SmartWool Midweight Turtleneck

rated 5 of 5 stars Luxurious warmth!!!! WOW! I could just leave it at that but I will elaborate. I first bought the SmartWool NTS 250 bottoms, which I love, so when I saw this shirt on sale I couldn't resist. Although both the top and bottoms are NTS 250 the top is much thicker and sooooo soft. I like staying warm outdoors and this shirt has kept me just that! I wear it all winter and bring it along for all my hiking and camping endeavours in the summer as well. I usually sleep in it when I'm at higher elevations… Full review

First Lite Chama Hoody

rated 5 of 5 stars My First Lite merino clothing keeps me comfortable in the cold mountain mornings and when I am hiking during the warmer parts of the day. Great for layering or for sleeping in on those cold nights. Pull the hood up, cinch it down for added warmth. The Chama Hoody is a versatile top. It can be used as a base layer on those cold hikes through the woods, or as a stand-alone sweater on those days where a jacket is too much. The hood, with its cinch string, is useful in a cool environment, but you will… Full review

SmartWool Men's Microweight Crew

rated 4 of 5 stars A well-made, Merino wool baselayer that has gotten me through the insane cold of January 2014. It's a bit short in the torso for this 6'2" guy. The regular price is a bit higher than I think the product is worth. While I agree SmartWool makes good products, I also believe the price is driven by the name. For that reason, I seldom buy SW products unless I find them deeply discounted. Such was the case with the SmartWool Microweight Crew shirt, which I picked up for $36. While I am satisfied with… Full review

SmartWool Women's Midweight Crew

rated 5 of 5 stars Great wicking wool top! I've used this as a base layer this winter for daily walks in the ever changing New England weather, on runs and while cross country skiing. Would recommend this top for anyone looking to stay warm and dry while being active. I love this top! The sleeves are long enough to pull down over my fingers when cold and loose enough to fold back when I've warmed up. The length is perfect, long enough to tuck in or leave out with no gap at the waist.   I've used this as a base layer… Full review

Wild Country Lightweight Base Layer Top

rated 2.5 of 5 stars A mediocre base layer that probably won't last long in the market, as it doesn't fit well. I picked up this item on sale for $6 at Sierra Trading Post. I have not seen it sold elsewhere. I wore it nearly every day during the month of December, both indoors and outdoors. Had I paid the suggested retail price of $20, I would have felt this was a waste of money. The shirt arrived in its own stuff sack. This struck me as a bit odd and unnecessary. I appreciated the shirt's tagless design. Care for the… Full review

Stoic Men's Alpine Merino 150 Crew - Long-Sleeve

rated 5 of 5 stars Great baselayer! Bought a couple of these on steepandcheap.com for about $30! What a great price for a merino wool baselayer. I've been out with them twice now in the Colorado winter and was impressed on how they regulated body temperature. The sleeves have thumb holes which come in handy to keep your hands warm. They are barely noticeable when not in use. I'm happy with this shirt so far and can't wait to wear them in the backcountry for a couple of days! Full review

Icebreaker Men's Bodyfit 150 Long Sleeve Crewe

rated 5 of 5 stars Well worth the money. I always hang dry mine. It will keep you reasonably warm when it's wet or dry and I love to switch into it when I soaked a different undershirt on the hike up. Fits really nice, breathable, and very good construction. Full review

Icebreaker Women's Bodyfit 150 Long Sleeve Crewe

rated 5 of 5 stars Women's version, really lives up to the hype. Definitely worth the money. Merino wool keeps sheep warm in winter and cool in summer. Period.  It will do the same for you. Once you go wool you're never going back to synthetic for base layer comfort. I always smelled like a barn animal after hiking and camping in a synthetic base layer. No problem anymore. Not only does the merino shirt do better it actually inhibits bacterial growth, the difference is overwhelming.  This material is not the scratchy… Full review

Patagonia Men's Merino 2 Lightweight T-Shirt

rated 4 of 5 stars Nice fit, no itch, use as base in cooler temps or alone in warm temps. I put off buying due to cost, but wish I saved up and got one sooner. I use this as a base in cooler temps and alone when it's warmer. It's nice because it dries quick so when you slow down on a hike or cool breeze comes up I remain comfortable. No seam on your shoulder, requires more care when washing. Full review
