Off-Fit Pullover: Comfort Inside, Issues Out
I picked up the Arc'teryx Delta Half-Zip Pullover for cooler evenings outdoors or as a cozy layer after runs and hikes, based on my positive experiences with the brand's gear in the past. Unfortunately, trying it on right out of the box revealed it wasn't a match for me. The fit felt disproportionate overall: more fabric in the back than the front due to the side stitching, leading to bunching in the rear when standing straight and an odd stretch across the chest despite matching the size of other Arc'teryx pullovers I've owned. The breast pocket added to the awkwardness, causing the front to fold strangely when unzipped, especially with slim items like a wallet or chapstick inside—it disrupted the drape and felt unnecessary for such a streamlined design. Sleeves were another letdown, landing about 1.5 inches above my watch on the wrists, which made them feel too short for comfortable coverage. On the positive side, the interior fleece is as soft and comfortable as expected from the brand, providing that signature coziness against the skin. Pros: Soft, comfortable interior fabric; lightweight for layering. Cons: Uneven fabric distribution creates bunching in the back and stretching in the front; breast pocket leads to odd folding and poor integration; sleeves run short on the wrists, limiting reach and coverage. While the core material holds promise, the overall execution fell short of what I've come to expect, making it hard to envision regular use. I'd suggest it only for those who prioritize interior comfort over precise tailoring, but I wouldn't recommend it to a friend seeking reliable post-activity wear.
Great fleece, for layering or as a stand-alone
Bought this from another reviewer’s recommendation for trail running. The problem with this is, that it looks so sharp and feels perfect for every day usage, so I actually use it at the office and almost every day at home as well (daybreak color has almost same colored pocket, which helps). I run really warm always, so this not being so warm actually works perfect for me. If you run cold, I would maybe reconsider buying this (unless to buy it for spring/autumn as a layering, or for high output exercise).
A favourite no more.
The Delta 1/2 was one of my favourite fleece layers for many years, unfortunately my old one finally succumbed to years of abuse so I replaced it with the new incarnation. The similarities pretty much end with the name. The new fit is baggier than the last and the material used is far inferior to the polartec fabric of the previous. The pocket on the front makes no sense for rock climbing, the shoulder pocket was much more useful. I've searched high and low online for the old style but it seems it can't be found. Here's to hoping the previous formulation returns in future seasons.
Hello there, thank you for sharing your experience with the new Delta 1/2 Zip Neck. We're sorry to hear that the updated design didn't meet your expectations, especially after years of enjoying the previous version. Your feedback on the fit, fabric, and pocket placement is invaluable, particularly regarding its use for rock climbing. We'll make sure your comments are passed along to our design team as we continually strive to improve our products.
As warm as a newspaper
As warm as a newspaper. Very thin fabric, so delicate it looks you can make a hole in it with your finger. The older Delta was nice and warm but this is rather a cooling jacket not something to keep you warm. But I get a feeling I would be warmer wearing nothing. The photos of the item are misleading, they create an impression the jacket is something in between RHO LT and Heavy. But its 50% lighter and thinner than RHO LT and should be priced accordingly.
Hi there. Thanks for sharing your feedback on the Delta 1/2 Zip Neck. We are sorry to hear that you are disappointed with its warmth and fabric and that it did not suit your needs. We will pass your comments to our team.
Great layering piece
Used it for trail running and as a base layer for skiing. Obviously the zipper gets cold on the skin, but the quarter zip helps dump heat in variable output activities. The material has held up, and shows no sign of beginning to stink despite >50 days using it. Tend to run hot, so I've used it as a base layer for -10 to 0 degrees on runs, and put another layer underneath/on top depending on conditions if it gets colder.
Perfect for higher output activity
No experience with the older Deltas but I’m loving my 2024 Delta 1/2 zip as a standalone on runs below 50F. Definitely better for higher output activity like running, so depending on conditions I wouldn’t expect it to keep me toasty for lower output activities or sitting around. Currently dabbling with more synthetics after a lifetime of wool - with that said no complaints about the new fabric or overall comfort.
What you expect from Arc
High quality material at a premium which shouldn’t surprise anyone. Great fit and style for me (5’8 and 145 lbs). Somewhere between a baselayer and midlayer but I expect it to perform well as an activewear piece and hold up well over time. Definitely thicker than the cormac half zip I picked up a few years ago. Took off a star for the price but probably would buy again
great sweatshirt
very nice sweatshirt, I use it for walking around the city and for trips to the mountains as a second layer, although I thought it would be thicker and a bit warmer. The pocket on the chest is a bit for decoration, it is a bit too high, and the iPhone fits into it on the butt and it is uncomfortable with it inside. Overall, I like the sweatshirt - I recommend it.
One of my new faves
I’m wearing this now. I’ve worn it basically every day since I got it. It’s great. I like it because it is so versatile. It can be used for workouts, or unpretentiously with jeans and a t shirt, or ostensibly for rock climbing because you’re wearing Arc’teryx. It blends in in outdoor or urban settings. It looks good. It’s comfortable. What else is there to say.
I ordered a size smaller so it fit snug and tucked
I’ll wear this fleece pull-on for a number of activities. First, for every day activities, and outdoor sports, skiing, fishing, hunting, hiking and running. Since this garment was advertised as a fleece I thought it would fuzzy. That’s the only reason I rated it 4 stars, but I’m happy anyway. I’ll purchase your items in the future.
