The Feathered Friends Snowbunting EX 0 is a serious sleeping bag for serious outdoor adventurers. This top-tier, cold-weather bag is the go-to choice of many winters campers and backpackers, and for good reason.

Firstly, it's no lightweight. Tipping the scales at 3 pounds 2 ounces, this bag was made with warmth in mind. The Snowbunting EX 0 doesn't cut corners when it comes to insulation. The bag uses high-quality, 900+ fill power goose down, providing stellar warmth-to-weight ratio. Snug and cozy, many owners reported staying comfortable in temperatures plunging to 0 degrees Fahrenheit.

The bag is also applauded for its DWR treated Pertex Shield EX outer shell. This breathable, water-resistant barrier effectively keeps moisture out while permitting unwanted body heat and condensation to escape. Users have found this feature particularly handy during snowy or damp nights.

Where this sleeping bag really shines, though, is in its design. It includes a contoured hood and a roomy footbox, which allowed users to wear extra layers or boots whilst sleeping. Also, owners felt the full-length zipper gives them the freedom to vent and control their body temperatures effectively.

However, the bag is not without its detractors. Some users have complained that, despite its warmth, its packed size is quite large compared to competitor models. Despite the high-quality insulation, it doesn’t compress down as much as one might hope for a bag at this price point. This may not be an issue for some, but for those to whom every inch of pack space is crucial, it's worth noting.

Another downside mentioned by a few reviewers is the price. The Feathered Friends Snowbunting EX 0 is one of the pricier winter sleeping bags on the market. That said, most owners feel that the quality, warmth, and durability of this bag more than justify its higher price tag.

In short, the Feathered Friends Snowbunting EX 0 offers excellent warmth, an effective water-resistant shell, and ample space. It represents an investment piece for the dedicated winter adventurer. Despite its larger packed size and higher price, most owners agree it's a purchase worth making if you're serious about staying cozy and dry in frigid conditions.

Reasons to Buy

• Excellent warmth-to-weight ratio
• Durable and high-quality manufacturing
• Plenty of room to move around
• Superb insulation and temperature management

Reasons to Avoid

• A bit pricey
• Might not be spacious enough for larger individuals

With its premium material and design, the Western Mountaineering AlpineLite truly shines as a lurker in the cold. It's a beaut of a sleeping bag that boasts a 20°F rating, making it a must-have for those chilling winter escapes.

The AlpineLite didn't just stumble upon its rating. It's packed with 850+ fill power down, which does wonders for insulation. The loft is substantial, providing outstanding warmth to weight ratio. Lots of users chimed in how it was incredibly light for being such a warm bag, just showing how well designed it is.

Another popular opinion among users is how roomy the sleeping bag is. The AlpineLite offers extra space without overdoing it; it's comfortable without being unnecessarily large. This provides an excellent balance for those who dislike confining mummy bags but also want to keep their pack weight down. Users could wiggle around comfortably and sleep in various positions, really upping the comfort factor.

What's more, it comes with a full down collar that helps seal in the heat around your neck area. A number of users pointed out how much they loved this feature, especially in those biting cold nights in the middle of nowhere.

Let's talk durability. The outer shell is made of a lightweight yet sturdy material that holds up pretty well. Some users mentioned that they've had the bag for a number of years and it still holds up like new, which is absolutely stellar!

However, it's not all sunshines and rainbows. A few users noted that the zipper can occasionally prove tricky. They mentioned experiences of the zipper snagging on the bag's material, which could be inconvenient in the middle of the night.

Furthermore, the AlpineLite is on the higher end of the price spectrum. We understand that this might make some shoppers pause. That being said, most users said that they got their money's worth given the bag's performance, warmth, comfort, and durability.

Also, keep in mind that, while offering enough space for comfort, the AlpineLite still follows the mummy design. If you're the kind of camper who feels overly confined by such a style, this might not be your cup of tea.

The Mountain Hardwear Lamina Z Flame has been a popular choice amongst backpackers and campers braving the chilly winter nights. The Lamina Z Flame, as the name suggests, is hot on performance when it comes to heat retention. You'd be hard-pressed to find yourself shivering in the night with this one.

This sleeping bag uses proprietary synthetic insulation. It's designed to provide optimum warmth, and that is exactly what most customer reviews online say it does. Besides the loved warmth, users have also praised this bag for its lightweight nature despite the incredible insulation. Its light build is a major hit, especially for those who carry their gear on long treks.

As a complementary feature to the warmth it provides, the Lamina Z Flame also incorporates what the brand calls a 'welded Lamina construction'. This technique, according to users, significantly reduces cold spots, maximizing the warmth this bag provides throughout.

While it's well-loved for its heat retention abilities, some reviewers cited that the Lamina Z Flame might be too warm for any weather above freezing point. It's not the most breathable out there, and some backpackers recommended getting something else if you're camping in warmer areas.

Durability seems to be on point with the Lamina Z Flame too. Many of the reviewers pointed out that this bag feels sturdy and has held up pretty well on their numerous outdoor adventures.

Nevertheless, it's important to note some users mentioned the size discrepancy issues. Several users reported that the bag seems smaller than advertised, so size up if you’re on the taller side.

Overall, buyers rave about the warmth, lightweight build, and sturdiness of the Mountain Hardwear Lamina Z Flame, making it a generally well-loved bag for winter camping. However, like any product, it's not without its minor flaws, and the potentially tight fit is something to keep in mind when considering to buy.

When a blizzard hits mid-climb, you don't want to be stuck halfway up Everest with a sleeping bag that can't stand up to the cold. Thankfully, this bag doesn't have that problem.

One user claimed that it's 'like sleeping in a personal igloo', thanks to its top-quality 900+ fill power goose down insulation.
