Guardian Purifier

rated 5 of 5 stars Simply the best water filter in the world. I have used water filters for decades. My first one cracked when it froze. I have used two MSR MiniWorks with great results. It was great to be field repairable and field cleanable BUT filtering water was slow and required a lot of effort, usually at the end of a long hard day! Enter the MSR Guardian! Less than half the effort of the MiniWorks and at least twice the speed. For these two features alone this filter would be the winner but there is sooo much… Full review

Fuel Bottle Cap

rated 5 of 5 stars Great fuel cap...simple and effective. This is the stripped-down fuel cap for MSR bottles. It's lighter than the child-proof cap, without any mechanism to break. It does have a tiny bill one side meant to be used to pour fuel, but I would only use it for that purpose in an desperate situation. It doesn't produce a clean, neat stream. So, it's difficult not to spill fuel. The best use is simply sealing you fuel bottle when the pump is not in use, which it does very well. I have used one of these… Full review


rated 4 of 5 stars Fantastic tent for a 4-season camper not climbing to the peak of a snowy mountain. After much searching for the right combination in a 3P tent that can do almost everything a backpacking tent could be, the search can be declared to be over. The MSR Holler is a fantastic combination of high quality, lightweight materials, a very sturdy design for a 3-season (better than the Nemo Losi Storm we had prior to this that was supposed to be a 4-season), a simple setup, and a pretty well thought out organization/design.

WhisperLite Universal

rated 4 of 5 stars A replacement for my MSR Dragonfly multi wet fuel stove that was too heavy. This stove is a canister/white gas/kerosene/unleaded auto fuel stove. Using three different jets it can use four different fuels. I sold my too heavy but reliable MSR Dragonfly stove after two decades of use. It was THE best simmering wet fuel stove on the planet and could thus save fuel. The MSR Whisperlite Universal meets every camping requirement except the ability of wet fuel modes to simmer. It is "heavy" by UL standards… Full review


rated 4 of 5 stars Workhorse. I bought my first Whisperlite about 25 years ago. It does what I need it to do for long trips with several people at high altitude and in cold weather. A couple of years ago, the plastic pump housing broke while I was testing it for a multi-day trip in the Beartooths. I mailed it to MSR and they sent me a new pump no questions asked, and I received it on time for the trip. Now that's customer service! Full review
