The simple baselayer

  • Familiarity:I gave it as a gift but have feedback to share

It is what it is. Nice lightweight baselayer. A little stretchy, soft material that's breathable. Can't complain! I bought this for my brother who's pretty skinny so if you're 'bulkier' or 'thicker' you may want to size up.

Runs a little small but the pros outweigh the one con. Great Material


Solid Base Layer

  • Familiarity:I've used it several times
  • Fit:True to size

Outdoor Research is one of my favorite gear companies. They make solid gear that is functional without excessive add-on's that are fluff.

This base layer is simple, well constructed, and performs well. The merino wool blend functions as expected by being soft against the skin, wicks moisture, and doesn't stank!

I am 6'1 180 lbs with long arms and the Large fits great. It is a bit snug around the forearms and zipping it up all the way is pretty snug around the neck, so keep that in mind.
