Specifications
| Price (US) | $399 US price $399 for the Southwest 55. AdventureAlan's "Southwest 55 Review 2025 Version" lists "Price: $399" alongside "Weight: 30.8" (oz), matching HMG's own 55L spec (30.8 oz | 874 g); Switchback Travel's Southwest 55 review likewise lists "Price: $399". HMG's official product page shows "$395.00" but renders the 40L default variant, so the model-specific $399 from the two 2025 reviews is used for the 55L. |

Source: hyperlitemountaingear.com (read 2026-07-11) STALE · 2026-07-11 · corroborated by adventurealan.com (read 2026-07-11). HMG's official Southwest product page (source) lists the 55-liter variant's specs distinctly from the 40L/70L siblings — Volume 55L, White 30.8 oz | 874 g (size medium), Load Capacity "Up to 40 lbs", roll-top closure, two removable aluminum stays, and a main body of "fully woven Dyneema 200-denier fabric" — confirming this is the exact current 55L model. AdventureAlan's dated "2025 Version" review (corroboration) independently confirms the current 100% woven Dyneema (200D) Southwest 55 at "Price: $399" with matching "Weight: 30.8" oz, a dual aluminum stay frame, velcro roll-top, an internal hydration sleeve, and an explicitly non-aerated flat Dyneema back panel; Switchback Travel likewise lists "$399" and 200D for the Southwest 55. Price $399 comes from these two model-specific 2025 reviews because HMG's page renders the 40L default variant's $395.00 rather than a distinct 55L figure.
