Eberlestock Brooks 3500
The Brooks 3500 is an attachment bag, not a complete pack: 3,626 cu in (about 59 liters) of roll-top storage that mounts to Eberlestock's Mainframe II or Modframe, both sold separately. The bag is $189 and either frame is $349, so the two bought separately come to $538, but Eberlestock sells the bag bundled with either frame for $457.30.

Features
Pros
- ✓At 1 lb 15 oz for 3,500 ci it offers better volume-to-weight than Eberlestock's own Vapor bags.
- ✓It opens both ways — roll top and a full front zip panel — fixing the front-only access owners complain about on the Vapor.
- ✓It has a proper rear hydration sleeve with side hose ports plus three interior sleeves, which the Vapor 2500 lacks entirely.
- ✓Its 16 reviews are genuinely product-specific, unlike the Vapor's review pool which is shared across the whole Vapor line.
- ✓The roll top lets you run the bag half-full without a sloppy load, then expand when you need the volume.
- ✓Bundled with either a Mainframe II or a Modframe it lands at $457.30, well under an equivalent Stone Glacier or Exo system.
- ✓Owners report it attaches cleanly to the Mainframe and stays comfortable over long hauls with heavy loads.
- ✓The modular frame approach means one frame serves multiple bags, and Eberlestock's US-based support gets consistent praise.
Cons
- ✗The frame is not included, so the real entry cost is $457.30 as a bundle ($538 bought separately) rather than the $189 shown on the bag.
- ✗No lid is included — the larger Brooks 7000 ships with one, and owners find the omission on the 3500 hard to explain.
- ✗The roll top eats the advertised capacity; one owner measured it short of 36 inches and doubts it is a true 3,500 ci bag.
- ✗Published volume contradicts itself across Eberlestock's own listings — 3,500, 3,600, and 3,626 ci all appear.
- ✗It is tall and narrow with a pocket on only one side, so owners cannot carry trekking poles and a tripod separately.
- ✗Owners flag the thin fabric on the rear divided pockets as a durability risk over time.
- ✗The hardware is plastic and Velcro at a $189 price point, which owners note is loud in the field and collects seeds.
- ✗The whole system's carry comfort is its weakest point — the rigid tubular frame cannot be shaped to your spine, and the one-size hipbelt is the line's most-repeated complaint.

This is Eberlestock's lighter alpine configuration: the Vapor 5000 bag (5,000 ci, about 82 L) on the Modframe, the brand's June 2025 frame. There is no bundle SKU, so $568 is the two parts bought together ($349 frame plus $219 bag), and the pair weighs about 7.7 lb. The frame's integrated load panel holds meat against the back.
