The lightweight polyester stretch-woven fabric of our Simul Alpine Pants moves, breathes and resists weather, while the articulated pattern and gusseted crotch complement the technical cut. The separating zip-fly waist adjusts solely with our sleek, innovative OppoSet™ adjustable waist closure (no more belt loops) for an on-the-go, customized fit. The two front and two thigh pockets (sized to accommodate a field notebook) all close with zippers. A slender lower leg lets you see your feet, and the cuffs tighten with a shock cord and cord lock. Tie-down loops allow you to attach an under-the-heel cord for use with ice boots.


Durable, stretchy and breathable polyester soft-shell fabric with a DWR (durable water repellent) finish

Articulated pattern and gusseted crotch enhance movement and comfort under a harness

Zip fly with OppoSet™ adjustable waist creates a low-bulk, customized fit by simply holding the button while pulling the webbing tail to tighten

Zippered and welted pockets and zippered thigh pockets sit above the knee and below harness leg loops

Narrow lower leg, adjustable single cuff and tie-down loops for compatibility with alpine boots


5.2-oz 100% polyester stretch double weave with a DWR (durable water repellent) finish. Fabric is certified as bluesign® approved

Water Resistant

DWR (durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.

Favorite Hiking Pants
Wore these hiking through chilly misty days with capilene liner pants in Jasper Nat'l Park and Banff. Kept me warm & dry, and allowed me to move easily over some steep terrain. The adjustable waist button was awesome since I slimmed down a bit after 8 days of hiking. Highly recommend!

Excellent Pants!
I just returned from a 12 day trip to Tanzania where we spent 7 days on a hike to summit Mount Kilimanjaro. I wore these pants 6 out of the 7 days. Durable, lightweight, water resistant. Excellent pants and glad I had them with me. I wore them while hiking in the rainforest and they also served as my outer layer on summit day.

I really like these pants
The pants are a nice fit. The smooth stretch fabric gives as it needs to and sheds light rain. Good coverage of backside,plenty long for my long legs,and the tab that draws in the waist at its button closure helps these pants fit better than others I have found. I plan to order another pair in the second color.
