Summit Series uses 800-fill down and expedition-grade technologies like FUTURELIGHT™ waterproof-breathable membranes. Garments feature reinforced stress points and modular layering compatibility, tested by athletes in alpine environments for maximum reliability during ascents or harsh weather.
FUTURELIGHT™ employs nanospun membranes with microscopic pores that block rain while allowing vapor escape. Used in jackets like the Apex Flex, it provides windproof protection without sacrificing mobility, ideal for high-output activities like trail running.
Thermoball™ mimics down’s heat-trapping clusters using synthetic fibres, retaining warmth when wet and packing smaller. Traditional down (800-fill in Summit Series) offers superior warmth-to-weight ratios for dry, extreme cold.
Revive DWR finishes by tumble-drying on low heat or using TX.Direct® spray. Avoid fabric softeners that clog FUTURELIGHT™ membranes during washes.
