Quick answer: Those cords and straps each do one job. Compression straps tighten the load so it does not shift. Load lifters pull the top of the pack toward your shoulders at about 45 degrees. Daisy chains, tool loops and lash points hold trekking poles, tent poles, an ice axe or a pad outside. The sternum strap steadies the pack, and the hipbelt carries most of the weight.
New packs look like a tangle of webbing. Once you know the six types, the tangle makes sense.
This guide names each strap and what REI says it is for.

The Straps
| Strap | Job, per REI |
|---|---|
| Hipbelt | Carries 80 percent or more of the load |
| Shoulder straps | Wrap closely without carrying significant weight |
| Load lifters | Pull the pack closer to your body; ideal angle about 45 degrees |
| Sternum strap | Connects shoulder straps for stability on uneven terrain |
| Compression straps | Streamline the load and keep it from shifting |
| Tool loops, daisy chains, lash points, gear loops | Attach trekking poles, ice axe, crampons, pad or tent poles |
The Elastic Cords
Bungee cords on the front panel hold a jacket or wet layer so it can dry. Some packs have cord that tightens a stretch front pocket. These are for light, bulky items, not weight.
Using Them in Order
- Pack and tighten the compression straps.
- Put the pack on, set the hipbelt on the hip bones, then the shoulder straps.
- Snug the load lifters, then clip the sternum strap about 1 inch below the collarbones.
- Lash outside gear last, and keep it limited; REI warns it snags and scrapes.
Honest Limits
Strap names vary by brand, and ultralight packs omit some of them. Check your pack manual for anything unusual.
