Filtering water in the backcountry can be a serious chore, and if you’ve never had the pleasure of painstakingly squeezing water from one container to another one liter at a time, I cordially invite you to try it at home and let me know what you think. That very reason is why I was excited to see that the new Lifestraw Peak Series line of water filtration devices includes a pair of collapsible water bottles, each with its own compact internal filter. One device to rule them all…

I’ve put these bottles to good use on my last several camping, hiking, and trail running excursions, and was impressed enough by their outright versatility to share my findings with our esteemed readership. Long story short, I think these bottles make a great addition to just about any traveler and/or outdoorsman’s gear collection, and here’s why.

What Is the Lifestraw Peak Series Collapsible Water Bottle?

The Lifestraw Peak Series collapsible water bottle is a flexible water bottle with a built-in water filtration system that removes harmful bacteria, parasites, and microplastics from drinking water. They come in both 650ml and 1L sizes, and feature compact and modular filters designed to work with other products in the Peak Series line as well as standard disposable water bottles.

The bottles are a versatile solution for anyone who needs to filter sketchy or potentially untreated water. That includes hikers, backpackers, and trail runners who need to gather water from rivers and streams in the backcountry as well as travelers in countries whose water may contain harmful bacteria and protozoa (if you’ve ever experienced Montezuma’s Revenge firsthand, you know what I’m getting at here). The collapsible nature of the bottles themselves makes them more portable and packable than standard reusable bottles from folks like Nalgene or Miir, yet their durable construction is much more tear and puncture-resistant than your average collapsible bottle.

How Do They Work?

These Lifestraw bottles filter all manners of nastiness out of drinking water using a membrane microfilter, which removes particles down to as small as 0.2 microns with over 99.99% efficiency. Because these bottles use a flexible membrane rather than hard plastic or aluminum, they can also be folded down and stowed away between refills or when not in use.

Both sizes feature Lifestraw’s new compact filter, which measures just over 3 x 1 inches. The filter is small enough to leave inside the bottle for simple drinking on the go, but can also be attached to the bottle externally and used as a “squeeze” system for any number of outdoors applications like filling up a cooking pot or refilling secondary reservoirs for longer stretches.

What I Like About The Lifestraw Peak Series Bottles

The New Filter System Is Super Versatile

For me, the value of the new Lifestraw bottles is all about their versatility. For typical day-to-day use, whether it’s running, hiking, traveling, or just staying hydrated, you just fill the bottle as you normally would, then replace the cap and drink straight from the spout. For backpacking purposes, the filter can also be removed from the inside of the bottle, then reattached to the outside, allowing you to filter water into a second reservoir of choice, similar to a Sawyer system. That same filter is also designed to attach directly to any standard wattle bottle (Smart Water folks, I see you), and used as a standalone filtering solution. For me, that means you’re getting a litany of uses out of a single product, which adds serious value.

The Collapsible Bottle Is Insanely Tough

Collapsible water bottles are nothing new, and distance runners have been using them for years with generally good results. Unfortunately collapsible bottles also have a reputation for being somewhat fragile, which doesn’t bode well for backcountry shenanigans. Lifestraw’s new bottles are hilariously tough, and I know that because I tested them by repeatedly throwing them as far as I could down the trail (objective scientific data is a hallmark of good reporting). I was surprised to learn how well these bottles fly, but even more surprised to find that they were in perfect working order every time.

Every Purchase Does Good in the World

One of my favorite things about Lifestraw as a company is its focus on humanitarian work. Lifestraw has been working for years to provide children in need safe drinking water, and for every 500 products they sell, they provide a large-scale purification system to a school, which translates to five years of safe water for 100 kids. Put simply, every product they sell equates to one full year of safe drinking water for one child, and that’s money well spent.

What I Don’t Like About The Lifestraw Peak Series Bottles

The Filters Aren’t the Longest Lasting

Lifestraw’s new Peak Series filters are rated to filter 500 gallons of water before it’s time to replace them. Granted, that means you could use a single Lifestraw filter for every gallon of water you drank for the better part of three years, but there are similarly sized and priced filters out there rated for as much as 100,000 gallons (the equivalent to a lifetime of use). It’s a minor complaint, but one worth pointing out nonetheless.

The Bottles Aren’t Always Pocket-Friendly

If you’ve used collapsible bottles before, you probably know they can be a little awkward to get in and out of pockets due to their lack of structure. Lifestraw’s collapsible bottles can be particularly awkward in that regard because they’re on the wider side (just over 3 inches when filled) and also feature a textured outer surface that’s great for gripping in your hand, but really fights back when you try to stash it in a tight mesh pocket. The bottles were a great addition to my backpacking bag, which has large enough side pockets to easily slide in and out of, but on my smaller day pack and running vests, they were a chore to get in and out.

FAQs About The Lifestraw Peak Series

Do Lifestraw Filters Filter Out Viruses?

Lifestraw Peak Series filters are tested to remove 99.999999% of bacteria, 99.999% of parasites, and 99.999% of microplastics, but they are not rated to filter viruses. That’s industry standard for water filters, and if you want to step up to virus-level filtration, you’ll need to look for a water purifier rather than a water filter.

Are Lifestraw Filters Compatible With Other Systems?

The short answer here is yes, because most all outdoor water filters are designed to work with standard water bottles. That means they all share the same thread design, so you can attach the filter in your Lifestraw collapsible bottle directly to a Sawyer Squeeze bag, Cnoc Vecto, or pretty much any other industry-standard filtration system using the same threaded attachment.

Should You Buy a Lifestraw Peak Series Collapsible Bottle?

I think the Lifestraw Peak Series collapsible bottle is a well-made and impressively versatile piece of gear. In the smaller 650ml size, the bottle works as a great option for trail runners who want to be able to refill out on the trail, travelers who want to avoid foreign bacteria and parasites, or for regular everyday use for anyone who’s concerned about the microplastics in their drinking water. In the larger 1L size, these bottles offer a viable alternative to backpackers who want to ditch disposable plastic options and add versatility to their loadout. Regardless of what you use these bottles for, the fact that they’re affordable and help support a great cause is icing on the cake.

Great Smoky Mountains National Park

Ever since the devastation of Hurricane Helene, Great Smoky Mountains National Park has slowly but surely been reopening sections of the park following reconstruction efforts. The Cosby Area, which is a popular place for visitors to hike, camp, and picnic, is next on the list. As of May 12, 2025, the Cosby Area has officially reopened following the completion of a culvert replacement under Cosby Entrance Road.

This is one of many rehabilitation projects in the area aimed at protecting aquatic species and managing water flow, since flood damage has been a major concern. Heavy rainfall, flooding, and recent debris buildup have heightened risks in the area.

Crystal Cave at Sequoia National Park

Crystal Cave, which is Sequoia National Park's most popular attraction since the park's opening in 1940, will finally reopen for guided tours on May 23 after four long years of closure. These closures were due to several consecutive natural disasters, including the 2021 KNP Complex wildfire, as well as 2022 and 2023 winter storms which brought heavy snow, flooding, and landslides.
“The opening of Crystal Cave is a big step forward in disaster recovery for Sequoia and Kings Canyon,” said Clay Jordan, Sequoia and Kings Canyon National Parks superintendent. “We’re excited to be able to reopen this incredible attraction to visitors and encourage people to enjoy all of the beauty and wonder these parks have to offer.”

Restoration efforts have been extensive near the Giant Forest, where Crystal Cave resides. The Sequoia Parks Conservancy replaced several power lines, stabilized roads, and removed almost 3,000 hazardous trees, with 2,000 more to go.

Do golf balls go bad? Here’s how to know when it’s time to toss them
Sketchy golf ball? Here's how to see if it's still playable
Golf ball near the hole

Maybe you've found a box of old golf balls in your garage, or an unclaimed one out on the fairway. You might be wondering, do golf balls go bad? Modern golf balls are actually pretty robust, lasting as long as five or ten years or more without significant degradation, but it's always good to check. Golf balls can degrade over time, and the signs aren't always obvious. Here's everything you need to consider when teeing up with old golf balls.
How to tell if your golf balls are bad

Look for structural damage
The first thing to look for is structural damage. If your golf balls have visible scuffs, cuts, or cracks from play, they aren't going to serve you well out on the fairway. These deformities, even if they are small, can affect the aerodynamics during flight. You might be okay with very minor dings, but use your best judgment.
Checking the health of the core
If your golf ball has no structural damage, now it's time to check the health of the core. I like to give them a gentle squeeze to see if they are firm and consistent all the way around. A bad one will feel softer or even squishy in places. Then, gently bounce the golf ball on a hard surface and compare it to a new one. If it bounces almost as high, that means that it's likely still good.
The saltwater test
Epsom salt isn't just great for getting rid of sore muscles. A while ago, Bryson DeChambeau made some waves for his creative method for testing the balance of his golf balls. Golfers have been doing this for a while, but he went on to win the U.S. Open with this golfing hack.
