The Rab Spire Pants are fantastic, breathable, and comfortable mountaineering and ice climbing pants.
The Spire pants are super comfortable due to their stretchy Matrix softshell fabric.
Although outdoor gear isn't always designed to be stylish, I like the style and color of the Rab Spire pants.
The pant legs have reinforced patches to protect against crampon spikes.
The Spire pants are incredibly windproof and are perfect for nasty weather.
The gusseted pant legs have zippers to help fit over boots.
The pants have articulated and reinforced knees to stand up to wear and tear.
The Rab Spire Pants are suitable for warmer winter hiking, but are probably too heavy (and definitely overkill) for most weather 3-season hiking.
