The Pexpo Oslo Vacuum Flask – 750 ml in Green is the Oslo in a fresh, nature-inspired green — a bottle for those who want the same Scandinavian-influenced design as the grey but with an energetic, outdoors-friendly colour, crafted from food-grade SS 304 stainless steel with Pexpo's proprietary Tri-Ply vacuum insulation technology — three layers of BIS-grade metals (304 stainless steel, aluminium, 304 stainless steel) with vacuum insulation between them — maintaining beverage temperature for extended hours. The flask features a fresh green powder-coated finish exterior, a airtight screw lid with integrated carry strap, and the full safety credentials of a Made in India, ISI-certified product tested to BIS IS 17526:2021 and international EN 12546 standards. Pexpo backs every flask with a 1-year warranty. The green Oslo's fresh colour pairs naturally with outdoor activities — trekking, cycling, and campus use — while the ISI-certified tri-ply insulation ensures the same performance as all Pexpo flasks.
Pexpo's Tri-Ply technology is the brand's differentiating engineering investment — three metal layers rather than the standard two give it a measurable advantage in temperature stability, particularly when the flask is less than completely full. The flask is 100% BPA-free, leakproof, and eco-friendly — a reusable, odour-free alternative to single-use plastic bottles. Food-grade 304 stainless steel inner walls ensure beverages taste clean and fresh with no metallic aftertaste. All Pexpo flasks should be hand-washed with mild detergent, kept away from carbonated and alcoholic beverages, and stored uncovered when not in use for odour prevention.
Pexpo's proprietary Tri-Ply technology uses three layers of BIS-grade metals — 304 SS, aluminium, and 304 SS — with vacuum insulation, providing superior temperature retention compared to standard double-wall construction. Each flask is tested to BIS IS 17526:2021 and European EN 12546 standards.
At 750 ml, this flask is sized for a full office morning, a gym session, or daily travel hydration without refilling. The compact, ergonomic shape fits in most bag side pockets and cup holders, making it an easy daily carry.
The Oslo's integrated carry strap allows hands-free transport across the shoulder or wrist — no separate pouch required. Ideal for commuters, gym users, and trekkers who need both hands free while staying hydrated.
Inner and outer construction from food-grade 304 stainless steel ensures rust resistance, odour neutrality, and zero BPA or chemical leaching. Every sip of water, tea, or coffee tastes as freshly poured, even after hours of temperature retention.
Every Pexpo flask carries ISI certification from BIS and is proudly Made in India. The 1-year warranty against manufacturing defects reflects Pexpo's confidence in the quality of its tri-ply vacuum insulated product line.
