Your do-it-all merino top.
Built for travel, trail, and everything in between, our Lost Boys Merino collection delivers lightweight comfort and performance in one versatile layer. The merino naturally resists odor, regulates body temps, and wicks moisture, keeping you fresh no matter how far you roam.
Soft, stretchy, and breathable, it moves with you from high output adventures or long travel days. Flatlock seams prevent chafing under packs, and the low bulk design makes it perfect on its own or as a base layer.
Part of the Venture Far Series, it’s crafted with premium materials and refined construction built to handle years of hard use and big miles. Packable, durable, and effortlessly functional, it’s the shirt you grab when you want one layer that can do it all.

Fantastic Merino Shirt
I traveled with this for a few weeks in a hot, humid environment and just rinsed it out in water a few times to keep it fresh but it never got smelly like a good merino! Fabric is nice and soft.

Good For Cycling In Cold
Bought it for an extra layer for this winter cycling season. It's light breathes really well and help retain some warmth without overheating. Doesn't retain odor like pure synthetics.
Taylor
Amazing. My standard for KETL stuff, and it delivers.
As with everything I've ordered from KETL, the quality, comfort, fit, and look are awesome.es, expensive, but I'm a minimalist, and each piece of clothing I buy needs to be a 9/10 in all areas. KETL consistently delivers, so the value is there.

Very nice feeling shirt. Soft, breathable. Does let wind through a bit so don’t count on it alone if you’re dealing with brisk winds. Great for exploring with the dog
Awesome top! Looking forward to using it out on the trail. It is extremely well made and of the highest quality materials.
Fantastic quality and build. Would have rated 5 stars but the neck line is a little on the larger side, which may be specific to my item or taste. Either way, not a big issue, and otherwise fits very well.
Probably the best merino based long sleeve running shirt on the market. I typically run hot, and find that this is good on long run days, dries well when sweaty or wet. Hesitated with 5 stars as the only thing holding me back is that the neck hole is a bit wide and feels pretty open, and not as much coverage as a normal tee, or when wearing a trail vest.
I like the way it feels and makes me look!
Great shirt! It is daily go too. I will definitely buy another when it is back in stock. I hope for some other colors as well in the future.
Super soft. Fits well. Will enjoy this gear in Colorado.
It feels very comfortable. I do wish I got it ine size smaller but it still fits nice. Super comfortable, I can’t stress that enough!!
Amazing quality and breath ability
I love yhis style especially the long sleeve version perfect fit
This shirt is the perfect fit and comfortable. I wore it multiple times so far in 95+ degree temp and high humidity and the shirt has held up like a champ. Would highly recommend
Fits and feels good.
I have enjoyed my purchase of LB Merino LS top since receiving so much a ordered a second.
Looking for reasonably priced wool that can reduce luggage for long trips. Was concerned that this was not 100% wool. To test this, I have worn this shirt five days only hanging it up to air out and it still does not retain odor. The fabric blend makes it very versatile. You need to make this in more colors.
This is really good quality Marino wool. I use it on almost all my gravel rides!
This marina wool is top notch, finest quality stuff. These guys really know what they’re doing.
Fits great
Amazing fabric feels great on the ski, just loose enough fitting, warmer than the departed travel tee shirt which is still my favourite
A bit short for my 6’4” frame but otherwise great feel.
Great top. I wear it under my scrubs for a long work shift, and don’t smell at the end of the day, plus temp regulates. Appreciate the thumb loops, which makes it easy to layer and also sun protect the hands.
Great base layer and summer top high quality
High quality and soft to the touch. Everything you would want from a light wool shirt. Fits “loose” in my opinion. Highly recommended!
