What this page can tell you is measured: 60g, $35, and how both sit against every other top tube & feed bags product we track.

How the Outpost Top Tube Bag compares
Against the bags people cross-shop it with, measured rather than reviewed — including how many real frames each one fits.
How it compares
Against the 13 top tube & feed bags we hold published specs for.

At $35 it undercuts 12 of 12 of them, against a median of $65. That works out at $58 per 100g — above the $56 median for top tube & feed bags.
Weight and price come from published specifications. Cost per 100g is a blunt measure — it rewards light gear and says nothing about durability or whether the thing works — so treat it as one input, not a verdict.
