Reviews

Comfortable year round

"The 200 weight Oasis shirt is thick enough that the mosquitoes can’t bite through the fabric. The fabric keeps me warm enough and I don’t sweat. When the colder weather arrives in late October, I will wear this shirt under a Pendleton [wool] sweater to stay toasty warm. This 200 weight is perfect for year round comfort."

— Eric-Snowy W. (5/5)

Perfect sleep shirt at altitude

"This shirt is warm and breathes well and is the perfect shirt to wear to sleep. It doesn't stink like synthetics that don't breath or cotton that soaks up sweat and takes too long to dry. I live at 7,400 feet and this shirt is the perfect weight 10 months out of the year."

— AE F. (5/5)

Absolutely love it! The best

"Absolutely love it! The best base layer by far. Used the previous iteration bought about 8-9 years ago for hiking, skiing, flyfishing in cold climates - northern Canada in October. Zero sweat accumulation or odor after 5 -7 consecutive days of wearing in the backcountry. Decided only one is not enough and I liked this color so I bought two more (and the respective long johns)"

200 weight wool keeps you cool and mosquitoes free.

"The reason I like the 200 weight merino wool is because the mosquitoes can’t bite through the fabric. I walk my dog 4 or 5 nights a week at Lake Marie (elevation 10,500 feet) in the Snowy Range in Wyoming. The temperature is usually about 60 degrees F. There are thousands of mosquitoes around the lake trail, but I don’t get bit because of the thickness of the wool fabric."

A definite base layer only but a good one at that

"Great product. Comfortable and will perform well as a merino base layer (sweat mitigation anti stink etc). However it’s definitely only a base layer. The neck is cut very wide and doesn’t sit like a causal t shirt. The length of the torso is short as well. Slim fit is fine as again this isn’t a casual/baselayer combo…just a baselayer. Their 150 tech tee is perfect for everyday wool wear so I am going to invest more in those than this product as wool base layers have a very specific use case."

All round solid layer

"I wear this layer other than hot days of summer. I pair it with a wool hoodie on cool days. I work in it I hunt a lot in it. Ski in it all winter. Breathes really well while still holding heat. Doesn’t hold odor. First time buying this product and will buy again."

Merino wool at its finest.

"As expected this merino wool is super comfortable. The fit is just right and insulation value is perfect (not too warm or too cool)."

Sizing is for shorter people

"I'm a medium in most clothing. 5ft 11in and about 160-165lbs. This shirt is far too short in sleeves for anything active and the body was a bit short as well. The chest and stomach sizing was spot on so I wouldn't want to size up. Build quality looked good and the material thickness was just what I wanted. Overall I'm disappointed. For someone 5'8/9 ish this would be great"
