Seirus Hike & Camp

Frequently Asked Questions

• How should I size and layer Seirus Heatwave Performance Base Layers for hiking in variable temperatures?

  Choose the Heatwave weight (Performance, All Season, or Winter) based on activity intensity and expected temps—Performance for high-output hikes, All Season for moderate conditions, and Winter for cold, low-movement sections. These base layers are designed to be form-fitting to wick moisture and work under mid-layers and shells, so size for a snug fit that allows full mobility and layering.
• What technologies in Seirus gear help regulate temperature and manage moisture on long hikes?

  Seirus uses Heatwave fabric constructions and LiteWave50 for balanced insulation and breathability, plus body-mapped ventilation and moisture-wicking fabrics that pull sweat away from skin during sustained activity. Select items also feature SHIELD antimicrobial treatments to reduce odor over multi-day use, and flat-seam or reinforced constructions to maintain performance under repeated wear.
• Are Seirus Magnemask and head/face protection suitable for windy, dusty trail conditions?

  Yes, Magnemask is built from weather-resistant, moisture-wicking materials and uses magnetic attachment for one-handed on/off, making it useful for wind and dust protection on trail sections. Its design promotes breathability while shielding the face, but for very fine dust or extended sand exposure you may prefer a tighter-sealing respirator-style option.
• How should I care for Seirus gloves and base layers to preserve waterproofing and heating performance?

  Machine wash base layers on a gentle cycle with mild detergent and air-dry or tumble low to maintain fabric treatments like SHIELD and breathability; avoid fabric softeners that can reduce wicking. For heated gloves, remove batteries before washing, follow the product-specific wash instructions, and inspect magnetic seams and battery contacts regularly to ensure safe, consistent heating performance.
