Why We Built The Backcountry Spruces Merino Baselayer Bottom

Our Backcountry Spruces Merino Baselayer Bottom is an ideal base for active pursuits on snowy winter days. Durable nylon is woven into merino wool, delivering soft next-to-skin comfort that's warm and durable. While thermal comfort might be the name of the game, the fabric is also moisture-wicking and odor-resistant, so we can play harder and stay out longer.

Warm base layer

I've used it several times

These are soft and comfortable but I wish they were a longer/ taller. On me they are not as high rise as they are in the model pics and are slightly cropped- not the end of the world since I knew they would be slightly cropped from the pics. I like the band at the top, I think it holds a little better than some of the other merino base layer pants I've had.

Practically perfect

I've used it several times
Size Bought:
5' 6"

I absolutely adored last year's version of the Spruce Marino bottoms - this year's version has a few changes. These are still incredibly soft and are not see through. They do not stretch out too much while wearing even multiple days. I do not put them in the dryer so I can’t speak to shrinking. I don’t personally see the waistband as an improvement- it is scratcher than last year’s model. Also not a huge fan of the shorter length despite them being advertised as full length (above ankle at best even at my height). Overall- these are very good but I wish they hadn’t messed with last year’s perfection.
