I was in Cotswolds Outdoor earlier this week measuring rucksack straps (long story, don’t ask) when I noticed that Grivel Spider in-step crampons were on offer at half price. So only £15 instead £30. I was unable to resist the temptation!
These Spiders are small and light enough (140g inc bag) to keep in the rucksack most of the winter whereas my Kahtoola crampons are big and heavy enough that they are something you decide you may need and take with you. You don’t take them along for fun!
