Core Merino Bottom - Excellent quality as usual for Sitka
Material is comfortable; however, not as thick as expected. Warm but not hot.

Amazing Core Layer!
Just going into summer in Alaska and went camping at Denali. The nights get cold and much colder there as well as that particular night. These kept me toasty warm, although a bit overkill with my 0 degree sleeping back. Thank you Sitka!

Best base layer
I purchased the Core Merino 330 bottom to replace another company's product that failed spectacularly. The 330 is a true to fit durable base layer that has proven it can withstand all the torture I have put it through. I use the 330 for hunting and work and I have not been disappointed with the product quality, durability, and function. I recommend the 330 bottoms to anyone who needs a high quality base layer that will perform to the highest standards.

Very warm.
6’1” 200 lbs. normally a 34-35inch waist but I’ve been blessed with a thicker butt and thighs. Bought an XL. A large may have been better if I wanted them to be more tight to the skin but I have no problems with them slightly loose.

Overall I like the Core
Overall I like the Core Merino 330 Hoodie, but I feel like it just isn't "that warm. " I got it, intending to use it as a base layer, and I still found myself having to add extra layers. I would just like to see more warmth value at a premium price tag. Also, if this was offered in a Tall size that would be even better. I am 6'3" about 245lbs, and I got the XL, but its short on me. Would love to see a Tall size available.

Core Merino 330 Bottom
I have yet to wear the 330 core bottoms but they feel of great quality and craftsmanship. I think that the idea that you can remove them with their side zippers without totally undressing/ removing your boots is simply brilliant ! I just hope that the zippers hold up! A great piece of kit; especially for those that will be on the move as the day warms up.

Honest Review
Purchased these for my first Mulie & Elk hunts in Colorado. These were fantastic. For the Mulie hunt, we had temps around 32° F in the morning and about 55°F in the afternoon. These kept me warm in the morning and comfortable in the afternoon. Also kept the smell to a minimum. 10/10.
