Question 9

Will the pants fit over mountaineer boots? ie ice climbing

River · Accepted Answer

Hello there, the Gamma MX Pants are versatile and designed with winter activities in mind. They can generally fit over mountaineering boots, though it does depend on how bulky the boots are around the ankle. The stretch and adjustable features in the pant help accommodate most boots, but for especially wide or heavily padded boots, you might need to double-check the fit.
