DMM Ski

Frequently Asked Questions

• How do I choose between the DMM Spire and Spire Tech ice axes for ski touring?

  Spire is aimed at general ski touring and alpine walking where light weight and reliable self-arrest are priorities, while Spire Tech has a bent shaft and more aggressive ergonomics for sustained technical steeps and mixed snow/ice. Choose Spire for fast approaches and low-angle travel, and Spire Tech when you expect prolonged front-pointing, steep snow, or technical alpine moves.
• What shaft length, grip, and leash options should I prioritize for ski-touring ice axes?

  For ski touring pick a compact length that allows comfortable self-arrest and fits when skinning—many tour-focused axes are sized shorter than classic mountaineering tools to save weight and avoid interference with skis. Look for ergonomic machined grips (as on Spire Tech) and modular leash options so you can tailor hand fit and minimize snagging while still retaining security on steep terrain.
• What materials and strength ratings make DMM carabiners like the Phantom suited for alpine and glacier travel?

  Phantom biners use alloy bodies for ultralight performance with precise machining and anodized finishes for corrosion resistance, paired with robust gate designs and rope grooves for reliable handling in gloves. They carry CE markings and common alpine strength stamps (example: ~23 kN closed, ~9 kN open, ~7 kN minor axis on Phantom-style hardware) and are manufactured and tested to industry standards (3‑sigma testing noted), balancing low weight with necessary load-bearing capacity.
• How well do DMM drive-in protection tools such as the Terrier work on winter turf and mixed ice?

  Terrier-style drive-in pins are designed to give secure placements in turf, hard snow and some ice where screw placements are impractical; they provide light, repeatable protection for winter approaches and steep snowfields. Their machined construction prioritizes durability and clean edges for driving and removal, but they are best used as part of a mixed protection strategy alongside screws and natural anchors where conditions allow.
• How does the Phantom carabiner compare to other ultralight biners for use with gloves and technical alpine gear?

  The Phantom is engineered to be among the lightest functional biners while retaining a usable gate and rope groove, making it easier to handle with gloves than many minimalist designs that sacrifice ergonomics. Compared to heavier, work-focused biners it trades some bulk for weight savings, but maintains industry-standard strength ratings and precise machining to ensure reliable clipping, racking, and anchor work in alpine settings.
