Verdict: The Norrøna Trollveggen Gore‑Tex Pro Light Jacket outperforms the Patagonia Triolet in waterproof/breathability performance (20,000 mm/20,000 g/m²/24 h per OutdoorGearLab) and packability, while Patagonia wins on price and sustainability credentials (Patagonia spec sheet, REI). For alpine climbers needing the lightest, most breathable shell, Norrøna is the clear choice; trekkers prioritising cost and recycled materials may prefer the Triolet. Both jackets meet the industry‑standard 20,000 mm waterproof rating, but Norrøna’s slimmer silhouette and tighter seam taping give it a durability edge (Patagonia durability test).
