Mr. Roger's was rad, but he didn't spend much time outdoors. Had he been into morning hikes, spring skiing, or walking to the local happy hour, the I/O Bio Merino Men's Signature Hoodigan Pullover Sweatshirt would have been his go-to piece. This versatile garment combines comfortable aspects of hoodies, cardigans and shirts, and wraps you in warm merino wool for total temperature maintenance and breathability. Super soft and stretchy for active pursuits, Mr. Rogers would have dedicated a song to the I/O Bio Merino Signature Hoodigan.

    I was really excited for this one, I've been wanting another merino piece for a long time, I love all my current ones, however this one lacks an essential quality, which is a waistline that stays at your waist. its super comfy and warm and never gets stinky and all the other great merino qualities, but its too short in the torso, and has vertually no elasticity to keep it in place... still havent decided if ill be able to make it work, I wanna give it a fair shot, but it might be going back.

    5'11" 165lbs athletic, long torso.

    Edit: So after giving this guy a fair shot, I ended up deciding to send it back, I just need my shirts/hoodies to go past my waist. Nothing wrong with the material, or construction, just a funky fit, by all means this would be awesome if you have a short torso.

    Great pullover...but

      Great pullover...soft and comfortable and a great warm layer. I am 5'10" 175 with a fairly athletic build and the large fits well with one issue. The sleeves are maybe an inch or two too short. The loop holes for the thumbs work well but they do pull a fair amount. One additional inch would go along way. Overall great piece.

      Mmmm merino wool

        Love this pullover..soft, comfortable, warm. I'm 5'10", 170 and I got the Large which fits well...only complaint is that it is made to fit close to the body which is nice but the sleeves could stand to be an inch or two longer. I am average size and I can just get my thumbs into the loop holes on the sleeve. Overall love it.

        Can't Stop Wearing It

          I just got the navy colored one in a large in the mail last night. I put it on and found no reason to take it off because it fit so well and was so comfortable. I'm 6' 185lbs and find the fit perfect. It's not too tight and not too baggy, but just right.

          I haven't tried it yet, but definitely think I could comfortably put on a medium base layer underneath. It'd fit like a glove! I also like that the cuffs each have a little slit to stick your thumb in so you can keep your hands warm. I wore it in to work today and feel like I'm not wearing anything at all - so light and regulates temperature so well. Oh and the hood fits perfect over my noggin. I have a narrow yet long head (size 7 5/8s for fitted baseball hats) and this thing covers it without any restriction but doesn't impair my peripheral vision.

          One drawback is the care of the garment. I'm a big smartwool fan, but am a little irritated that this has to be handled with more care in the washer and hung to dry. No real biggie since it's wool, so I don't have to wash it as much and it'll dry faster than just about anything else.

          Warm Stylish Functional

            Just got this before the wind started blowing in New York last Saturday night and, I pretty well haven't taken it off since. Great layering piece for cooler weather and even my 16 year old thinks it looks good on her old man. Athletic fit, 90/10 wool/nylon blend for durability. I plan on using it this fall/winter as a ski layer. Cheers.


              I have been using the Hoodigan top as my insulation layer while backcountry snowboarding. I layer with an I/O Bio Euro Tee, which is what I wear alone if warm or with my Soft Shell Jacket if windy or colder and add the Hoodigan if it gets cold or for descent. I had all the above layers on yesterday in Grand Teton National Park, where I was splitboarding up the West Hourglass Couloir on Nez Perce. The Hoodigan was vital to my warmth with the wind whipping and I was stoked to throw the hood on and instantly be warmer.

              Inside, he Hoodigan looks great and fits well. I am rocking an XL and it is long enough in both the waist and arms. I am 6'2" with a long torso. It is my experience that the torso length of I/O Bio products is long, which is great. Nothing worse than having your shirt come untucked during wintery activities, that is unless I pull it out and roll it up and hook it on my avalanche transceiver to cool down a bit. I try to regulate my temp without taking clothing off and putting it on. This entails pushing up sleeves to expose wrists/forearms to cool down, untucking shirt and rolling the entire bottom of the shirt (front and back) up to get my midsection air, taking off the hoodie.

              The softness of I/O Bio Merino can't be overstated. This stuff is extremely soft and comfortable. I am stoked they exist because I like to have functional clothing that looks good while using it in the hills as well as during life in the valley. Another bitchin aspect to I/O Bio merino is the fact that I can wear it in the mountains ALL DAY, sweating profusely at times, and not have it smell! I can go two or maybe three days of use without it needing to be washed.

              Bottom line: Great Hoodie that functions well both in the mountains and on the town.

              I wanted an insulation-layer hoodie. I bought this one partially based on Stephen's review, I trust his experience.

              First thought upon receiving was it's thin, light. Lighter than I'd think for insulation layer.
              First thought upon using was Stephen was spot-on, this thing is perfect for insulation layer.

              Maybe lighter feeling than you'd expect, but super warm. It really warms you well I love this piece.

              Does anyone know the weight of this hoodie?...

              Does anyone know the weight of this hoodie? Also, how bulky would is be in my pack?

              Best I can give is my opinion here.. This is a nice looking pullover. I have a similar size Outdoor Research zip up hoodie, also wool. It weighs aprox. 16oz and rolls up to about the size of two nalgene 32oz bottles. I am just guessing you see pretty close to the same in this pullover, possibly not as bulky though.

              Can anyone who owns this comment on the fit please? I see under tech specs it says "slim" but I have a 39" chest, which puts me in between medium and large. My 30-32ish" waist puts me at medium. Im sure I will be swimming in a large, but I'm not interested in a thermal underwear fit either. Is it an athletic fit or a tight fit is my question I guess. Thanks for any feedback!
