Best Ultralight Hiking Packs 2026: What's New, What's Worth It, and What to Skip
4 min readPublished Mar 23, 2026By Editorial Team
The ultralight backpacking pack market went through a genuine materials revolution in the last two years, and 2026 is when the dust is starting to settle. ALUULA fabric — a 100% polyethylene composite fused at the molecular level, no adhesives, no coatings, no delamination — has moved from prototype to widespread adoption. Two packs generating the most buzz right now are the Mountain Hardwear Alakazam and the Gossamer Gear Murmur. We've tracked the reviews, talked to the numbers, and cut through the marketing.
Here's what you actually need to know.
## The State of Ultralight in 2026
If you've been following pack reviews since 2023, you know that Dyneema Composite Fabric (DCF) was the gold standard for ultralight durability. In 2025, ALUULA arrived at scale and the claims were significant: lighter than Dyneema, stronger than Dyneema, fully waterproof without seam taping, and more abrasion-resistant.
Both packs featured here use ALUULA. Both deliver on the weight promise. Where they diverge is in execution — one prioritizes minimalism and trail-proven simplicity, the other prioritizes technical ambition at a price.
## Gossamer Gear Murmur 36: The Smart Buy
The Gossamer Gear Murmur just got its biggest overhaul since launch, and the 2026 version is genuinely impressive. The pack now weighs **7.9 ounces** — strip the removable components and you're at 7 flat. That is not a typo. Seven ounces for a 36-liter backpack.
**What changed for 2026:** The Murmur switched to ALUULA Graflyte V52 fabric. The result is a pack that is waterproof without a separate rain cover, lighter than any previous version, and more durable than the DCF-based original. The familiar features remain: front stretch mesh overflow pocket, cinch-top bottle pockets, roll-top closure, and cord side compression.
**Who it's for:** Experienced ultralight backpackers and thru-hikers who know how to pack light and want a pack that stays out of their way. The Murmur fits torsos between 19-21 inches; if you're outside that range, sizing becomes a conversation.
**The honest limitation:** This is a minimalist pack. There's no frame sheet, no hipbelt load transfer, no sternum strap tension system. For loads under 20 pounds it's exceptional. For loads approaching 25+ pounds, you'll feel the absence of structure on mile 15.
We've tested a lot of packs — this one stands out for what it doesn't add as much as what it does.

## Mountain Hardwear Alakazam 45/60: The Ambitious One
The Mountain Hardwear Alakazam is the more controversial of the two packs, and that controversy is instructive. Available in 45L ($575) and 60L ($595), the Alakazam uses ALUULA shell fabric with a V-shaped aluminum frame, dual-density foam back panel, mesh overlay on the shoulder straps, and an articulated hipbelt. It weighs under two pounds for the 45L version — impressive for a pack with this much structure.
**What reviewers are saying:** The Alakazam has been called "the most interesting backpack design of 2026" by multiple outlets, and that framing tells you something. Interesting is not the same as excellent. The ALUULA construction is legitimate, the harness engineering is ambitious, and the roll-top waterproof design is clean. But the pack has also drawn consistent criticism for being awkward to pack, carrying noise from the stiff fabric, and prioritizing novelty over practical usability on long days.
**Who it's for:** Technical fastpackers and lightweight multi-day hikers who want a structured ultralight pack and are willing to pay a premium to be on the cutting edge. If you're going from trailhead to camp in a single push and back out the next day, the Alakazam earns its weight penalty over the Murmur. For a 10-day thru-hike, the Murmur's simplicity likely wins on fatigue.
**The honest take:** At $575-$595, the Alakazam needs to be exceptional, not just interesting. Current reviews suggest it's not quite there yet. Watch for a revised version in late 2026 or 2027 that addresses the pack-ability and carry-noise issues.
## Other Packs Worth Knowing in 2026
**Zpacks Arc Haul Ultra 50L** — Still the benchmark for frameless ultralight performance. Weighs 1 lb 5.4 oz in Ultra 100X fabric (lighter and more abrasion-resistant than classic Dyneema). If you've already done the work to dial in your base weight under 10 pounds, this is the destination pack.
**Gossamer Gear Mariposa** — The best option if you need to carry variable loads comfortably. Internal frame, adjustable torso, and the ability to handle both 15-pound fastpacking days and 30-pound resupply carries without destroying your shoulders.
**Hyperlite Mountain Gear Southwest 55** — Best durability-to-weight ratio in the market. Cuben fiber construction, minimalist feature set, proven on the PCT and CDT. The 2026 model earned "Most Durable UL Pack" from multiple reviewers.
## How to Choose: Four Questions
**1. What's your base weight?** Under 10 lbs: go frameless (Murmur, Zpacks). 10-18 lbs: light frame options like Mariposa or Alakazam. Over 18 lbs: you may not actually need an ultralight pack.
**2. What's your terrain?** Cross-country scrambles and off-trail routes favor durable fabrics (HMG, Zpacks Ultra 100X). Well-maintained trails with known conditions give you more flexibility.
**3. Do you need waterproofing?** ALUULA packs (Murmur 2026, Alakazam) are inherently waterproof. DCF packs shed water but seams can leak. Standard nylon needs a cover.
**4. What's your budget?** Ultralight has a premium. ALUULA packs run $300-$600. DCF alternatives range from $250-$500. Standard ultralight nylon starts at $150.
## The Bottom Line
For 2026, the **Gossamer Gear Murmur** is the smarter buy for most ultralight backpackers. The ALUULA upgrade delivers genuine performance improvement at a weight that was impossible two years ago. The Alakazam is worth watching, but the current iteration asks you to pay for ambition that hasn't fully landed yet.
