For those outdoor junkies who are out backcountry skiing one week mountaineering or backpacking the next the versatile Mountain Hardwear Men's GTX 2.5 Pant is a must have. The lightweight yet durable Gore-Tex® Paclite® 3-layer laminate is waterproof breathable and extremely packable an ideal combination when living out of a backpack. Also the full length side zips allow for easy venting if the rapidly changing mountain conditions switch from rain squall to blazing sun. And these same side zips make short work out of taking the pants off over ski or climbing boots.
