Southwest 55 by Hyperlite Mountain Gear

Ships in 1-2 business days | Based in Biddeford, ME | Est. 2010
Hyperlite Mountain Gear's close-quarters pack
On rugged and tight trails, the Southwest 55 is a flexible performer that can adapt and handle the way gear volumes change for weekend, section, or thru-hikes. Ideal when resupply points are less frequent and/or when equipment flexibility is needed. Now made with a new, fully woven Dyneema® 200-denier fabric that offers more durability than ever with the same signature lightweight and 100% waterproof qualities that have made Dyneema a favorite fabric choice. When the extra volume is not in use, the 55’s top can roll down enough to make the overall size of the pack similar to the 40, but that additional space can come in pretty handy when you need it. This pack is comfortable and durable for all types of adventures.
Features:
- Internal Frame: Integrated ¼” foam back panel pad, 2 removable aluminum stays
- Padded Hip Belt- featuring closed cell foam and spacer mesh, provides comfort and support for long hauls
- Made with exclusive Dyneema® Woven Composite 3.9: this fabric provides exceptional abrasion resistance, feels better to touch, and reduces crinkling in cold conditions
- Roll-top closure system with vertical compression straps allows you to adjust the pack's volume, keeping the load compact, stable and protected from weather
- Top Y-strap provides compression and top-of-pack storage for gear
- Two removable, contoured aluminum stays offer support and help distribute the load
- Seams taped on all vertical side seams and behind sewn-on pack features enhance water resistance, keeping your gear protected from the weather
- Sternum strap allows for easy adjustments along shoulder strap daisy chains
- Redesigned shoulder straps feature an adjusted shape for a more natural curve around your neck
- More frequent bartacks provide increased sternum strap adjustment options, allowing for a customized fit
- Removable side compression straps for versatile gear attachment options
- Streamlined hydration system featuring a simple bladder hang loop and repositioned hydroport
- Sewn-through back panel construction creates a curved shape that locks the interior panel in place, providing a more comfortable and durable fit
