Seirus Ski

Frequently Asked Questions

• What heated technologies does Seirus use and how long do their batteries last?

  Seirus uses HeatTouch—button-activated heating with three power settings that runs with a compatible 3000Ultra battery (Hellfire models advertise up to ~12 hours on lower settings)—and Heatwave, a dual-stage system that combines kinetic and reflective foil insulation to boost warmth without batteries. Battery life varies by model and heat setting, so check the specific Hellfire product page for tested runtimes.
• How do I decide between gloves, mitts, and liners from Seirus for skiing or backcountry use?

  Choose mitts or heated gloves like the HeatTouch Hellfire when warmth is the priority, and opt for gloves or MagneMitt styles when you need more dexterity and quick access to fingers. Use Dynamax or lightweight Heatwave liners for layering in changing conditions and pair them with a waterproof outer (Weathershield or Xtreme All Weather) for wet-snow days.
• How does the HeatTouch Hellfire compare to the Heatwave ST Whiteout 3N1 Mitt?

  The HeatTouch Hellfire is a battery-heated glove focused on sustained, adjustable heat with premium materials and long runtime on a 3000Ultra battery, offering more continuous warmth and glove-like dexterity. The Heatwave ST Whiteout 3N1 Mitt relies on Heatwave reflective/kinetic insulation and a 3-in-1 modular design for versatile layering and easier on/off warmth without batteries, making it better for variable conditions and multi-day use.
• Are Seirus gloves waterproof and what materials improve performance in wet, cold conditions?

  Many Seirus outers use Weathershield or Xtreme All Weather membranes that are marketed as 100% waterproof and breathable, combined with UltraGrip palms and reinforced high-wear fabrics to maintain grip and durability in wet snow. Insulating layers like LiteWave50, Heatwave reflective lining, and Polygiene odor control help trap heat and manage moisture; for best performance, layer liners with a waterproof shell and dry gear between outings.
• How should I size Seirus gloves, balaclavas, and neck tubes for on-mountain comfort and performance?

  Seirus designs are generally form-fit and stretchable—check the brand’s sizing guide (see seirus.com/map) and individual product pages for S–XXL guidance; choose a glove size that allows a thin liner underneath and enough room for a battery in heated models without excess bulk. Balaclavas and neck tubes should fit snugly against the face for warmth but remain breathable and compatible with helmet and goggle fit.
