    Fly up the trail and down the slope in your Helly Hansen Fly Pant base layer.

    Wear the Helly Hansen Men's Fly Pant long underwear for aerobic activities in cool weather. These bottoms wick moisture and dry quickly, so you can sweat your way up a mountain or rush down a ski run and not feel clammy or chilled. They're also antimicrobial, which means they won't stink at the end of the day.

    Not stretchy enough

    • Familiarity: I returned this product before using it
    • Fit: Runs small
    • Size Bought: M
    • Height: 5'7"
    • Weight: 142lbs

    I was expecting more stretch. The legs had a strange constricting quality which I did not enjoy, especially at the knees, where my motion felt hindered. Maybe the next size larger would have worked, if the waist wasn't too big, but I didn't want to take that chance. Full disclaimer: I am a woman, but almost all of my comfortable pants are mens'.

    When it says it runs small, they mean it

    • Fit: Runs small

    If you normally wear a medium, get a large. If you are on the larger side of medium, get the extra large.

    The material, waistband, and workmanship all look pretty good though. It also has subtle trade markings!

    Great base layer.

    My husband uses these during the winter as a base layer when he is working outdoors. Comfortable and warm.
    Initially, I ordered a small. Returned, and reordered size medium.
    His waist size is 32.


    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    Excellent fit, almost as good as the Patagonia. Can't wait to try them at the mountain this winter.

    Use in lots of weather

    I used these a lot on ski touring days last season under shell pants when the weather wasn't super cold. Lately I've been using them on mountain runs in the morning when the air is still cold and crisp. They breath well, insulate well, and don't restrict at all. My latest outing with them was a half-marathon in the mountains that started at dawn. Temps were below freezing at the start and near 60 degrees at the end. If you have more questions about any of the gear feel free to contact me directly (google my name and my contact info is easy to fine).

    Size runs smalls

    • Height: 5'5"
    • Weight: 155lbs

    I normally wear a small and I bout an Oakley base layer. the Oakley is a size small, and it fits perfectly. but this HH is seriously tight, so tight I could barley pull the baselayer up. So if you get this, get a size bigger.

    Great base layer, nothing unexpected

    • Familiarity: I've put it through the wringer

    Size is true to fit (I usually take a medium in pants - 32-34" waist - and these mediums were a perfect fit), comfortable material, no bunching, and perfect weight to keep one warm on moderately cold days.....they are listed as "lightweight" layer, so those looking for some serious warmth may want to go heavy-weight......these work great for me though - I'm on season 3 or boarding with them as my go-to base, and I've never complained about being cold.

    Overall: great product, fits true, price is well worth it. Buy 'em.

    lasted through mad trials

    • Familiarity: I've put it through the wringer

    For a basic base layer, I found these to be the longest lasting. I work as a hotel valet in Alaska. Running in the cold almost every winter day has put a lot of gear to the test and I have to say for warmth level these have passed the friction test. Burned through multiple patagonia cap 1 base layers. Not feeling the diff in warmth protection I'd recommend these over the patagonia. All my other base layers have worn holes in the crotch area where as my hellys from years ago look good as new.

    Nice set of pins

      Bought these to go with the Helly Hansen Dry Stripe Crew Top to form my thermal set for winter in Everest Basecamp region. Bottoms are nice and comfortable and appear strong. Nice and spacey for tall guys too.

      Very Nice Fit

        I love everything about the HH Fly Pants. For me the fit is spot on, the fabric is super quick to dry, and they do better than average with stink. The fabric runs/snags easily so keep away from sharp objects: Fingernails, velcro, etc., or you'll end up with a nice snag in your baselayer. I wouldn't hesitate to buy again.

        I'm a bit confused.
        In the size chart, which is the measurement for Medium size? Because the shirt will have the measurements for the 'letter' size, but not the pants.

        Future thanks for the help.

        Best Answer

        The size chart for "lettered" sizes also contains measurements for waist, hip, and inseam. Use those for this item. Some H/H pants use numbered sizes, which would use the other size chart, but these ones don't.

        what temp range would should I use these...

        what temp range would should I use these for?

        are they more like a tshirt weight or a little thicker like thin fleece pants?

        I currently use some older Hot Chillys fleece type tights/long johns with a non insulated ski shell which has served me well.

        I will be in CO skiing this Feb which is what I will use these for.
