Synthetic insulation works by trapping pockets of warm air, and if you make the insulation too effective at transferring water vapor you’ll find that the pockets of air don’t stick around long enough to warm up. It has to be said, though, that breathability and warmth will always be a balancing act in synthetic insulation. Polartec Alpha is the pinnacle of lightweight, synthetic insulation for active pursuits. Another bonus – Polartec is made out of recycled plastic bottles. This is a much more desirable situation than what other competing jackets have created, especially when they start to use their own proprietary insulations which often are not as good as what comes from the minds at Polartec and other dedicated brands. The particular variation in the Uberlayer is Polartec’s Hi-Pile Alpha, which means that the insulation is ‘piled’ slightly thicker than the standard, resulting in a warmer jacket. The result was a new polyester-based insulation which Polartec has continued to refine since then. In 2012 Polartec announced that they had been contracted by the US military to produce an insulation that could both breathe well when active and retain heat when sedentary. For one, it features absolutely premium materials – Polartec’s Hi-Pile Alpha insulation is, in many ways, the gold standard for versatile insulation. The Uberlayer is an exciting piece for several reasons. These three fabrics, coupled with some careful tailoring and a few select features, are supposed to provide one of the best and most versatile insulating experiences available. This is 30D stretch nylon, offering excellent range-of-motion in all directions.Its foundation is Polartec’s Hi-Pile Alpha insulation at a weight of 98g/m. The outer nylon shell has a DWR, enabling the Uberlayer to function as an outer layer during light precipitation. Most of the inside of the jacket is hung with a polyester mesh.

#UBERLAYER FOR ALPINE USE FULL#
The Uberlayer aims to top the heap of the new synthetic wonderjackets, promising the capacity to handle huge ranges of temperatures under a full range of aerobic loads. Most recently, they’ve come out with a creative new jacket called the Uberlayer. Their insulation game is not as well known, though, despite putting out some very innovative products in recent years. None of them are really ideal for belaying, they are more geared towards active use as the wind will cut through all of them without a shell on top.Outdoor Research is well known for their shells, which often compete for top honors as some of the best shells in the industry. So the Uberlayer is probably about 1/3 warmer and about 1/3 heavier than the Nano-Air, and probably doesn't breath quite as well - but would be more appropriate in colder weather. The Uberlayer seems to be OR's answer to the Nano-Air, although it has 98g/m2 polartec Alpha while the Nano Air has 60 g/m2 fullrange. Not all that warm though - for New England Winters I imagine you would want something warmer. Stuffs into a pocket with a clip loop as well, and has drop in pockets inside which is a nice touch. It is a really well done light synthetic jacket. The stretch panels give it great mobility, but the wind can cut through them when it is blowing.

Same light insulation where it is insulated. The Cathode is basically a Nano-Puff with light softshell panels under the sleeves and on the sides. (The Superlayer seems similar but not the same as the Uberlayer). I have the Cathode but not the Uberlayer.
