If coziness is the name of your game when bracing the outdoors, the Smartwool Merino 250 Base Layer Bottoms should be right up your trail. Renowned for their warmth and comfort, these were the go-to for many women during those icy night under the stars. Built with a 100% Merino wool fabric, they provided the softness and warmth that you'd expect from a high-quality wool product, all while maintaining a light feel that didn't leave users feeling weighed down.

Buyers highlighted just how comfortable these bottoms were, most notably their snug, yet non-constrictive, fit. Unlike some base layers that constrict or bunch up in all the wrong places, users said these ones provided an exceptionally natural feel. The gender-specific design received several nods for fitting female contours perfectly.

In the warmth department, the Smartwool Merino 250 won potential brownie points. Customers frequently praised its capability to keep them warm even in biting conditions. The heavier knit fabric provides an added degree of insulation. So, those frosty early-morning hikes or winter camping trips will be a whole lot more bearable with these.

These bottoms were also praised for their breathability. This is due to the Merino wool’s moisture-wicking properties that allowed sweat to evaporate easily, providing a feeling of dry comfort, even during intense activity.

The Smartwool Merino 250's durability was also a recurring theme in customer reviews. Users mentioned they held up well to regular washing, with minimal pilling or stretching. So, if you're planning on being out and about often, these could be a great investment.

On the flip side, some users did mention issues with sizing, with a few finding them to be too long, or slightly loose around the waistband. However, once the correct size was found, users agreed that they hug the body well, providing unrestricted movement.

Regarding the price, there was somewhat of a split opinion. Some buyers felt the cost was justified by the quality build, comfort, and duration of wear. Others felt that they were a bit on the expensive side. However, if you value warmth, comfort and durability, and aren't afraid to pay a bit extra for it, these could be worth considering.

The Arc'teryx Rho LT Bottoms grab the spotlight for those venturing out during the cold season, emerging as one of the top performers among long underwear for women. This pair of long underwear manages to strike an impressive balance between comfort, warmth, and ventilation, making it a popular choice among outdoor enthusiasts.

Customers rave about the Rho LT Bottoms for their exceptional built-in comfort. The fabric is a soft blend of polyester and elastane, providing ample stretch to accommodate movement. The wide waistband is a boon, as it doesn't roll down or bunch up when you're on the move. According to some reviews, the fit is snug but not constricting, providing a nice, body-hugging feel without limiting mobility.

When it comes to warmth, the Rho LT bottoms pass with flying colors. Wearers praise the product for its ability to provide substantial warmth when worn under additional layers during cold-weather adventures. The grid pattern on the inside acts as a thermal trap, capturing heat from your body to keep you warm.

Another selling point is the bottoms' breathability. Despite their warmth, the Arc'teryx Rho LT Bottoms cater to the sweat-prone with their quick-drying and moisture-wicking capabilities. Multiple users commented on how they didn't find themselves feeling too hot or too cold but just right, confirming the product's excellent thermal regulation.

However, some buyers were less enamored with the cost. The premium pricing of Arc'teryx products translated over to the Rho LT bottoms, leading to some grumbles about value for money. While many users felt the features justified the price, some wished it was more affordable.

Another minor gripe surfaced around size availability. Several petite users found that even the smallest size was slightly too long, causing some bunching around the ankles.

The REI Co-op Midweight Tights position themselves strongly in the 'great value for money' camp. Offering substantial warmth without costing an arm and a leg, these tights have been much appreciated by budget-conscious outdoor enthusiasts.

Fabricated with a polyester-spandex blend, these tights are sufficiently stretchy to accommodate various body types while ensuring freedom of movement - a crucial feature for any active outdoor pursuit.

What customers count as a standout aspect of these tights is their quick-dry capability. If you're ever caught out in the rain, or break a sweat from an arduous hike, you can trust them to dry rapidly and keep you feeling comfortable and fresh.

Receiving high scores in user-friendliness, the elastic waistband sits snugly without pinching the skin. Also, the flatlock seam construction significantly reduces the chances of chafing, especially during prolonged wear. Many users love that they don’t have to constantly readjust the waistband or worry about discomfort.

However, they're not without their drawbacks. Some online reviewers have mentioned that the sizing chart doesn’t run true to standard measurements and that they had to order a size up or down for a precise fit. Therefore, you might need to take a bit more time and effort deciphering your perfect size, and maybe ordering more than one pair to try them on can be a good idea.

Several online reviews also opine that these tights are not ideal for extremely cold weather. While they provide good insulation suitable for moderate cold, when the temperature drops drastically, they might not prove to be sufficient. If you plan to venture into the heart of winter, consider packing another layer for extra warmth.

Despite the minor downsides, the REI Co-op Midweight Tights hold their own as a genuinely good purchase for those who want quality thermal underwear on a budget. From chilly autumn hikes to brisk mornings in the campsite, these reliable tights would be a welcome addition to your outdoor gear collection.
