How to measure
Chest: Measure around the fullest part of your chest, keeping the tape level and snug under your arms

Sleeve: With your arm relaxed at your side, measure from the center back of your neck over the shoulder and down to your wrist.
HATS- Measure around your head, right above your eyebrows

"warm, well made, good for wearing around before & after fishing."
— Paul W. (5/5)
"The Men's Strata 330 Mid-layer bottom is well-made, fits snuggly and is a major upgrade over the thin, polyester pants I was using under my waders. My previous bottoms are fine for downhill skiing -- mainly because I'm constantly moving. But when you're fly fishing in chilly water, there's not as much movement, so you can get cold pretty fast. There's no reason to freeze your butt off. Just get a pair of Strata 330 Mid-layer bottoms and you'll be set. These pants allow me to fish my local rivers in Northern California in January and February."
