Lightweight Elemental Defense
Highly efficient and highly compressible synthetic down alternative-maximum warmth in extreme cold.
With over 40 years’ experience outfitting adventurers for extreme weather conditions, innovation is at the core of STORMTECH’s culture and values. Our functional and durable outdoor apparel is built using advanced fabric technologies, and smart sourcing and manufacturing. To help our customer easily identify the benefits of our high-performance gear, we have developed a collection of 8 technology icons:
The waterproof icon identifies waterproof fabric. The ‘mm’ rating is a standardized test determined by placing a 1” x 1” tube over the fabric to determine how high (in mm’s) a column of water can be suspended before the fabric leaks. The higher the rating, the higher the waterproofness.
Basic | Level 1: 600mm to 2,000mm
High | Level 2: 2,000mm to 8,000mm
Extreme | Level 3: 8,000 to 15,000mm+
The breathable icon identifies breathable fabric. The ‘g/m2’ rating is a standardized test determined by measuring how readily oxygen and moisture vapor molecules pass through the fabric, under controlled laboratory conditions. The higher the rating, the higher the breathability.
Basic | Level 1: 1,000g/m2
High | Level 2: 5,000g/m2
Extreme | Level 3: 15,000g/m2+
The thermal rating is the temperature range for which the garment is optimally suited.
Mild: +5°C (1°F) to +20°C (68°F)
Cold: +10°C (50°F) to -10°C (14°F)
Extreme Cold: 0°C (32°F) to -35°C (-31°F)
Seam sealing is the application of a specialized waterproof film used to seal seams. Because sewing needles create small holes that will cause the fabric to leak, seam-sealing is used to seal the holes, to make the seam waterproof. Fully seam-sealed indicates that all seams are sealed, to make a watertight outer membrane.
The critical seam seal icon indicates that the seams and junctions most vulnerable to leak under normal conditions - typically the seams on the neck, shoulders, and chest – are sealed. In this case, not all seams are sealed. Critical seam sealing is a suitable technology for most outdoor activities, but full seam sealing is best for extreme weather.
Ultrasonic Welded Seams
Ultrasonic welded seams make a watertight seam using mechanical vibrations above the audible range to ‘weld’ fabric panels together, without any needle punctures from sewing. Ultrasonic seam welding is an advanced manufacturing process and makes an absolute leak-proof seam.
The maximum device size icon indicates the maximum size device that the product device pocket or compartment will accommodate.
RFID block materials effectively block radiofrequency. Chip-enabled cards like credit cards and identification cards can be wirelessly ‘skimmed’ to collect your personal data. RFID block technology protects from electronic pickpocketing, and wireless theft.
