Max hangs in training? Hiking in to your proj and no good warm ups around? Alpine rock and first pitch is 5.hard? Don't want to blow up your precious finger tendons? Then get this donut but instead of eating it like Homer Simpson, squeeze it until your ready to send. It doesen't weigh much in your pack unless your doing a cutting edge ascent in the gnar. Or a wuss, IDK. Either way the green one has a spot in my bag.
