Frequently Asked Questions
Why is the SQUALL Hardshell suitable for heavy rain?
The jacket uses a TorrentStretch® 3-layer membrane with a 30,000 mm waterproof rating, plus taped seams and YKK® AquaGuard® zippers. This makes it a dedicated waterproof hardshell rather than a simple windbreaker or light weather-resistant jacket.
How breathable is the jacket during active use?
The fabric has a 30,000 g/m²/24h breathability rating and is designed to help move moisture outward during high-effort activity. Underarm ventilation zippers also let you release heat quickly when walking uphill, carrying a pack or moving fast.
What does the TorrentStretch® 3L membrane do?
The 3-layer laminate blocks water from the outside while allowing moisture vapor from the body to move outward. This helps the jacket protect against rain and wind while staying more comfortable than a non-breathable rain layer.
Is it suitable for travel and city use?
Yes. Although it is designed for demanding outdoor weather, it also works well for rainy commutes, travel and technical city outfits. The key benefit is that you get real hardshell protection in a clean, wearable design.
Who should choose SQUALL instead of a softshell jacket?
Choose SQUALL if heavy rain, strong wind and longer exposure are the main concerns. A softshell is often more comfortable for mild weather, but this hardshell is the better choice when reliable rain protection matters most.
