We have tested a lot of backpacks -- and the ultralight pack market in 2026 is the most interesting it has been in years. New materials like ALUULA Graflyte are pushing weights to absurd lows, while established brands keep refining designs that balance comfort, durability, and weight savings without requiring a second mortgage.
Here is our ranked breakdown of the best ultralight packs available right now, from the bleeding edge down to the best values.
## 1. Gossamer Gear Mirage 40 -- Lightest Framed Pack Ever Made
**Weight:** 18.7 oz | **Volume:** 40L | **Price:** $450 | **Frame:** Carbon fiber X-frame
The Mirage is the flagship of Gossamer Gear's new Alchemy line, and it makes a legitimate claim to being the lightest framed backpacking pack on the market at 18.7 ounces. That is lighter than many frameless packs. It achieves this through ALUULA Graflyte V52 fabric -- a mono-polymer, waterproof, seam-taped material that eliminates the need for a pack liner or rain cover.
The carbon fiber X-frame with load lifters provides structure that frameless packs cannot match. The curved trampoline back panel promotes airflow. External pockets are well-designed for quick access to water bottles, snacks, and essentials.
**The honest take:** At $450, this is one of the most expensive packs on the market. And there is a durability trade-off -- Graflyte V52 is lighter than V98 but easier to tear and abrade. If you are a careful packer who treats gear well, the Mirage is extraordinary. If you routinely bushwhack or stuff your pack against granite, consider something more robust.
**Best for:** Experienced ultralight hikers who prioritize weight savings above all else and handle gear with care.
## 2. Gossamer Gear Mariposa 60 -- Best All-Around Ultralight Pack
**Weight:** 34.3 oz | **Volume:** 60L | **Price:** $295 | **Frame:** Aluminum stays
The Mariposa has been a category leader for years, and the current version explains why. At 34.3 ounces for 60 liters, its weight-to-volume ratio of 0.57 oz/L is impressive. But what sets the Mariposa apart is its ability to handle both light and heavy loads comfortably. The aluminum stay frame distributes weight effectively whether you are carrying 15 pounds or 30.
The mesh back panel is one of the best-ventilated in the ultralight category. External pockets are generous. The hipbelt pockets are actually usable (not always a given with UL packs).
**The honest take:** This is the pack we recommend to most people. It does not chase the absolute lowest weight, but it makes almost no compromises in comfort and utility. The Robic nylon body is tougher than any Dyneema or UHMWPE fabric at this price point.
**Best for:** Thru-hikers, section hikers, and anyone who wants one pack that handles varied load sizes well.
## 3. Mountain Hardwear Alakazam -- Mainstream Brand Goes Ultralight
**Weight:** ~22 oz | **Volume:** 45L | **Price:** $475 | **Frame:** Internal stays
The Alakazam is one of the first mainstream outdoor brand packs built with ALUULA fabric, and it brings some smart design choices. The articulated hip belt conforms to movement rather than fighting it. Running-vest-style shoulder straps distribute weight across the chest and shoulders in a way that traditional S-curve straps do not. The oversized side pockets accommodate 1L Nalgenes with room to spare.
**The honest take:** The running vest harness is polarizing -- some hikers love the snug, stable fit, and others find it restrictive. The pocket sizing is also unconventional, with some internal organization choices that feel like form-over-function. At $475, you are paying a premium for the ALUULA fabric and the Mountain Hardwear name. Test the fit before committing.
**Best for:** Hikers who want ultralight weight with a more athletic, body-hugging carry style.
## 4. HMG (Hyperlite Mountain Gear) Southwest 55 -- Toughest Ultralight
**Weight:** 32 oz | **Volume:** 55L | **Price:** $389 | **Frame:** Aluminum stays
The Southwest 55 is built from 100% woven Dyneema -- waterproof, seam-taped, and genuinely tough. This is the ultralight pack you choose when you need weather resistance without a pack cover and durability that outlasts less robust UL fabrics.
The suspension system handles heavy loads better than most packs in this weight class. The roll-top closure is watertight in moderate rain. HMG's construction quality is consistently excellent.
**The honest take:** The Southwest is heavier than the Gossamer Gear options on this list, but the Dyneema body will last significantly longer under hard use. If you hike in wet climates or need a pack that survives years of thru-hiking, this is the strongest choice here.
**Best for:** Hikers who prioritize weather resistance and long-term durability alongside low weight.
## 5. ULA Circuit -- Best Value Ultralight
**Weight:** 39 oz | **Volume:** 68L | **Price:** $265 | **Frame:** Aluminum stays
The Circuit has been a thru-hiker staple for over a decade, and for good reason. At $265 for 68 liters, the value proposition is unmatched in the ultralight space. The frame handles 30+ pound loads without complaint. The hand pockets on the hipbelt are among the best in the industry.
**The honest take:** At 39 ounces, this is the heaviest pack on our list, but it also carries the most volume and handles the widest range of loads. If your base weight is still creeping toward 20 pounds as you dial in your kit, the Circuit gives you room to grow.
**Best for:** New ultralight hikers, budget-conscious thru-hikers, and anyone carrying 25-35 pounds.
