Hyperlite Mountain Gear Southwest review

The Southwest is Hyperlite's all-terrain roll-top pack, built for on-trail, off-trail and all-season use. The body is Dyneema Woven Composite 3.9, which Hyperlite says is more durable than its heavier Dyneema Composite Hybrid 5.9, and vertical side seams are taped for water resistance. Exterior pockets use solid fabric rather than mesh to avoid snags and protect gear on rocky ground. It comes in 40, 55 and 70 L; the 55 L weighs 30.8 oz in white and carries up to 40 lbs., while the 70 L carries up to 60 lbs. Two removable aluminum stays, a dual density foam hipbelt with zippered pockets and a Top Y-Strap complete the carry. Prices start at $395, and add-ons such as the $25 inside pocket and $35 bottle pocket raise the total. We compared documented features and published prices and did not carry the pack.
