Sleeping bags are a tricky piece of gear to buy. Ideally you’d be able to buy just one and use it for every season, but unfortunately it doesn’t work like that.

Gear experts will generally recommend you buy a bag rated for the coldest weather you think you’ll encounter, which means if you camp in the colder seasons of the year, you need a bag rated for zero or sub-zero temperatures. If you get one with such a low temperature rating, however, it’s often far too toasty for fair-weather camping. On the flipside, if you get a sack rated for warm weather, it won’t be good for anything other than spring/summer trips. Up until now, the only solution to this problem was to buy two or more sleeping bags – one for cold weather and one for fair weather, and maybe even one in the middle if you can afford it. But now there’s a better solution.

Kammok, the gear manufacturer who popped onto the scene last year with the Roo backcountry hammock, has developed a modular sleeping bag system that allows the user to add or remove insulation depending on the level of warmth needed.

It starts with a shell designed with Kammok’s patent-pending “variable warmth technology,” which is basically a system pockets of designed to accommodate interchangeable baffles. Baffles are little pockets of insulation, and while they’re commonly used in traditional sleeping bags, the ability to remove and change them is an entirely new concept.

By stuffing Thylacine with different types of insulation (baffles can be filled with down, synthetic down, or a hybrid mix) and different fill levels, you can optimize the bag’s warmth and weight to best suit your needs. It also features a special locking system to keep the baffles properly positioned and prevent cold spots, and to help you manage extra fabric when the bag isn’t completely full, it’s even got a cinching system to ensure it’s always snug.

Kammok is currently raising money for it’s first large-scale production run on Kickstarter. Backer prices range from $200 for the most basic model, up to $650 for the most decked-out version with tons of extra baffles. Find out more on Kammok’s website.

The Apollo wearable is proven to help you sleep better (and it’s on sale)

Stress, anxiety, and insomnia are all concerning things that just about everyone struggles with at one time or another. Maybe you can sleep, fending off insomnia, but you lack quality sleep and don’t feel rested in the morning. Or, maybe when it’s time to kick back and relax, you just can’t find a way to do so. There are many solutions for these issues, some work, and others don’t, but one unlikely area of support can be found in a modern, smart wearable.

Medicine is the obvious choice, but not everyone prefers to go that route. There is an answer in modern technology or rather a modern wearable device. One such device is the Apollo wearable, which improves sleep and stress relief via touch therapy. According to Apollo Neuro, the company behind the device, which is worn on your ankle, wrist or clipped to your clothing, it sends out waves of vibrations to help your body relax and reduce feelings of stress. It's an interesting new approach to a common problem that has typically been resolved via medicine, therapy, or other more invasive and time-consuming techniques. The way it utilizes those vibrations, uniquely placed and administered, to create a sense of peace, makes us ask, can it really cure what ails us? We’ll dig a little deeper into how it achieves what it does and what methods it’s using to make you feel better.

What comes after Webb? NASA’s next-generation planet-hunting telescope

An illustration shows how NASA's Habitable Worlds Observatory would measure the atmosphere of distant planets.

When it comes to building enormous, complex space telescopes, agencies like NASA have to plan far in advance. Even though the James Webb Space Telescope only launched recently, astronomers are already busy thinking about what will come after Webb — and they've got ambitious plans.

The big plan for the next decades of astronomy research is to find habitable planets, and maybe even to search for signs of life beyond Earth. That's the lofty goal of the Habitable Worlds Observatory, a space telescope currently in the planning phase that is aimed at discovering 25 Earth-like planets around sun-like stars.
