Our Top 4 Picks
#1. Hyperlite Mountain Gear 3400 (Iconic Dyneema, Waterproof King)
Price: Around $225-$275 on Amazon | Capacity: 55L (3,400 cubic inches) | Weight: 1.9 lb | Frame: Frameless | Material: Dyneema Composite Fabric
Search Hyperlite Mountain Gear 3400 on Amazon
The Hyperlite Mountain Gear 3400 is arguably the most recognizable ultralight pack on the trail. It’s made from Dyneema Composite Fabric (DCF), which is completely waterproof and weighs dramatically less than traditional nylon. At 1.9 lb for 55 liters, it’s one of the lightest fully-functional packs. The frameless design means you rely on your own back strength and the hip belt to carry weight – recommended max load is 25 lbs. We tested this on the JMT: jammed 25 lbs of gear (sleeping bag, pad, tent, food, water) and carried 15 miles a day for 10 days. The DCF fabric shows no abrasion even after scraping against granite cliffs. The roll-top closure + two side pockets provide easy access. Criticisms: hip belt is narrow and offers limited comfort at heavy loads, no frame means pack shapes to your back not vice versa. But for sub-20 lb loads with torso padding, this pack is glorious.
Pros:
- Incredibly light at 1.9 lb while carrying 25+ lbs well under 20 lb loads
- Dyneema material is 100% waterproof – no rain cover needed ever
- Minimalist design eliminates unnecessary weight; pack disappears on your back
- Roll-top is secure and adjustable capacity from 40-55L depending how much you roll
- DCF won’t absorb odors, stains, or mildew after wet trips
Cons:
- Frameless means you’re carrying the load on your back muscles – not ideal for heavy loads >25 lbs
- Hip belt is narrow foam – less padding than framed competitors
- Dyneema material makes crinkly noise when moving (some find it annoying)
- Expensive: $250+ for a simple sack with no frame
What Real Users Say:
“I’ve put 5,000 miles on my 3400 and it still looks like new. The Dyneema gets scuff marks but they don’t affect performance. Paid the price upfront and it’ll last 10+ years. Best pack money can buy if you’re ultralight.”

“On a 2-week Sierra trip with 30 lb load, my back got tired by day 3 because the frameless pack rubs shoulders. Under 25 lbs though, it’s perfect. Going to add a removable frame stay for tobear heavier loads.”
— Mark D., Amazon verified
#2. ULA Circuit (Best All-Around Framed Pack)
Price: Around $225-$250 on Amazon | Capacity: 50L | Weight: 2.3 lb | Frame: Internal aluminum stays | Hip Belt: Yes (padded, removable)
The ULA Circuit is a celebrated hybrid: it has a frame (aluminum stays) for load transfer to hips, but it’s still incredibly light at 2.3 lb. This makes it comfortable up to 35 lbs – well beyond what frameless packs handle. The Circuit’s front stretch-mesh pocket is perfect for wet gear or quick-access items. The hip belt has significant padding and adjusts to fit various hip sizes. In our 2-week Sierra test with 30 lbs, the Circuit stayed comfortable all day and the weight distribution felt natural. The frame contributes rigidity without bulk – the pack maintains its shape when loaded. The Circuit is a direct descendant of the legendary ULA Ohm, updated with new materials and features. It’s best for hikers who want sub-2.5 lb weight but still carry 4-5 day food carries (25-30 lbs) or have heavier knees/shoulders issues that require framed load management.
Pros:
- Frame stays enable 35 lb carry comfortably – suitable for longer resupply trips
- Padded hip belt with adjustability – transfers weight effectively onto hips
- Front stretch mesh pocket adds 5L of external gear storage without weight
- ULA’s lifetime warranty: free repairs for life, no questions
- Support small American company known for excellent customer service
Cons:
- Front mesh pocket catches wind – loose items can flop around
- No built-in hydration reservoir sleeve (sold separately)
- Not waterproof: while included pack rain cover works, DCF would be better
- Basic shoulder straps – well made but less ergonomic than premium designs
What Real Users Say:
“Married to my ULA Circuit after 4 years of use. Frame makes 30 lb loads feel like 20 lb. Warranty service when a zipper broke: they repaired it free in 2 days. Support small business and gear lasts forever.”
— Andrea F., REI 5-star
“I upgraded to the Circuit from an Osprey Atmos AG 50. While weight reduction welcomed, the Atmos AG suspension is worlds more comfortable with 30+ lbs. But for sub-25 lb loads: Circuit wins. The simple approach – light + functional.”
— Tom L., Backpacking Light reviewer
#3. Gossamer Gear Mariposa 60 (Best Capacity-to-Weight Ratio)
Price: Around $235-$265 on Amazon | Capacity: 60L | Weight: 2.1 lb | Frame: Frame sheet + tubular stays | Hip Belt: Contoured (removable)
Search Gossamer Gear Mariposa 60 on Amazon
The Gossamer Gear Mariposa 60 holds the record for lightest 60+ liter pack on the market at 2.1 lb. It achieves this via a perimeter aluminum frame (two stays that wrap around the pack body) and a hip belt that transfers weight to hips. For thru-hikers or multi-month trekkers who need to carry a week+ of food at 30+ lbs, the Mariposa is made to handle it while remaining exceptionally light. We carried 35 lbs on a 5-day Sierra route: frame kept the pack upright, load bridged on hip belt. The pack uses 500D Robic nylon on bottom/sides with 100D Silnylon body – enough durability for 3-season use but the 100D won’t survive bushwhacking. The features are Ultralight- specific: removable aluminum stays, detachable lid turns into a fanny pack, and side pockets accept 1.5L bottles. The hip belt size adjusts via zipper to fit different body shapes. Downside: no built-in sternum strap, external mesh pocket can sag when empty.
Pros:
- 60L capacity at 2.1 lb – best volume-to-weight ratio among options
- Frame supports 35 lb loads for heavy food carries
- Removable lid becomes standalone fanny pack – dual use
- Gossamer Gear’s lifetime warranty – excellent reputation for repairs
Cons:
- 100D Silnylon body is not burly – avoid abrasive off-trail scrambling
- Frame design can transfer pack weight to hip belt only if loaded correctly
- Fabric is less waterproof than HMG’s DCF – rain cover included but more weight
- Mesh side pockets stretch after season of use – lose tautness
What Real Users Say:
“Mariposa 60 carried 2 weeks of food on our Colorado Trail thru. The 60L size let us avoid using pack liner – everything fit inside. At 2.1 lb we couldn’t believe it carried so much. Got soaked in hail once and the included cover held fine.”
— Chris P., Appalachian Trail Conservancy volunteer
“The hip belt tore after 1,000 miles of use. Contacted Gossamer Gear and they sent a replacement belt free of charge just for cost of shipping. Their customer service is gold.”

#4. Granite Gear Crown2 38 (Best Value, Superlight)
Price: Around $130-$160 on Amazon | Capacity: 38L | Weight: 2.5 lb | Frame: Frame stays | Hip Belt: Yes (removable)
Search Granite Gear Crown2 38 on Amazon
The Granite Gear Crown2 38 is a steal for ultralight hikers on a budget – it’s lighter than ULA and HMG at 2.5 lb while still offering a frame, hip belt, and 38 liters of capacity. The Crown2 series uses 100D Silnylon and simple frame stays (three separate aluminum stays that can be removed). It’s a minimalist approach that prioritizes weight reduction over glove-soft finishes. At $130-160, it’s the cheapest framed ultralight pack that actually works on long trails. We used it on a 3-week PCT section (35 lb food carry initially) and frame performed adequately. The shoulder straps are thin but padded; hip belt transfers decently but feels a step down from ULA’s padding. The pack includes removable lid that converts to a daypack. The biggest selling point: you get “real flled pack” functionality for under $160 – proper frame, removable stays, adjustable torso length via webbing. Not as refined as Gossamer or HMG, but the value is undeniable.
Pros:
- Cheapest of the four at $130-160 but still includes frame + hip belt
- Frame stays can be removed for lighter frameless carry if desired
- Adjustable torso via webbing permits taller/shorter backs
- Lid converts to fanny pack for side trips
- 100D Silnylon is rugged enough for 2-3 seasons of heavy use
Cons:
- Strap padding is less plush than Gossamer/ULA; comfort is adequate not superb
- No external water bottle pockets – you must reach through side mesh
- Pack durability on par with ultralight but not expedition-grade fabrics
- Some zipper alignment issues with lower pockets (common QC complaint)
What Real Users Say:
“Picked up the Crown2 38 for $149 and it’s the best gear investment I’ve made. At 2.5 lb it’s light, carries my 28 lb base weight fine, and I haven’t noticed a difference from my friend’s $250 pack. Frame works, hip belt puts weight on hips, that’s all you need.”
— Sarah C., Pacific Crest Trail thru-hiker
“Shame that Grenite Gear doesn’t check zipper alignment before shipping. Two teeth were misaligned on my hip belt pocket zip after a month. Still used it though – just avoided stuffing bulky items in that pocket.”
— Mike D., Amazon verified
Buying Guide: Choosing the Right Frame Type
Frameless vs With-Frame: Which Gets Your Money?
Frameless packs (Hyperlite 3400) are the lightest option. They rely on a hip belt + your back to carry weight. Best for: baseweights under 25 lbs and terrain that’s not too steep. If you’re doing weekend trips with no heavy food carry, frameless wins in simplicity and weight.
Frame packs (ULA, Gossamer, Granite Gear) use aluminum stays to transfer weight from shoulders to hips. They’re heavier by ~0.4-0.6 lb but much more comfortable with 25+ lbs over 5+ days. Choose if your baseweight is 25-30 lbs or you do longer resupply sections with heavy food.
Capacity: 40-60L, What Size Do I Need?
40L (like Crown2 38L): Fits weekend 2-3 day trips. 20-25 lbs total. No room for luxury items but everything fits.
50-60L: Fits weeklong food carries (5-7 days). 30 lbs total. Allows room for extra layers, camp shoes, food buffer.
Material: Dyneema vs Silnylon vs Robic
Dyneema (HMG) is completely waterproof and abrasion-resistant, but makes crinkly noise. Silnylon (ULA, Gossamer, Granite) is lighter and quieter but needs a rain cover. Robic (ULA’s 210D) is the lightest but can snag on brush.
Budget vs Premium
Under $160: Granite Gear Crown2 38 gets you there.
$200-270: ULA Circuit or Gossamer Mariposa 60 provide premium features.
$250+: Hyperlite Dyneema if you want waterproof and sub-2 lb.
Frequently Asked Questions
Q: How do I measure my torso length for backpack fit?
A: Tilt your head slightly forward. Run a tape measure from the bony bump at base of neck (C7 vertebra) down to where your hands naturally fall on your hips (iliac crests). That distance is your torso length – 18 inches is “medium”, 16″ is “small”. Most ultralight packs have adjustable torso via webbing to accommodate shoulders.
Q: Can these packs handle international flights (carry-on size)?
A: No, not as carry-on. All exceed airline 40L carry-on limits. They’re for backpacking trips only, not flights.
Q: Should I get a frameless pack if I weigh 130 lb?
A: Yes. Body mass helps distribute frame-less loads. Under 150 lbs, frameless works well with good hip belt. Over 200 lbs, consider framed pack for stability.
Q: How long do these packs last?
A: With moderate use (3-4 backpacking trips/year), expect 7-10 years. Materials don’t rot – they fatigue from abrasion and UV exposure. Replace if you see fabric thinning or if frame stays have stress marks.
Q: Is Dyneema really worth the premium?
A: If you frequently camp in rain, snow, or wet climates: yes. Dyneema eliminates rain cover headaches and moisture in pack that could soak sleeping bag. If you mostly camp in the desert: standard Silnylon might be fine (lighter still).
Final Thoughts
For most ultralight backpackers wanting a balance between weight, comfort, and capacity: ULA Circuit remains the gold standard at 2.3 lb. It’s comfortable, durable, backed by lifetime warranty, and carries 25-35 lb loads comfortably for weeklong treks.
For sub-20 lb baseweights in fair weather: Hyperlite Mountain Gear 3400 offers unmatched waterproofing in the lightest possible pack. Budget: Granite Gear Crown2 38 gives 90% of the performance at $130. For maximum capacity with low weight: Gossamer Gear Mariposa 60 is the lightest 60L pack money can buy.
Choose a pack based on your typical trip length and food carry. Weekend 20-lb load: frameless HMG 3400. 5-7 day resupply at 30+ lbs: ULA Circuit. The right pack disappears on your back until you need something from it – that’s the goal.
