Look for wide-mouth designs for easier access and cleaning, with silicone seals that maintain an airtight environment regardless of altitude changes.

5. Ultralight Hanging Systems: Traditional Protection Methods

Ultralight hanging systems remain one of the most reliable and weight-efficient food storage solutions for mountaineering expeditions in non-bear country. These traditional methods combine simplicity with effectiveness while adding minimal weight to your pack.

Proper Hanging Techniques for Different Terrains

Mastering the PCT (Pacific Crest Trail) hanging method is essential for effective food protection in forested areas. Hang your food bag at least 12 feet above ground and 6 feet away from the trunk to prevent wildlife access. In alpine environments with sparse trees, use rock crevices or climbing protection as anchor points. For glacier expeditions, utilize ice screws or deadman anchors when traditional hanging spots aren’t available.

Best Cordage and Bag Combinations

Select 50-foot sections of 2mm spectra cord for optimal strength-to-weight ratio, weighing just 1.2 ounces yet supporting 275+ pounds. Pair this with silnylon food bags featuring waterproof roll-top closures for weather protection. The Sea to Summit Ultra-Sil Dry Sack (13L size) weighs only 1.3 ounces while the Hyperlite Mountain Gear Food Bag offers 10L capacity at 1.6 ounces.
