- Familiarity: I returned this product before using it
I'm returning this item unused before I poke a hole in my backpack or rip my down jacket. If your crampons have toe spikes, this brilliant design will allow the tips to penetrate the mesh bottom. On top of that, the sack seems far too short to fit most crampons. I could see it being good for phones, cameras and GPS's but not technical crampons.
