Best in the buisness

I absolutely love me Core merino 330 bottoms. I am a full time fishing guide that fishes winter Steelhead on the Olympic Peninsula where it can be cold and wet. With my merino 330 bottoms I am never cold. The perfect piece to add to your cold weather clothing arsenal.

Great base layer

This is my fourth merino bottom from Sitka. I won’t hunt during the cold late season without them. Keeps me warm and dry every time I’m hunting big bucks in the cold of winter.

Best under wader baselayer!!!!!

OK - Let's get started. These 330 base layer pants are excellent. I am utilizing them as a base layer under my fly-fishing waders (Gore-Tex). You hike the stream, and they wick away the perspiration, you stand in the water for hours (high 30's, low 40's temp) and they keep you warm. Sitka please market these to fly-fisherman. I am a huge fan and say "These are worth every penny - Thank you for a great product. " FYI - Fit is true to size.

Perfect baselayer

These merino baselayers matched with the 330 merino half zip is the perfect combo for mid to late season archery hunts here in central Illinois. The are very warm, comfortable, absorb perspiration, and don't itch. I'm 6'1 and 170 lbs and wear the medium bottoms. I wear the zip top in large.

Title: Warmth and Comfort from the Ground Up

The Core Merino 330 Bottom is the perfect companion to the 330 Half-Zip and an essential layer for extreme cold. The merino wool blend is soft, warm, and itch-free, with just the right amount of stretch so it moves with you instead of against you. Even after long days in the field, it stays comfortable and doesn’t hold odor, which is a huge benefit on multi-day hunts. The fit is true to size—snug enough to layer easily under bibs or pants without bunching, but not restrictive. It breathes surprisingly well for such a warm piece, keeping me comfortable whether I’m glassing from a standstill or hiking in rough terrain. Paired with the 330 Half-Zip, this bottom completes a base layer system that keeps you warm, dry, and focused in the harshest conditions. Absolutely a must-have piece of gear if you spend serious time outdoors in the cold.
