What Is the Best Frameless Backpack in 2026?
Ranked from the RidgeNote register — maker-published weights and current prices, re-read daily. 8 models on this shelf, of 78 backpacks we rank. Updated .
The Gossamer Gear Murmur 36 Hyperlight Backpack - Aluula is the lightest on the shelf at 225 g (7.9 oz), lighter than 100% of the eight frameless packs tracked here and well under the shelf's median weight of 626 g (22.1 oz). It costs $350, matching the median price of $350, so the ounces come at $44.10/oz, far above the median rate of $12.40/oz. Going this light does not cost extra dollars against the median price, but it does trade down in capacity: the Murmur's own stated volume is 36 L, while heavier packs in this group state volumes as large as 50 L.

How to read this shelf
Median weight here is 626 g (22.1 oz, 1.38 lb) and median price is $350, drawn from eight frameless packs RidgeNote tracks against the wider 78-pack shelf. "Lighter than" states the share of this eight-model shelf each pack beats on weight alone: the Murmur 36 Hyperlight Backpack - Aluula sits at the top, lighter than 100% of the shelf, the Hyperlite Mountain Gear Contour 35 at 459 g (16.2 oz) is lighter than 86%, and the ULA Equipment ULTRA Muse Cicada EWP at 800 g (28.2 oz) is lighter than 0%, meaning it is the heaviest model tracked.
The spread from lightest to heaviest is 575 g (20.3 oz, 1.27 lb): the Murmur 36 at 225 g against the Muse Cicada EWP at 800 g. That is a wide range for eight models answering the same buying question, and it means rank alone does not say much without checking where a given pack's weight sits against the 626 g median and what it costs to get there.
The weight-for-money trade
Price ceilings sort differently than rank. Under $250, the lightest option is the Gossamer Gear Skala 38 Ultralight Backpack - Glacier at $225 for 578 g (20.4 oz, 11.04 $/oz), lighter than 71% of the shelf. Under $350, the lightest option is the Murmur 36 Hyperlight Backpack - Aluula itself, at $350 for 225 g (7.9 oz, 44.10 $/oz). Between those two ceilings, the extra budget buys a sharp swing in price per ounce rather than a proportional amount of weight.
The cheapest model on the shelf with a listed price is the Gossamer Gear Fast Kumo 36 Fastpack - S/M at $190 for 586 g (20.7 oz, 9.19 $/oz), lighter than 57% of the shelf. Above the $250 line the per-ounce rate climbs fast: the Hyperlite Mountain Gear Contour 35 asks $350 for 459 g (16.2 oz, 21.62 $/oz), and the Murmur 36 asks the same $350 for 225 g (7.9 oz, 44.10 $/oz). At the top of this shelf, money stops buying grams in a straight line and instead buys a small, specific number of them at a much higher rate.
The middle of the shelf
The Gossamer Gear Fast Kumo 36 Fastpack - S/M lists at $190 for 586 g (20.7 oz), lighter than 57% of the shelf. One rank up, the Gossamer Gear Skala 38 Ultralight Backpack - Glacier lists at $225 for 578 g (20.4 oz), lighter than 71%. One rank down from the Fast Kumo, the Hyperlite Mountain Gear Waypoint 35 lists at $380 for 666 g (23.5 oz), lighter than 43%.
Below the Waypoint, the Tenzing 1200 Whitetail Day weighs 680 g (24.0 oz) with no listed price here, lighter than 29% of the shelf. The ULA Equipment NEW! UltraGrid CDT follows at $200 for 768 g (27.1 oz, 7.38 $/oz), lighter than 14%, and the ULA Equipment ULTRA Muse Cicada EWP closes the shelf at $350 for 800 g (28.2 oz, 12.40 $/oz), lighter than 0%. Across these four ranks price moves in both directions while weight climbs steadily, so rank position and price do not track each other once a reader moves past the two top spots.
Who should not buy the lightest
A maker-published weight and a price per ounce describe what a pack weighs and costs; they do not describe how it carries a given load, how it holds up over repeated trail use, how it handles wet or windy conditions, or how its sizing fits a particular torso. None of that is on this shelf's spec sheet, and none of it should be assumed from the Murmur 36's 225 g figure or any other number here.
A reader choosing between the Murmur 36 Hyperlight Backpack - Aluula at $44.10/oz and heavier, cheaper options like the Fast Kumo 36 at $9.19/oz or the UltraGrid CDT at $7.38/oz is deciding how much they want to pay per ounce saved, not how the pack will feel loaded on day three. That second question belongs to fit, load, and conditions the reader controls, and the spec sheet cannot settle it.

The whole category, every model placed: every backpack, ranked.
What this ranking does not cover
Load-carrying comfort: how a frameless design feels under a full pack weight, including a build as light as the Murmur 36's 225 g, is not something a weight figure states.
Durability: how the fabric and frame-free construction of any of these packs hold up to repeated loading and trail abrasion over a season.
Weather resistance: how each pack's material handles sustained rain, wind, or sun exposure.
Fit: torso length and hip belt sizing, which determine how any of these packs actually rides on a given body.
Organization and access: pocket placement, closures, and how easy a pack is to load and unload on the move.

Elsewhere the spine does not record a per-ounce-saved figure, so the reader should weigh price per ounce, $44.10/oz for the Murmur against $21.62/oz for the Contour, against how much capacity and durability they are willing to trade, which the numbers alone cannot settle.
