Primaloft Sport
Because of its superior warmth, water repellency amd light weight properties, Primaloft is the single most thermally-efficient insulation available. When wet, Primaloft not only out-performs goose down (the only thing to challenge it when dry), but all other synthetics.
With its water-hating microscopic fibres, Primaloft repels water better than any other synthetic insulation. While it is almost as lofty and light weight as down, Primaloft is also completely hypo-allergenic. Most other synthetics are made of fibres up to 20 times larger than Primaloft, and just as Primaloft''s micro-fibres trap heat better, they are also much softer than their thicker counterparts.
Independent tests have shown that Primaloft is slightly warmer when dry compared to other synthetic insulations, but whereas other insulations lose up to 60% of their thermal retention when wet, Primaloft lost absolutely no insulating value. Primaloft also breathes, making it ideal as an active insulation layer.
Integral uses Primaloft Sport which has proven itself to have the best long term durability and recovery from continuous compression.
