Ibex Meru Hat

Small, warm, snug, and easy-to-stash when you don't need it.

The smooth flatlock seams that join the incredibly soft panels of the Ibex Meru Hat make it a ideal to wear under a helmet in winter. With a snug fit and added nylon and Lycra spandex for stretch, the Meru is the ideal winter cap for your skull when you run, bike, hike, ski, or snowboard. Whether you wear it out to dinner and drinks as a casual après-ski head-warmer or need to take it off during a rigorous activity, simply fold the Meru and stash it into just about any size pocket.

My son's favorite hat

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Originally got it to wear under ski helmet. It fits well, looks great, warm and breathable.
But one day, my kid got a hold of it and now it is his favorite everyday fall/winter hat.

Just what I was looking for. This fits me perfectly and holds the warmth in very well. What pushed this in the five star range for me is the temperature range I can use this in. I've run in 35-60 degrees. I use this beanie for running on colder/cooler days. From what I've run so far I'd say this is ideal for the 40s and 50s, but can go down and up a bit from there without feeling it too much. I was worried that the brand would stick out, but it is very subtle. I don't mind it at all. In fact, the brand is a bit of an asset as it helps me identify the front really easily if I take it off during the run and need to put it back on.

A hat you can run in, the whole run

    This hat is warm and fits great. Perfect for running, touring, late season biking and even under the ski helmet. Breathable and warm but doesn't suffocate. The merino wool is some of the best.

    Great little beenie

    I bought this specifically to wear under my cycling helmet on cold day rides. It works great for that purpose as bike helmets are designed to let a lot of cooling air onto your head and some days you don't want/need that cooling effect. Now I wear it almost all the time as fall and winter are approaching. It's so light and comfortable you don't know its on your head

    Nice fit

      I bought this for my husband and then stole it one day for a cold run. I didn't give it back. It's the perfect thickness. Not thin, not bulky. Fits close to the head on both my husband and I.

      very small, super thin. scratchy

      • Familiarity: I returned this product before using it
      • Fit: Runs small

      is very tight on me and I have a small head. It's also very itchy for merino wool. Feels more like regular wool.

      Great hat

      I used this hat throughout the winter in frigid Wyoming temperatures. The Beanie was warm enough to keep my ears for freezing, but ventilated my heat well enough that my head wasn't a wet mess, Which can be extremely important when it drops into the negatives. The only thing I would change about this hat is to possible make it a little bit longer.

      Superb beanie

      • Fit: True to size

      Bought it for my husband and so far he has been really happy with it. Stretches a bit so if you have a bigger head it would stretch out and fit. Great in between thickness so it's warm but not too warm.

      just what he wanted

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

      This is the perfect beanie! The fit, style, warmth and thickness.

      Great, warm beanie. I have several and this is by far my favorite.

      Quality Skull Cap

        I wear this under my helmet on cold days and it fits under there pretty well.. I have a giro surface-s helmet, and without the cap i can click the tightener twice, with the cap only once.. so it doesn't take up that much space.. its warm and protects against wind.. I would recommend to others..
