Customer Reviews Arc'teryx Rho Heavyweight Zip Neck

This has become my single most important winter and fall layer for everything from casual day hikes to overnight alpine expeditions. I use it over a wool base and that provides more than enough warmth for active times with temperatures 20-40F. I have two that are a few years old and going strong after taking lots of abuse. Cannot recommend this enough.

This top fits absolutely perfectly. It is the perfect balance of weight, fit, comfort and dress. The colour is stunning

Exceptionally well made, comfortable all day when active but remaining warm when static. So good I have four!

Very soft and warm. Also very stylish if you have an awesome bod like mine. It's as I imagined.

I brought this 2 weeks ago, was expecting it to more of mid layer with T shirt underneath, As i own the Rhio Lt so was wanting to wear this over the top, but clearly a thick base layer, as you will struggle to wear anything underneath, but that saying, feels great against the skin. Needs to be cold or you will overheat in this top, I absolutely love the cut, as i'm small, but stocky build, but some may not like the tight fit and find a bit restrictive. Goes great with an arcteryx Gillet. Its defo a 5 stars from me and ill be buying a few in different colours to help with harsh brecon beacons weather

Great quality and exactly what I was looking for. Fits perfectly.

A little about me 1.75m (5ft 9in) tall and weigh 73kg (161lb). My chest measures 108cm (42.5in) and waist 84cm (33in) with an athletic build normally a size medium in Arc'. I got a medium in the Rho Heavyweight and it fits very well indeed. Close enough to wear as a baselayer if needed but loose enough for me to wear it for my preference as a mid-layer fleece over a Phase long-sleeve base. The directional wicking and performance stretch of Power Stretch is just excellent for the wet conditions prevalent in the UK. In winter I can wear this alone with a shell on walk-ins or together with a Proton FL in colder conditions. I have two colourways - Multiverse and Phenom - they look cool as part of a layering system!

A fine baselayer, and you can even fit a thinner layer underneath. The zip is smooth

I bought this a few weeks ago and it was money well spent! Bought it just before a ski trip, and it did not let me down. It is a super warm and comfy fleece, and the stretchy fabric allows for great mobility. Highly recommend!

Fantastic heavy weight base layer that can be worn as a standalone. Wore mine while trekking to the Refuge at Illiniza Norte in Ecuador as we had nice weather. Once at the refuge the weather turned a bit colder and windy so put on my Alpja SV and was good to climb for the summit. Excellent piece of kit.. I'm going to get another colour!

I've been wearing this for about three months now, and it's quickly become one of my favorite layers to have on in a variety of conditions. It isn't baggy which makes it easy to add layers on over it, but I can still comfortably fit a wool base layer on underneath for cold days. I've liked it most as a standalone layer while bouldering since I can be active in it without being too hot, and easily put on a warmer layer over if I'll be staying still for longer. On a November climbing trip to Bishop, CA, I ended up wearing this every day while sleeping, climbing, and hiking. While I haven't torn the material on rock, if I was spending a day scratching against rocks I'd probably wear a different outer layer since this fleece might not stand up to extended use on granite. Overall, I've been very happy with this Rho Heavyweight and have been surprised with how often I reach for it on days outside.

Warm and light weight. Perfect for hiking or an under layer for skiing.

I bought this one in Black Sapphire, after giving up waiting for the Kyanite jacket to get restocked (come on folks get that supply-chain in order). I am very pleased with the quality, cut and material of the Rho. It's the material that makes this top incredible. Polartec power stretch feels so good that it doesn't really feel like you are wearing a top rather it's more like you are coated in a layer of soft fleece that moves seamlessly with the flow of the body (sounds like ad copy but only way I can describe it). As a result, there is minimal need to use too much articulation in the tailoring (think Delta Jacket which is very cool). I sized up to an XL so I have more of a leaner look rather than looking like a "gym-bro" with a size L. Couple comments to close, if Arc made a Delta Jacket with all the panels and articulation (and pockets) in this material it would absolutely crush the fleece jacket segment. Lastly, I feel this top is a bit of a hidden gem tucked away in the base layer aisle. If this was in the fleece section (and had regular sizing) it would be perpetually sold out like jacket.

Great fabric for intended outdoor use on a ski hill. Went by the sizing guide for 6'3", 210 lbs and arm length, but a large was too small. Returning and getting an XL.

The material is nice and worth the price. I purchased all the colors and love them.

I've had this a year now and it's my favorite piece. I wear it as a top with jeans it's so comfortable and looks great. I also wear it hiking. I recommend wearing a very light merino t- shirt underneath it protects the garment from underarm perspiration. Please bring back the Multiverse color ( Purple). That's the reason I bought it in the first place.

Super comfortable feel. Though the product is meant to be "close to the skin" as a base layer, I opted to go up an extra size so that it would also be used as a stand alone mid layer

It's so warm, but not too thick to the point at which it is restricting. It is super flexible/form-fitting, but in the right places.

I love it so much I bought another one. Quite a snug fit but really comfortable and very warm.

I bought this 6 weeks ago and can recommend as a base layer. Slim fitting, very warm and feels robust. Fits true to size

I bought this for my brother since he's always cold. These baselayers are the best. Great for extremely cold areas and you can still dump heat by unzipping. Love polartec. Looks great even after more than 2 dozen washes.

this is my favourite winter base layer layer. Great fit and excellent thermal properties.

I'm 6'3" and 215 with a slim tending toward athletic build and I love the fit of the large. It offers me full range of movement in a variety of activities while providing warmth and an attractive garment.

Really comfortable and a essential for any skiers!

Got this for Christmas, and you can immediately feel the quality. It is so warm! I'm a ICU nurse and I wear this in the unit and I am never cold. I will be purchasing other colors. My only con is the sleeves are little long for a long, but I can deal with. PLEASE PLEASE make this in a crewneck version. This material is great! I'd love to wear it under scrubs without the added turtleneck.
