Tanager 20 Sleeping Bag

Feathered Friends

The Feathered Friends Tanager 20 takes the philosophy of ounce-shaving to an extreme by removing the heaviest hardware components entirely: the zipper and the traditional hood. Tailored for dedicated minimalist backpackers and thru-hikers who already carry an insulated hooded jacket, the Tanager functions as an enclosed down tube. By utilizing continuous baffles packed with 900-plus fill power down, it delivers true 20°F capability at a weight that rivals many warmer-rated bags. In practical use, climbing into the Tanager requires shimmying in from the top collar like a sock. While this design eliminates cold spots, zipper failure points, and draft leaks, it limits temperature regulation. You cannot easily vent your feet or open the bag flat during warm evenings. If you encounter nights in the 40s or 50s, the bag can easily overheat. It is an unapologetic specialty tool built solely for maximum thermal output per ounce. **Highlights** - Completely zipperless design removes failure points and weight - Premium 900-plus fill power down delivers deep loft - Continuous horizontal baffles allow custom distribution of down - Simple, fool-proof cinch cord closure at the neck - Significant warmth reserve down to below-freezing temperatures **Watch-outs** - Clumsy entry and exit requires shimmying into the top opening - No venting capability creates overheating risks in mild weather - Requires carrying a warm beanie or hooded jacket to insulate your head

Gear Waratah 28

Gear Waratah 28

Neve

The Neve Gear Waratah 28 is an emerging contender in the ultralight quilt space, appealing directly to hikers looking for boutique design elements without astronomical price tags. Designed with an optional zippered footbox, the Waratah provides the flexible adaptability quilt users love: open it flat on balmy evenings, or zip and cinch the bottom closed when cold air settles into camp. It targets hikers making the transition away from restrictive mummy bags. Independent reviews highlight the Waratah's practical balance of loft, weight, and accessibility. The pad attachment system functions reliably to keep cold side-drafts at bay, though like all open-back quilts, staying warm requires an active setup routine and a sleeping pad with an appropriate R-value. For side and restless sleepers, the freedom of movement makes it far more comfortable than a narrow mummy, provided you manage your draft zones properly. **Highlights** - Convertible design with optional zippered and cinched footbox - Highly competitive price point compared to domestic boutique quilts - Generous cut accommodates dynamic side and stomach sleepers - Thoughtful pad-strap attachment hardware keeps drafts sealed - Packs down small thanks to quality down and thin ripstop nylon **Watch-outs** - Open-backed architecture requires user skill to prevent drafts - Lacks a hood, requiring supplementary head insulation in cool weather - Less established global track record compared to legacy brands
