SIGG Gemstone IBT Thermos 1.1L – Selenite (8736.10)

Uncompromising insulation meets an ultra-lightweight, rugged design. The SIGG Gemstone IBT Selenite 1.1L is a premium, high-capacity vacuum-insulated thermal flask engineered specifically for demanding outdoor expeditions, multi-day trekking, and everyday heavy use. Part of the innovative Gemstone series, its ultra-thin inner steel wall construction yields a significantly lower weight and a more compact profile compared to standard flasks. Wrapped in a sleek, brushed Selenite steel finish with structural reinforcement, this 1100 ml flask is tailored for adventurers who prioritize pack efficiency without losing thermal power. 

Key Features & Benefits

  • Copper-Coated Vacuum Technology: Reinforced with an internal copper layer inside the vacuum chamber to minimize radiant heat loss, keeping your beverages hot for 18 hours or chilled for up to 25 hours.
  • Ultra-Lightweight Gemstone Body: Engineered using innovative thinning tech, the 1.1-litre container weighs just 510 grams, keeping your trekking backpack payload remarkably low.
  • Structural Embossed Grooves: The distinctive concave geometric grooves along the side of the flask drastically improve mechanical strength against drops while enhancing grip security.
  • Reliable Twist-and-Pour Cap: Provides a 100% leak-proof, airtight seal that handles carbonated beverages easily, complete with an external outer lid that serves as a food-safe drinking cup.
  • Premium 18/8 Stainless Steel: Constructed from top-tier, odor-free, and taste-neutral brushed stainless steel that contains absolutely zero BPA, phthalates, or toxic liners. 

Hiking & Outdoor Recommendations

The high volume and featherweight nature of the SIGG Gemstone IBT 1.1L make it a powerhouse on long journeys:
  • Multi-Day Backpacking & Long Treks: The generous 1.1L volume provides ample hot water storage to prep freeze-dried outdoor meals (like Tactical Foodpack) or long-distance hydration on demanding winter trails.
  • High-Altitude Mountaineering: The dual-layer copper shield acts as an emergency safeguard, maintaining temperature in punishing, freezing mountain sub-zero environments.
  • Glove-Heavy Winter Sports: The combination of structural side indentation lines and a texturized exterior allows ski tourers and ice anglers to pour drinks easily without removing thick, insulated winter gloves.
  • All-Day Fishing & Base Camp Kitchens: Completely food-neutral stainless steel makes it perfect for carrying hearty, hot broths or keeping large batches of ice-cold isotonic drinks crisp through summer heatwaves.
