Men's Diomede Merino Wool Snorkel Hoody

Seriously I have every weight icebreaker long sleeve ever manufactured….. same with Duckworth Smartwool and mons royale. The duckworth maverick series WAS my favorite baselayer until this beauty arrived a few years ago. I purchased my first diomede hoody from backcountry.com and I was shocked how it performed. This baselayer is like a spider web that you throw over your dome. When I opened the XL I said “no way is this going to fit me “ no way Jose”. I am 6 feet 235 46r chest 36-38 waist and amazingly it fit. I want my baselayer to be semi snug/tight. This baselayer has an incredible amount of stretch. Seems like the more it’s stretched the more it contours to your whole body. Unfortunately I am always cold 🥶. Had some car trouble on a 5 degree day with just this diomede hoody and a thin Mammut jacket. I was expecting to be frozen by the time the flatbed finally loaded my vehicle. A good 25-40 minutes in 5 degree weather and I’m not saying I was overheating but i definitely was not freezing. The price is obviously not cheap and I totally understand some might not be able to make this work for their budget. I was lucky enough to get my first one at sale process from backcountry but do not expect to get the XL on sale anytime soon in the future. I have never seen this hoody for sale other than beringia and backcountry. Oh and let’s talk about the odor control. I rock this thing for months in a row daily from sept/oct until April. I wear it underneath a slim fitted wool vest when golfing in April (Massachusetts) and it performs amazing. The criss cross weave of the fabric will lock in some heat while allowing the moisture/heat to escape so u do not feel moist AT ALL. I have brutalized my diomede for two years and I have 1 small tiny hole on the chin aspect of the Ninja hoody and that was from being too forceful trying to find it under some other layers when I was ice fishing in single degree temperatures. I purchased 2 of this new restock December 2025. I wear the old one daily still and I wear the brand new one when going out for the night. I needed an extra one probably because of some pad 😆 but honestly it’s more from anxiety that the xl will sell out (like it did). Now as far as care for this item. I hand wash in cold water and once everything is rinsed I just twist all the water out of it and stretch the shirt as much as I can. Hang it over anything and it’s perfect! Never ever ever ever dry this thing. Even on low heat. The process from hand washing to drying is maybe 2-3 hours. Throw a fan on it and it’s probably 1 hour to dry. I have the non hoody and I like it but I will only buy the ninja hoody to cover my 52 year old bald dome. From Massachusetts…”this thing is wicked killa” just buy it and be enthralled like the rest of us …BBB

This is hands down the most comfortable base layer I’ve ever worn. It’s so cozy that I keep it on for hours even after a full day of skiing. The longer fit is perfect, and the fabric feels completely unique, unlike any other base layer I’ve tried. I can’t recommend it enough.

Great stitch which makes a great fit. Hoody for the win

Super comfy next to skin and so warm. I loved the top and so I bought the bottoms as well.

Weather variance in the Valhallas in late March and April is a thing. Shedding layers on the up track only goes as far as your base layer and while I did manage to sweat my ass off, the Diomede Snorkel hoody wicked it and dried quickly. The snorkel is magic when you rise above the trees, the wind kicks up and you’re able to keep the sideways flying graupel from getting into your ears. The bonus is that you can wear this for four straight days or more and it doesn’t get stinky. A quick wash with short, low heat dry cycle will put it back into perfect form.
