Regulate 230 Long Sleeve Base Layer

excellent 1/4 zip

Love this 50/50 merino/synthetic layer. Too bad it's discontinued!

Solid product, but kind of ugly

Not a fan of the giant mustang patches on the shoulders. They look bizarre and cause you to look like you’re wearing shoulder pads. A smaller, less aggressive styling would be better.

Exactly what I was looking for

Wanted a thin, but warm base layer for wading the river for winter fishing. Got both the Regulate 230 top and bottom they've been perfect under my waders, down to 27-28 degrees. Really happy with fitment/quality, which didn't surprise me, as I've also been extremely happy with my previous purchases from Mustang Survival.
