Reviews
I bought both the merino
"I bought both the merino midweight crew base bottoms and top before going snowshoeing in -20 and -30 (Celsius) degree weather. I stayed warm and was able to wear it every day for almost 2 weeks without it getting smelly. I highly recommend. However, if you are tall (I am 6ft), the bottoms do not have a long enough inseam. I usually wear a M bottom, but sized up, as the website told me to, and it fit really well."
— Katrine G. (4/5)
Would recommend
"Definitely performed as advertised. Read the reviews about sizing. I’m often a small but order a medium. The waist was perfect while the rest of the fit through the legs was ever so slightly loose. I was not cold sometimes I was a bit too warm but most of the time I was the perfect temperature while wearing these under my HH ski pants & jacket."
— Rebecca C. (5/5)
I stopped wearing denim jeans
"I stopped wearing denim jeans because I was so much warmer and more comfortable in Helly Hansen LIFA Merino Midweight Base Layers. This is a top quality garment. Stylish, youthful and vibrant colors. Thank you and keep making beautiful garments that are easy care yet durable. More colors would be very welcome also."
— Kristine B. (5/5)
Great base layer for colder days
"The only thing I would do differently is get a different color. I bought light blue and my cellulite is definitely visible! The medium fits well and as expected, the waistband isn’t painful or digging in, it stays put and is comfortable all day skiing. I wore this as a base layer under my insulated helly pants and was never cold! The material is soft and warm without causing me to overheat on a big resort day."
— Jana J. (5/5)
Great base layer!
"I love these merino pants! They’re my second pair. I use them for skiing and camping and they keep me really warm."
— Erika G. (5/5)
Awesome product!
"I absolutely love this pants! Got it for my hike in arctic zone and it did a good job. I size down by reading reviews and it fits perfect. Material and fabric feel nice. Recommend"
— Ulyana C. (5/5)
Warm and not itchy
"I bought my merino midweight base layer to wear for a trip to Iceland in May so I haven’t wore them yet. But I tried they on and they were warm and not itchy. My husband liked them so I bought my husband and son a pair too."
— Joellen S. (5/5)
Highly recommended
"This leggings got me through the polar vortex in Montreal for a 20 minutes walk. I think this is enough to say! My only issue is that it is a bit long but I understand that taller people will need it to be this way. Maybe it would be a good idea to have different lengths of the same size. Otherwise, highly recommended. Keeps you warm without sweating and without being bulky."
