Customer Reviews Arc'teryx Kyanite Baselayer Bottom

These pants are the best thing that has ever happened to me. I always run cold and I used to be the person that weared a base layer and a pear if sweatpants. But with these I can just throw these on under a shell pant and I'm warm and toasty all day! I reach for them every day!

Very warm and comfortable, it is my second purchase of the same outfit. Excellent for layer of cold winter hiking. I like it for its soft and warm feeling.

She really likes they. Very cozy and nice amount of stretch. They do run a touch big. She sized down a size.

I purchased myself a set as I was shopping for my husband. What a surprise, the fit and the comfort. SO worth every penny.

The fit and comfort are perfect. The form fitting stretchability is warm and comfy. Have not used them in -20, but will have to wait for that inevitability. Keep up the good work, I love the design.

The Polartec Power Stretch Pro base layer is warm, flexible, and impressively versatile for cold conditions. It delivers excellent insulation while staying breathable during high-output activities and long days at work. I love wearing it at work because I'm always cold, and it keeps me consistently warm. It doesn't itch and has none of the chemical smell I sometimes notice with Patagonia's fleece. The four-way stretch and soft brushed interior make it extremely comfortable. Overall, it's a reliable, durable choice for anyone needing a high-performance winter base layer. I got 5 of them! < 3

Loves these !! High quality and fit! Color excellent.

Comfortable, soft, my go to for layering under ski pants. Not super snug on the leg fit.

I had two pairs of the previous version. My puppy put holes in them. The new version has an updated waist that will be even better for backpacking. I like the thigh pocket as well - fits a phone so I am more likely to take photos of my adventures.

This is definitely a new winter staple for me! I wore this underneath another pair of pants when hiking in the snow and it kept me warm when it was about -2 C outside. I don't think I would wear this on its own unless I'm lounging at home

Warm without being bulky, stays dry and fits really well.

I bought a pair of these baselayer bottoms in the Stratus colour in my usual size (medium) and am obsessed! They are sooo comfortable and soft, and have a nice stretchy waistband that is quite high so they'll stay up. I've worn them under my uninsulated ski pants and they keep me warm on resort days up WhistlerBlackcomb. I'm super happy with these and are my favourite piece of ski gear I've purchased this season. If you want a more compressed fit, size down... I could probably get away with a size small and I don't say that often.

These bottoms are super soft and comfortable, and are my go-to base layer for cold weather low output activities like easy hikes, mellow resort days, or just wearing around the city. I like the side pocket for my phone if i'm wearing them as my only layer, or my keys if they are under a shell.

Love the leg side pocket for keeping the phone warm while touring.

These pants are soooooo warm and comfy!! I love the side pocket.

I purchased myself a set as I was shopping for my husband. What a surprise, the fit and the comfort. SO worth every penny.

Polartec Powerstretch is a great product for sure the only downside was at the ankle - baggie. If petite sizes were offered that baggie loose ankle would probably not occur.

The comfiest thermal leggings! I would keep them on all winter if I could. They are my go to for winter hiking / snowshoeing in cold conditions. Super stretchy and perfect fit. The side pocket is a nice feature & keeps my phone warm!

These are what I most looked forward putting on in my tent after a long back of hiking in all weather conditions! Breathable, warm + not too tight. My only con is that after wearing them every night on the CDT (some daytime hiking too) is that they do become see through.

The fit and styling is much improved from my last pair of RHO leggings and was excited to find that I could replace them with these. However the fabric seems thinner and not as warm as some other polartec tights I have which are soft and cosy for my dog walks in frigid weather. I feel that these are really a base layer or to be worn in milder weather. I like the tatsu color but would prefer a darker olive and since I am on taller side, another 1/2" in length would help to tuck inside socks/boots. Since I have already worn them, I plan on keeping them but am still on the hunt for some soft warm leggings!

Le vtement est vraiment trop court et le tissu ne correspond pas la qualit habituelle des produits Arc'teryx. Je l'ai donc retourn.

I don't know if it just got a defective product, but I bought these leggings and the matching top and within less than six months of very light use, the fabric has holes everywhere (both the top and these bottoms). Not holes at the seams.... no, just random holes in the fabric, and not even in high wear spots. I've never had a baselayer do this before. It was comfortable while it lasted, but overall extremely poor quality.
