Customer Reviews Arc'teryx Ionia Merino Wool Hoody

The Ionia line-up is sneeeeeaky versatile! The hoody is my go-to as a Spring/Summer cover anytime I face changing conditions and cooler temps. It is lightweight & breathable enough that I can use it as a sun cover in warmer temps, but also adds the perfect amount of warmth when the weather shifts to cooler temps. It is also the first thing I grab when I'm looking for a lighter alternative to my Rho Merino base layer in the Winter. Has been through multiple washes & adventures and is still going strong!

Really comfortable, excellent fit. Seems to be quite durable- fabric seems better than other brands producing wool base layers. Went with L- 6'4" 195 lbs fits well snug but not too tight. Would definitely recommend and will likely purchase another

Own two of these and they are The Bomb! Comfortable stand-alone or as a base layer. Heat-regulating from 35 to 75 degrees Fahrenheit. Wore mine recently on continuous flights from Denver to Argentina and back and was never too hot or too cold while on planes. Can be worn repeatedly even for longer trail runs without stinking.

Slim fit, long sleeves and hood is perfect for hiking while providing for sun protection for 3 season use. Quick dry and no stink makes it also great for multi day use when traveling.

Excellent fabric and a compelling design. It is very comfortable and very warm for a light garment. It runs small--the medium is very form fitting on me.

Wore this piece as a base layer for 5 days straight during a running/camping trip. literally didn't take it off, I even wore it to sleep. Didn't chafe, didn't smell, kept me warm even when it was sweaty & wet

I wore this as a base layer for a 7 day running adventure. I took it off once or twice, it did not smell, did not chafe me and kept me warm even if it was wet/sweaty

Fit perfectly, multi functional and can be used for casual occasions.

Really good layer for rock climbing in the cooler temps...it's light, very comfy, not restricting, warm around the neck with the hood and long enough to not slip out under your harness when climbing

Merino blend is very comfortable on the skin, it makes a lot if difference on cold mornings compared to a merino t-shirt, especially when using a three layers approach (with Atom and Gamma MX): i found i can tolerate 20F without a bliss.Let's see if the seams will last, but i'm rater quite happy with it!

The Ionia Merino Wool Hoody has quickly become a favorite. The merino wool feels incredibly soft and natural against the skinlight yet cozy, with a warmth that adapts perfectly to cooler days. It's my go-to for casual summer evenings, trail running, and hiking when I need something breathable that also provides protection from the sun. Not only is it perfect for casual outings, but it's also suitable for a variety of activities. I opted for a size up from my usual, even though it's true to size, to give it a looser fit, which improves breathability. I also love taking it on flights, as it provides the right warmth and comfort I need during travel. The thinness and temperature regulation of the material make it ideal for different conditions. While it's fantastic for many uses, I noticed some wear from my backpack after just a few hikes, which I've never experienced with polyester or cotton blends. Now, I avoid it for hikes with a pack to preserve the fabric's integrity. Even with this precaution, it's a standout piece that I love wearing, and I even got the crew neck version because I appreciate the material, cut, and style so much. The hood provides excellent additional protection for my neck and head, and on cooler hikes, it makes an excellent base layer. Despite some limitations, it's definitely one of my favorite Arc'teryx products.

Excellent fit, great at temperature regulation, comfortable. Perfect hoodie.

This is my go to hiking shirt, especially on days where it's a little cooler. The trim fit helps wick moisture away and the wool blend is so comfy next to the skin. I have worn this shirt now for hundreds of miles on trail and have no signs of wear in the shoulders or back. It has really impressed me how well it's held up. I've been hesitant to use it rock climbing, as I am not sure if it would hold up with abrasion on the rock. Definitely pricer for a hiking shirt, but has held up really well and would say it was worth investing in. Overall I am very happy with this product and could see myself picking up another once this one gets too many pin hole burns and abuse, especially if they ever make one that comes in Bordeaux.

I am a business traveler and am on planes alot. I Love the wool for heat management/ moisture. I also use the hood as it keeps my neck warm with the air blasting on it. The hood is also long enough that I can pull it down to block out my face to make sleeping easier. I have four of these and I have been using them all year

Outstanding light base or mid layer. Sometimes you find a piece of clothing that excels in versatility, durability and function. The Iona hoody is such a product. Ski touring, climbing or biking it checks all the boxes. As a bonus the merino material is excellent at odor management. Well done Arc'teryx.

This quickly became my go to piece of kit. I have been using this for a base layer winter camping and as a stand alone on chilly trail runs. The hood sits nicely when not in use but has a great fit for a base layer, close enough to keep the heat in but not to tight to be restrictive. The merino wool stays warm when damp from sweat or the elements. I find myself wondering what I was doing before this layer.

bought for PCT hike, really comfortable and cutting is really nice. fits my body. warm breathable , highly recommend.

Super comfortable and very warm. The hood, when down, acts as a neck gaiter to hold in body heat.

This hoody is great. Feels super nice on skin and the hood is a great fit, so you can easily wear a hat on top of it

Very Soft. My family loves the Fika Color!! I'm 6'1" & the XL is sweet!!

Material is very soft, fit is as expected, overall very pleased with this shirt.

Soft feeling great fitting true to size. Worn it multiple times and it is odor free. Arcteryx makes great clothes

This is one of the most comfortable wool shirts I've ever had! It's soft and lightweight, it's warm enough for activity in shoulder seasons or cool mornings/evenings in summer. Could even be a baselayer for colder weather. Works decent for travel too. So comfortable I also wear it all the time around the house and for casual wear in regular life. It's a great option for hiking in cooler, shoulder season weather as it's warmer but not too warm. It does have more of a tighter, athletic fit, mostly in the arms so just keep that in mind depending on what you want to use it for. So incredibly soft and comfortable though that I bought a second within a couple months of owning my first and I now have 3 of these things. Absolutely love them!

I bought this for myself, I am female, and the xs size in men's size s perfect. Love the colour!

Material is comfy, fits tight with stretch, warm yet breaths well. Please Arc don't get rid of this design any time soon!!
