The Southwest from Hyperlite Mountain Gear is their most durable pack, built with new Dyneema Woven Composite 3.9 fabric, offering lightweight yet exceptional durability and abrasion resistance. Designed to withstand rocky and abrasive terrains, the Southwest is a versatile, adaptable, and reliable choice for any adventure.
The pack's roll-top closure system allows you to adjust its volume for different trip lengths, keeping the load compact, stable, and protected from the weather. Its exterior pockets are deep and designed for better access to gear like water bottles and ice axes, making it easier to pack and retrieve items.
The Southwest series features a redesigned back panel for enhanced comfort and better weight distribution, along with a dual-density foam hip belt for support on long hikes. Whether you're tackling the Australian Alps Walking Track, the Larapinta Trail, or going for a quick overnight trip, the Southwest is a rugged pack built to perform under all conditions.
Your torso length, not your height, determines your pack size. We recommend the following to determine yours:
1. Tilt your head slightly forward to locate the bony bump at the base of your neck. (This is your 7th cervical (or C7) vertebra).
2. Using a flexible tape measure, have someone measure starting at that spot and running down along the curve of your spine.
3. Place your hands on your hips so you can feel your iliac crest, which serves as the “shelf” of your pelvic girdle. (It’s the first hard thing you feel when you run your fingers down from the sides of your ribcage.) Position your hands so your thumbs are reaching behind you.
4. Have your friend finish measuring at the point where the tape crosses an imaginary line drawn between your thumbs. This distance is your torso length.
5. If your measurement falls right in between sizes (for example, if you have a 17.0” torso, so you are right on the line between a Small and a Medium), we suggest you choose the larger torso size.

| Size | Torso |
|---|---|
| Extra Small | < 15" |
| Small | 15.0” - 17.0” |
| Medium | 17.0” - 19.0” |
| Large | 19.0” - 21.0” |
| Tall | 21.0”+ |
