What Mammut DRYtechnology is
Mammut DRYtechnology is the Swiss brand Mammut’s waterproof-breathable technology, used in its rain shells and hardshell jackets to keep rain out while letting sweat vapor escape. It’s Mammut’s own approach to weather-protective shells, used alongside established membranes like Gore-Tex in their range.
How it works
Like other waterproof-breathable fabrics, DRYtechnology uses a membrane or coating that blocks liquid water while permitting water vapor to pass, paired with a DWR finish so water beads off the face fabric. Mammut offers it in different versions tuned to balance durability, weight, and breathability for different uses.
A hiker choosing a Mammut rain shell sees it uses DRYtechnology rather than Gore-Tex — getting comparable waterproof-breathable protection from Mammut’s in-house tech, and maintaining the DWR so it keeps shedding water and breathing.
How it compares
Both DRYtechnology and Gore-Tex are waterproof-breathable; the difference is that Gore-Tex is a licensed membrane brand while DRYtechnology is Mammut’s in-house technology. Mammut uses both. Performance depends on the specific version and on keeping the DWR maintained.
The bottom line
Mammut DRYtechnology is the Swiss brand's in-house waterproof-breathable technology for rain shells and hardshells — blocking rain while venting sweat, via a membrane and DWR finish in versions tuned for durability, weight, and breathability. It's Mammut's own alternative to (and complement to) licensed membranes like Gore-Tex; maintain the DWR to keep it breathing.
Frequently asked questions
What is Mammut DRYtechnology?
Mammut DRYtechnology is the Swiss outdoor brand Mammut's waterproof-breathable technology, used in its rain shells and hardshell jackets. It keeps rain out while allowing sweat vapor to escape, serving the same purpose as other waterproof-breathable systems. It's Mammut's own approach, used alongside established membranes like Gore-Tex in their product line.
How does Mammut DRYtechnology work?
Like other waterproof-breathable fabrics, it uses a membrane or coating that blocks liquid water from entering while permitting water vapor to pass out, combined with a durable water repellent (DWR) finish on the face fabric so water beads off. Mammut offers it in different versions tuned to balance durability, weight, and breathability for different uses.
How does DRYtechnology compare to Gore-Tex?
Both are waterproof-breathable technologies; the difference is that Gore-Tex is a licensed membrane brand while DRYtechnology is Mammut's in-house technology. Mammut uses both across its range. As with any shell, the real-world performance depends on the specific version and on maintaining the DWR finish to preserve breathability.
