FAQs

Please read our FAQs page to find out more.

How is the ElementFlex different from traditional hard shells?

The ElementFlex Hardshell is engineered to deliver full weather protection without the stiffness, noise, or heat buildup typically associated with traditional hard shells. Its 3.5‑layer laminate blocks wind and rain while allowing vapor to escape, and 4‑way stretch construction enables unrestricted movement. Integrated 37.5®️ Technology actively manages heat and moisture to keep you comfortable during changing conditions and high‑output activity.

Is the ElementFlex Hardshell waterproof or just water-resistant?

The ElementFlex Hardshell is designed for full weather protection. Its 3.5‑layer laminate construction sheds wind and rain while maintaining breathability, and water‑resistant YKK®️ AquaGuard®️ zippers help seal out moisture at critical entry points. A PFAS‑free C0 DWR finish adds additional water repellency without harmful chemicals.

How breathable is the ElementFlex Hardshell during active use?

ElementFlex is built for movement and heat regulation. The shell allows vapor and air to escape while underarm vent zips provide rapid heat release when exertion increases. 37.5®️ Technology works continuously to regulate body temperature and accelerate drying, helping maintain comfort across a wide range of activity levels and environments.

Is the ElementFlex made with PFAS-free materials?

Yes. The ElementFlex Hardshell uses a PFAS‑free C0 DWR (Durable Water Repellent) finish. This provides effective water repellency without the use of per‑ and polyfluoroalkyl substances, supporting both performance and responsible material choices.

"I’ve owned a lot of hard shells over the years, but this is one of the most comfortable I’ve ever had. It moves with you, stays quiet, and doesn’t trap heat like most rain jackets. I wore it in steady rain and strong wind and stayed dry without overheating."

"The Element Flex handles movement and weather better than expected. The vents dump heat fast when you’re working, the hood doesn’t block my vision when it’s up, and the fabric feels durable but not stiff. This is exactly what I want in an all-day shell."

"I wanted a shell that could handle rain and wind without feeling heavy or crinkly. The ElementFlex delivers. It packs easily, stretches comfortably, and stays breathable during longer treks and activity."
