BLACKYAKMaiwa Backcountry Insulation Pant - Men's

Stay toasty in the alpine.

You're pushing up a particularly difficult alpine route when you suddenly stop to reflect on the journey ahead, looking at your watch to see it's hovering right around zero degrees outside. As you ask you climbing partners about their overall warmth and comfort, it's readily apparent you're the only one that's not shivering-cold in these absolutely frigid conditions. It's no coincidence that you layered up in the toasty-warmth of the BLACKYAK Men's Maiwa Backcountry Insulation Pant before heading for the trailhead, reaping the heat-trapping benefits of G-Loft insulation placed throughout the seat and knee panels.

G-Loft mimics the lofting power of your favorite down insulation pieces, yet it's not susceptible to outside moisture, as its synthetic fibers don't retain excess moisture and clump together like down. This synthetic insulation is highly breathable to regulate your body temperature when you're moving quickly in the alpine, as well as packing down efficiently and remaining resilient through numerous washings. These characteristics make it a near-perfect insulator for the extremes of alpine mountaineering and backcountry ski touring.

Very warm

  • Fit: True to size

I got these to be worn on the colder days in Utah and they are great. The added insulation is very much appreciated on chair lift rides. These are a good bit thicker than my icebreaker bottoms an as such, I treat these as more of a midlayer than a baselayer. If I skied Vermont, I wouldn't hesitate to pick these up.

I would give these 5 stars if the pant use a thinner Merino throughout with added insulation in the baffles. But, these aren't far off from perfect

Unanswered Question

Greetings from Greece!
1.would this fit under a "slim" shell? or should I have an oversized shell to be sure?
2. Is it OK for "normal" weather backcountry skiing or too hot for that and only suitable for supercold days? (is there an upper temperature limit for use under a shel?)

Down Jacket for your Legs!!

  • Familiarity: I've used it several times

It's the perfect addition to a killer pair of shell pants. Why didn't I think of this years ago! I know what your thinking, "these will be super hot". Well with the placement of G Loft in certain areas and Power Stretch throughout the rest... it's a perfect balance!
