PrimaLoft® Gold Hi-Loft Ultra

Synthetic insulation works best when you need it the most. It thrives in bad conditions, where its superior water resistance and real-life durability are most important. We've been working with it for 50 years, and have repeatedly innovated in this area, from the introduction of hollow fill insulations to the use of continuous filament insulations.While down insulation grabs the headlines for its warmth to weight ratio, loft and comfort, synthetic insulation’s superior route-proof nature means it will keep working when most down insulated kit has given up and gone home. This is why it’s an essential part of our range and a crucial part in any alpinist’s gear cupboard. Stamping your feet at the belay and windmilling your arms to get the blood following as the snow pours down, this is where synthetics earn their keep.PrimaLoft® has been the outdoor industry’s leading synthetic insulation for over a decade. Originally developed for the US military who required an insulation that would work in any conditions and provide the most warmth for its weight, PrimaLoft® soon found its way into the outdoor industry. That PrimaLoft® was patented under the name ‘artificial down’ gives you a good idea of the high standards PrimaLoft® were gunning for.PrimaLoft® Gold Hi-Loft Ultra is the thickest, softest, and most innovative insulation we have seen for many years. It is extremely warm and the fibres are siliconised for water resistance. Like all PrimaLoft® insulations, PrimaLoft® Gold Hi-Loft Ultra uses silicone-treated fibres to ensure exceptional resistance to water, but it is its aerogel-based Cross Core™ technology and unique accordion-like construction (using vertically lapped fibres instead of the more normal horizontal fibre construction) which allows it to trap more air for a given weight of fill and offer better recovery and mobility. Hi-Loft Ultra is a vertically lapped insulation. In other words, the fibres are mostly orientated upwards and it has the perfect mix of durability, warmth, softness, and drape, making it easy to move in. It’s the highest performing insulation that we use anywhere in our range. Read more
