MSR Category Director Chris Barchet answers a few questions about the design and performance of the MSR HyperFlow microfilter.
Who was the HyperFlow microfilter engineered for and why?
Today’s outdoor adventurers are going faster and farther. They need solutions that increase their speed and efficiency in the mountains. So the design goals of the HyperFlow were very simple: It needed to be light and it needed to be fast. Most pump filters weigh about a pound and produce around 1 liter of water per minute. The HyperFlow comes in under 8 ounces and delivers 3 liters of clean water per minute. It’s the lightest and fastest pump available. We engineered it for anyone who needs a reliable supply of clean water on adventures where weight or speed is a priority.
What makes the HyperFlow design unique in the wide landscape of filters?
Beyond its ultralight design, it uses hollow fiber technology to deliver water 3 times faster than most other filters. Also, the Quick-Connect cap makes a fast connection to any widemouth bottle, making it very versatile.
What exactly is hollow fiber technology?
Hollow fiber was developed in the medical industry to separate particles in blood and other fluids. It’s effective for water filtration because the fibers’ pore sizes can be controlled to allow water to pass through but not harmful microbes.
The filter consists of a bundle of these fibers. Each fiber looks more like a straw, with a hollow center. The walls of the fibers have those microscopic pores. Water enters the fiber and the force of the pump pushes it through the pores. The harmful microbes and particulates are trapped inside the fibers until the filter is backflushed. Read More →
All MSR® tents are designed with long-term durability in mind, but anything can happen in the backcountry. Even a small rip in your rainfly can expose your tent to the elements, and a little tear can quickly migrate and become a bigger problem. Repairing it in the field can be your best bet, preferably before it starts to rain. Here are three solutions recommended by MSR engineers and designers who have field-tested tents to their limits.
Solution #1: Use the MSR® Fabric Repair Kit
Our first choice for quick, easy and permanent tent repairs in the field are self-adhesive fabric repair patches like the ones included in the MSR Fabric Repair Kit. Simply clean and dry the torn or damaged fabric area, place a patch on both sides of the tear, and you’re done. Read More →
In this video we explore the superior traction technology that sets MSR snowshoes apart from the competition. Engineering 360-degree traction around the snowshoe’s edges, while maintaining lightweight performance, offers better grip and stability on traverses and steep climbs. Learn more about MSR snowshoe technology and the distinctions between our snowshoe models here.

Prior to arriving in Gates of the Arctic National Park in Alaska, my packrafting expertise solely relied on a 45-minute escapade at a neighboring lake back home in Colorado. Sure, floating around the pond gave me a sense of confidence in the buoyancy of the rafts, but that was about all I walked away with in terms of packrafting knowledge. Since packrafting is an up-and-coming sport, I’d like to save other beginners from the trouble we encountered while becoming familiarized with the boats on the Alatna River. Not everyone should suffer as we did!
What is packrafting?
In short, a packraft is an inflatable individual raft that can pack down to such a small size that it can fit inside a pack while backpacking. Once hikers reach a river, they can remove the raft from their pack, blow it up with the included inflation system, and let the adventure continue on the water. The boats do add some weight to backpacks since the raft, spray deck, paddles, and PFDs weigh roughly 8.5 pounds, but it is worth it. Hiking and rafting allow adventurers to see more terrain and cover more mileage while still traveling under their own power. Read More →
Introducing the reinvented MSR Hubba Hubba NX tent.
For over 10 years the MSR Hubba Hubba tent has been a bestselling backpacking tent, so when we decided to create a new version, we first asked a question that guides all of our design work: “what’s the problem we’re trying to solve?” Ultimately, we wanted to make the tent even lighter and more livable, which meant going beyond simple updates or even major ones, like the changes to the Hubba Hubba™ HP. Here’s a brief look into our process of reinventing the Hubba Hubba.
At MSR, we actually build possible design solutions and test them ourselves, whether it means designing different pole configurations, moving guy points around or sewing in various types of vents to see how they affect the tensioning on the rainfly. Then we test the prototypes, not only in our onsite design lab but also in the field. Dale Karacostas, Director of MSR Shelter, has spent 30 days to date in the new MSR Hubba NX and Elixir tents, just to test them out.
But where does it all start? Read More →
A lot of outdoorsy folk can tell you where their WhisperLite has been – Yosemite, Canyonlands, Denali, Bryce – the list goes on and on. But how many of these people can tell you where their stove came from? Our new video answers that question in great detail. In this video we walk you through the making of a WhisperLite International stove, step by step, in our Seattle factory. The process starts with raw materials such as sheet metal, tubing and aluminum bar stock. These materials are machined and shaped into parts that are tested and hand-assembled to create each stove. The process is similar to that used on the first WhisperLite, manufactured back in 1984. Almost every MSR stove is manufactured in Seattle, including the Reactor, XGK-EX, SuperFly, DragonFly, WindPro II, and the three WhisperLite models.
Fall is here and nighttime temperatures are dropping in the regions where many of us live and play. This change in temperature brings up a question our tent team hears all the time: Why is the inside of my tent wet in the morning, even when it’s dry outside? The answer is phase change! This MSR video explains the phenomenon as we experience it in the backcountry. It also covers what you can do to reduce condensation in your tent. And for those of you who don’t take condensation seriously, trust us it can be in tents!
Fuel canisters are made of steel, which is recyclable as mixed metal. The valve includes parts made of plastic and rubber.
At MSR we get this question all the time: How do you recycle fuel canisters?
Isobutane canisters are made of painted steel and plastic valves. Technically they can be recycled as mixed metal. Unfortunately, the process is a lot more complicated than just throwing your spent canister in a bin. Fuel canisters can only be recycled in areas where mixed metal is accepted, and they can only be processed when properly prepared beforehand. Here’s how to make your fuel canister recyclable:
- Make sure the canister is totally empty. You should use all the gas for cooking – it’s better to burn the hydrocarbons than release them. Of all the stoves on the market, the Reactor is probably the best at using the last drop of fuel in the can.
- If you think there could be some gas left you can purge it by attaching your stove, inverting it, and opening the valve. This will allow any remaining gas to leave the canister. Make sure you’re clear of any potential flame or source of sparks while doing this.
- Once you’re sure the canister is empty, you need to puncture it so it meets recycling requirements. You don’t need a special tool to do this – just puncture it with a can opener or a sharp object like a screwdriver or an ice axe. Don’t use a saw because it can create sparks that will ignite remaining fuel. You don’t need to remove the valve to meet mixed metal requirements. Read More →

The Lunch Room (TLR): You have fire in your title. What exactly is your role?
DK: I’m responsible for overseeing strategy, product development, marketing and sales for stoves, cookware and fuel. I get to use my knowledge of combustion and stoves, and tap into my engineering background on a regular basis.
TLR: How long have you been doing this?
DK: I joined the company 14 years ago as a manufacturing engineer with the goal of moving into R&D. I came in with an engineering background, and a passion for climbing and mountaineering. It’s hard to find engineering jobs in the industry because once you’re in nobody leaves them. The manufacturing opportunity opened the door for me to eventually move into product development and management roles in filters, stoves, snowshoes and climbing gear.
