| Star Rating | |||||
| Pros | Excellent warmth and weight, well thought out features, horizontal box baffles, generously-sized footbox | Warm for an ultralight bag, simple and versatile design, box baffle construction, waterproof stuff sack | Exceptional warmth to weight, best for FKTs and lightning quick mountain adventures, simple | Closed footbox to blanket versatility, excellent materials and sewing, unique pad strap attachment system | Lightweight, warm, seals well for a quilt |
| Cons | Expensive, not as versatile as a quilt | A little constricting, small foot box, not the best neck draw cord design | Less versatile than other bags, cannot unzip at all to wear as a blanket or dry out, harder to climb in/get out | Slim fit may not work for everyone, slight animal smell when new | Hard to vent, pad attachment system not intuitive |
| Bottom Line | A seriously toasty bag to bring on any adventure that won't feel like a boat anchor in your pack | A top-scoring bag that's warm and versatile enough for full three-season use, while weighing impressively little | Tailor-made for light and fast ultralight backpackers, fastpackers, mountaineers, and FKT enthusiasts that demand both warmth and a light weight | This versatile quilt has a cinch-able and zippered footbox aimed at the serious thru hiker | A very lightweight and warm quilt designed for three season use |
