have stirred a debate.
Lite Loft, a mixture of polyester and olefin fibers, touts its high-warmth-to-low-weight ratio, in addition to a high degree of loft. On the flip side, Micro-loft claims a high ratio of compressability-to-loft-retention and a high degree of thermal performance, while sacrificing a degree of loft.
Hoescht Celanese requires a different tact with Polarguard HV, a high-void upgrade of its Polarguard continuous filament fiber, which is set to compete on price, durability and loft resiliency.Albany International's Primaloft, made of .5 denier synthetic fibers, is marketed as being as hot as down and warmer than other synthetics at equivalent weights and densities.
Though the differences between the new suits tend to be subtle, retailers say they are altering the way sleeping bags are being sold. "We have trained the consumer previously that the attic of a bag is your best factor for determining temperature rating," states Rich Amodio, sleeping bag purchaser, Eastern Mountain Sports. "But that theory has shifted with the new fills on the market."He adds that before synthetics can match each of the qualities of down, a good deal of confusion will stay in the marketplace. "Most clients appear to be comfortable going with synthetics over down, but there is the potential for a lot of confusion with all the assortment of new lawsuits out there. A well-trained staff will be crucial to the sale."
DuPont is prepared to discuss some of the responsibility for the confusion in retailstores. Accounts director for the DuPont Fiber Fill Group, Robert Van Dyke, worries that the advantages of Micro-loft--heat, compressability and loft retention--need to be worried on the sales floor because the fill comes with a profile."The teachers around the floor need to understand that Micro-loft provides better warmth, although it is not taller. This means more work in the point of sale," says Van Dyke. "The theory on the high tech level is that loft is the most significant, but retailers now have to rethink this issue."
However, some retailers feel that trying to sell the purpose of lower loft with increased warmth will be difficult. "Attic remains the primary driver in the market," states REI's Watt. "How a tote appears and hangs off the shelf remains the primary factor on the market. What gives an edge to Lite Loft is attic. With Micro-loft, people do not understand the less-loft-with-more-warmth ratio."Building a DecisionOn the production end, sellers are choosing insulations based on a mixture of price, functionality and how its bags are positioned on the industry. Sierra Designs, as an example, has introduced six luggage for 1994, such as Polarguard HV versions and also a 650 fill down bag. In general the company has gained a reputation for its use of Lite Loft in its own bags.
"When Lite Loft came out there for clothes, Sierra Designs forced 3M for a sleeping bag version, since the insulation was lighter and more compressible than others available on the market," says Paige Springer, advertising director, Sierra Designs. "We use Lite Loft as our higher-end material. We never fell Polarguard, but we embraced HV. It still has a place as a very durable product and is fantastic for its lower-end camping marketplace."Rather than classifying fills just as high- or low-end products, many manufacturers are choosing insulations predicated on how well they fit their construction methods. The North Face, by way of instance, uses Polarguard HV, which costs nearly half the cost of Micro-loft or Lite Loft. The business states the shingle construction of the insulation provides the most durable.
Marmot, that has introduced a whopping 25 new bags for 1994, utilizes a blend of Lite Loft and Primaloft in many bags, mentioning the insulations' warmth-to-weight compatibility. According to Marmot, Primaloft appears too thin to the consumer to endure alone, or so the company chose to utilize a insulation in the majority of its luggage.MZH's Expedition Trails line remains using DuPont's seven-hole, high-loft Qualofil in the majority of its bags, but plans to include more Micro-loft into future models. The company is producing bags on Qualofil and the inside on the exterior coating for loft.
According to Geila Hocherman, MZH's vice president, Micro-loft is a high performing insulation that needs particular attention. "The issue with Micro-loft is that it cannot stand alone on its own--it depends upon the bag's construction," states Hocherman. "A lot of companies are out to
create the cheapest Micro-loft merchandise as possible. But that's like saying you want to use silk to make a baseball cap." Producers claim that there are some issues with Lite Loft, too. By using both polyester and olefin fibers, manufacturers warn that Lite Loft has a lower melting point than 100-percent polyester insulations, and a higher chance exists for mistreating a Lite Loft bag. "You need to be careful about heat when storing the bag in the back of a vehicle, since the outer layer of insulating material has a lower melting temperature than the interior coating," says Sierra Designs' Springer. "However, just like any piece of technical equipment, you have to deal with it right."And while most of the news in sleeping bags has been dominated by synthetic insulations of late, down is far from dead. Producers are introducing better-performing down bags with greater minimal fill forces (https://www.linkedin.com/pulse/what-types-sleeping-bags-dave-stenie), as well as greater down-to-feather content.
Additionally, the recent debut of DryLoft fabric from W.L. Gore & Assoc. was made to improve down totes by keeping out moisture, while permitting moisture from inside to escape. Many retailers anticipate the high-end techy consumer to go straight for the DryLoft down tote as the businesses' next benchmark of performance.

The program won't make up its own mind.

If you leave it set on Max, that's what it'll ask the drive to burn at.

The best speed (for you) depends on how quickly you want the burn to complete. If you can't wait, burn at max.

If you prefer quality over speed, take the time to try each supported speed and scan the disc to figure out the one that produced the best quality burn.

Half the rated speed seem pretty good to me though - assuming you have the latest media.

If you have older 8x dvds (I.e. Tyg02) or something, I'd burn those at 8x. For me it's generally single layer at 8x and double layer at 4x.
Please don't PM me with questions that should be posted in the forum. I won't reply - Especially if you have post count of 0!!!
