Let’s get started and take a closer look at what the Lynx GWS has to offer.


If you’re going to be mountaineering or backpacking, you want whatever you have in your backpack to be of use. The Lynx is a lightweight sleeping bag, packed with 33 oz of 850+ power fill down. In addition to it being stuffed with high-quality down, it’s made with Gore Windstopper that prevents cold air from seeping through the sleeping bag.

To further increase its warmth and insulation, it’s designed with V-Block Side Baffles that make sure the down stays in its place. As you can see, it’s crafty and clever design only helps to benefit the user. If you’re looking for lightweight and size, then you’ll be pleasantly surprised with the Lynx as it can compress itself into the size of a basketball.


When it comes to backpacking and camping, you want to look for a sleeping bag that’s easy to bundle up and shove into your backpack or car. You don’t want to be spending ten minutes trying to roll it up and make it as small as you can. You want that to be an easy task to complete, as you’ll have other things you’ll need to spend more time on, such as assembling the tent.

Western Mountaineering Lynx GWS Sleeping Bag packaging

When it comes to the Lynx, this sleeping bag is great for compressibility. With the 850+ power fill down and microfiber shell, it’ll compress very well, considering how much down is in it. You’ll be able to compress it in a medium sized compression sack, roughly the size of a basketball.

The Gore Windstopper Shell will make it a little heavier, however, it shouldn’t be a challenge to compress it. For a winter sleeping bag, considering the amount of down in it and the material used, this bag is relatively easy to compress and pack up.

Design and durability

The Gore Windstopper shell allows vapor to escape, ensuring that the performance of your bag is not altered. It also makes the sleeping bag more water-resistant which, if it happens to rains, you’ll be happy you have this feature. It comes with an incredible zipper that will not let an ounce of air enter your sleeping bag, plus, it’ll never snag.

It’s designed with a reverse hood which means that the hood is cut with larger pieces of fabric on the inside as and smaller pieces of fabric on the outside. What this does is provide the user with warmth, comfort and a pillow-like feel for your head. So, you won’t be needing to cinch the hood tight.

The only downfall of the Lynx is that it doesn’t come with any internal storage pockets, which many users enjoy having as a feature.

In terms of durability, Western Mountaineering really went all out on using high-quality materials when designing the Lynx. It’s a tough sleeping bag and you’ll be able to use it for weeks on end without it withering away. Many people are apprehensive about zippers on sleeping bags, as they tend to be the first ones to go, however, the zipper on the Lynx is snag-free and high-durable.

In addition, the shell can withstand harsh weather conditions such as rain and snow, without giving out. The point is, once you buy a Lynx, it’ll be with you for a long time.


If you’re looking for a warm sleeping bag, well, look no further. The Lynx is one of the warmest sleeping bags and stays true to its rating. It’s made with 850+ power fill down which is nature’s best insulator, your body heat is going to circulating inside your sleeping bag.

The hood is also stuffed with down, so you’ll be able to keep your head wrapped up in a pillow of warmth. The hood also comes with adjustments so you’ll be able to customize the fit. It’s designed with a snag-free zipper which prevents any cold air from entering your bag but also allows you to adjust it so that if needed, you can allow enough air to enter the bag.

You’ll be able to sleep comfortably in temperatures as low as -10 Fahrenheit. Out of the Western Mountain sleeping bag collection, the Lynx is definitely the warmest. So, if you’ll be mountaineering or backpacking/camping during the winter season this is the ideal sleeping bag for you.

If you’re looking for a sleeping bag for the summer, you’ll overheat in this sleeping bag. So in that case, you’ll need to invest into something lighter, even a synthetic sleeping bag would suffice.


Let’s just get this out of the way: if you’re looking for a summer sleeping bag, this isn’t the one for you. You’ll fry in this bag if you’re going to use it in the middle of July. This bag is ideal for mountaineering or those who are going camping during the late fall, winter and early spring.

So, when it comes to versatility, in this sense, it’s not as versatile. The main function of this sleeping bag is to ensure that the warmth stays in and the cold stays out.

However, when you look at this sleeping bag for what is it, it’s extremely versatile. You can easily compress this sleeping bag and stuff it into your backpack without it weighing you down. With the Gore Windstopper material, you can sleep in this bag during wet nights and you’ll be kept warm and dry.

This lightweight sleeping bag provides you with warmth, comfort and protection from the elements. How much more versatile can you get?


The worst feeling when you’re camping is waking up with a sore neck and back, which is what many people experience. Why is that? Because they don’t have the proper sleeping gear with them.

If you’re prone to a sore back, you’ll want to bring a sleeping mat, hammock or cot with you. Naturally, what you bring for back support will greatly depend on where you’re camping and how you’re getting there. But comfort also depends on the sleeping bag you have as well.

The Lynx is extremely roomy, so you won’t be feeling suffocated and claustrophobic when you’re in it. This typically is the biggest complaint about sleeping bags as people cannot curl up inside of them or fully stretch out. However, with the Lynx, you won’t have a problem.

In addition, you’re sleeping on high loft down, which is included in the hood, so it’ll give you a very cushioned sleep. The snag-free zipper is also another great feature as it won’t let annoyingly cold air in, and gives you the extra ease of zipping it.

Unique features

When looking at the Lynx there are a couple features worth mentioning. The Gore Windstopper material is not included with many sleeping bags, however, really give the sleeping bag an extra level of added protection. If you’re going to be in wet environments, then having a sleeping bag with this feature will add longevity to your sleeping bag.

The zipper on the Lynx is very durable, anti-snag and will keep the air from entering through the zipper’s teeth. Though this is an overlooked and small feature, it’s extremely important.
