Smartwool is a company that creates high-quality merino wool products that can be used as part of a layering system. When you hunt or plan to spend any prolonged time outdoors, it’s important to have multiple layers of clothing to protect against the elements. Different types of apparel are good for different outdoor adventures and weather patterns. Are Smartwool 150 or 250 products better?
#1. Smartwool 150
Smartwool 150 products all weigh 150 grams, which is where the name comes from. These wool garments are meant to be used as the base layer in a layering system, rather than outerwear. They’re comfortable enough to sit directly against your skin. Aside from the weight and the use of merino wool, different products have many different uses and integrated technologies.
There are Smartwool 150 garments of basically every type of apparel that the company manufactures. You can get a base layer performance shirt to wear underneath your other clothing, a long sleeved shirt, gloves, boxer briefs, and base layer pants that go underneath your heavier protective pants.
Merino wool is favored among many people for climbing and hiking because the socks prevent the building up of moisture on the feet. Since the wool repels moisture, you don’t have to worry so much about sweat and odor, and the material helps keep you both warm and cool depending on your needs.
Smartwool 150 products are designed to be worn next to your skin as base layers. As such, they incorporate technology that responds to your body temperature. When your body is hot, the cooling system helps increase breathability and wick away sweat. When your body is cold, the fabric offers a layer of additional protection and insulation against outside temperatures.
This helps ensure your body stays at an ideal temperature whether you’re doing high endurance hiking or sitting in a tree stand.
The construction of Smartwool 150 apparel tends to be more durable than with many other wool products on the market.
The manufacturer uses core spinning technology to wrap fibers of wool around a core of nylon. This allows the clothing to be more durable and long-lasting than wool fibers alone, but it still remains lightweight and comfortable.
Though the Smartwool 150 is made to be used throughout the year, it won’t be a good fit in the most extreme temperatures. If you’re dealing with very cold winters or very hot summers, you’ll want to invest in innerwear that’s specifically designed for these temperature extremes.
#2. Smartwool 250
The Smartwool 250 can be a little more versatile than the 150 because the apparel isn’t specifically made to function as a base layer. If you’re dealing with very cold weather and need more insulation, you can use Smartwool 250 apparel as your base layer instead of 150. If you don’t want to bother with a layering system in moderate weather, a single layer of Smartwool 250 should keep you warm.
There’s also a wider range of Smartwool 250 products available. The apparel includes a base layer bottom, a beanie, a long-sleeved crew top, a hoodie, and another base layer top. The beanie is included because this gear is made to insulate your body heat in colder weather.
When you’re using a more extensive layering system in cold weather, the Smartwool 250 tends to be the second layer used. The fabric isn’t as breathable as with the 150, and it may be too heavy for heavy cardio workouts. For this reason, the clothing is recommended for individuals who are planning to stop and go outdoors rather than engage in sustained activities.
The fabric is extremely soft and uses an interlock knit to seal in warmth. The knit also adds a natural layer of resistance against odors.
One thing to keep in mind is that this fabric is very thick and very absorbent. It will absorb any moisture surrounding it, which means that it can get drenched in sweat when it lays against your skin. It will also become very heavy if exposed to rainfall.
Unlike shoes, which tend to release multiple improvements to their lines, Smartwool 250 doesn’t refer to an improvement upon Smartwool 150. Instead, the number helps define the weight of the product.
Any Smartwool product that weighs 150 grams is considered part of the Smartwool 150 category, and any product that weighs 250 grams is part of the Smartwool 250 category.
Smartwool 150 clothes are lighter weight and tend to have less dense fabric. If you’re looking for clothes that you can maneuver in without becoming fatigued, these are ideal. They’re also good if you’re going to be hunting or hiking in warm or mildly cool weather.
Smartwool 250 clothes are heavier, so they’re good for people who want stronger insulation when they sit in a tree stand. They’re also good if you live in a place that has a cool to cold climate, or if you’re planning to spend several hours per day out in windy conditions.
Both the Smartwool 150 and Smartwool 250 garments make excellent base layers when you’re spending a lot of time in the woods. The lighter 150 apparel is better for those who want lightweight clothing in warmer weather. The 250 apparel is heavier and better insulated, making it more ideal for those who need a tough base layer in high winds or more intense cold.
