UHMWPE-sheathed shock cord with a natural rubber core — the same system that ships on the 2026 Mochilla 30. A direct upgrade for any pack using a front elastic net.

UHMWPE is an ultra-high molecular weight polyethylene — the dominant fiber in competitive sailing lines, applied in a technical shock cord by TUFA. Compared to standard nylon shock cord, UHMWPE is:

• Lighter weight (~50%)
• More cut & abrasion resistant
• Lower friction through hardware
• Superior elasticity and rebound
• Hydrophobic sheath
• UV resistant
• Improved performance in cold environments

By the Foot — Custom cut to your requirements, can add to Kit cut length by request.

Kit with Hardware — 6 ft of UHMWPE shock cord plus 2 aluminum ice tool toggles, 2 front net adjustment clips, and 2 speed hooks for ice tool shafts or trekking poles.

Fits the Arc'teryx Alpha, Hyperlite Mountain Gear Vertex, older Mochilla models, and any other pack with a front elastic net. Cord can be cut to length.

Shock cord made in Austria.
