Rab's Zero G Jacket stands out as a climbing- and backpacking-oriented ultralight with an excellent warmth-to-weight ratio and a fit optimized for movement, often priced more competitively than top-tier premium brands. It typically offers greater breathability and a lighter feel than Patagonia's AlpLight and more movement-friendly design than the ultra-warm Feathered Friends entry, though it can be less rugged under sustained abrasion.

"The Rab Zero G is lauded for outstanding warmth-to-weight, high-quality construction, and a trim alpine-oriented fit, although a few buyers call out delicate face fabric and a higher price point. It’s a go-to for mountaineers and fast-and-light users who want maximum performance."

Patagonia's DAS Parka excels for belay scenarios where maximum down warmth and responsible sourcing are priorities, offering full-length coverage and a very warm insulation package that shines during long, cold waits. Heavier and roomier than the Rab and less finely tuned in technical cut than the Arc'teryx Dually, it represents strong value for climbers who choose warmth and sustainability over ultralight performance.

Mountain Hardwear Ghost Whisperer/2 Jacket
The Ghost Whisperer/2 is an ultralight down specialist that competes directly with Arc'teryx on minimum weight and packability but typically undercuts it on price, making it attractive for weight-conscious backpackers. It delivers comparable compressibility and loft for multi-day missions, though it may use slightly less robust face fabrics than the Cerium LT and therefore trades some durability for a lower cost and lighter carry.
