I absolutely love the fit of this hoody for 24/25, it is flattering (skimming my torso without catching anywhere) and so comfortable to wear. The neck gaiter and hood are great. I am going to buy a second one so that I always have one ready to wear! I originally bought the Rho LT crew neck 24/25 but I really hate wearing it due to the awkward fit - I have to keep yanking at it as it rides up constantly (I had to return my usual size small due to the 24/25 unfortunate style fit change and got the medium instead) - I no longer wear it, what a waste of money. (love the 23/24 version though)
I really like this product from. Comfortable and it has a nice fitting. Great for walks on a chilly day , I used it at hike day and it wicks sweat away.
This is a great layer for touring. I run cold and this layer is perfect for keeping me warm on the uptrack while still being breathable enough to not sweat. If there is wind, the hood and balaclava combo is perfect, and it makes it quick for me to pop my helmet on overtop for the downhill. As a bonus, this is a great layer for winter runs! Overall, I love this hoody.
This base layer is so good for so many reasons. It dries quickly after the approach or the skin uphill and keeps me warm when I’m belaying or transitioning. The hair tie hole in the back of the hood is *chef’s kiss* so good. The buff in the front keeps my face out of the cold and doesn’t get too stuffy. Just all in all a great base layer
I have 2 of these hoodies, and I don't think I'll buy a different style ever again. The built in balaclava stays in place, locks in warmth where I typically lose it, and the fleece is buttery soft (to quote a certain legging manufacturer). Great colorways, runs true to size, and holds up to years of use with minimal pilling.
This is a must-have piece for me whenever I go snowboarding. It's incredibly breathable, keeping me warm without overheating or sweating. I also love how the hood doubles as a balaclava, so I don't need to carry an extra piece of gear. Plus, it looks great as everyday wear, making it a versatile addition to my wardrobe!
Do I have to take it off? Buttery soft, perfect length, great hood neck gaiter combo My new favorite layer for all winter activities. Hood fits great under my helmet so I don’t need to wear anything extra on the mountain. Can wear the hood over or under a baseball style hat making morning dog walks enjoyable.
Basically live in this all winter. It’s by far my favourite. Soft and warm, but breathable. I wear this no matter what temperature it is. Doubles as an under helmet hat and neck warmer. It’s not tight in the neck, which I love. Prepare to forget what it feels like to get snow down the back of your neck.
I love this shirt! It’s breathable but also keeps me warm for my winter runs. I also love how I don’t need to find a hat. The material is so soft and comfortable. For some reason I don’t sweat much in this which I love because I won’t be cold and wet.
LOVE THIS! Best cold weather running piece that I own. Winter running gamechanger! Warm and cozy, yet soft and light. I was concerned that I would feel suffocated without any mouth holes but not the case! Highly recommended,
