The Novel Msr Gas Canister

In conjunction amongst the liberate of the new, lighter 1.0L Reactor stove, MSR has changed the format of their 4 ounce (113g) class gas canisters.  Note the emphasis on the discussion "class."  We'll render to that inwards a minute.

The novel 3.9 oz/110g MSR gas canister

Yes, I'm writing a postal service most the shape of a gas canister.  :)  But I think this is genuinely news, in addition to expert intelligence at that.  For some time, MSR, which has the best mutual frigidness conditions gas available (at to the lowest degree inwards the USA market), has made a big, ungainly 4 oz/113g canister.

Now, this is non to criticize MSR.  I think MSR was really nobly trying to furnish improve service to their customers.  The wider 108mm diameter MSR canister was clearly to a greater extent than stable than the 90mm manufacture standard.  But amongst the advent of readily available canister stands ("legs"), such stability is no longer in addition to hence much a concern.

Now that MSR has accepted the 90mm manufacture standard, I tin forcefulness out purchase whatever 4 ounce class of canister in addition to know precisely inwards which pots it volition gibe in addition to which it won't.  The guess run in addition to having to shout back which is which is gone.

MSR in addition to Jetboil, instantly the same diameter (90mm)

Lighter Weight
In addition, the novel 4 ounce class canister is lighter for the total of gas it contains.  The one-time canisters weighed 8.6oz/244g.  The novel canisters weigh 7.4oz/211g -- for basically the same total of gas.  More gas per unit of measurement of weight?  That's pretty squeamish if you lot inquire me, in addition to I direct maintain no objection whatsoever to saving an ounce inwards weight per canister.

MSR, Snow Peak, Optimus, in addition to Jetboil 4 ounce class canisters instantly all direct maintain the same diameter (90mm)

Now, banker's complaint my emphasis on the discussion "class" when I nation 4 ounce class.   That's because the total of gas inwards canister varies a fleck build yesteryear brand.  Jetboil for illustration contains 100g, in addition to the one-time MSR canister contained 113g (exactly 4 oz).  With the change, MSR, Optimus, in addition to Snow Peak volition all uniformly direct maintain 110g (3.9 oz) of gas.  Jetboil is the outlier amongst solely 100g.  I figure a 110g canister volition final most v days for a somebody who is conservative in addition to doing elementary cooking inwards expert conditions or iii days for 2 people.  For tougher conditions or to a greater extent than complex cooking, you'll direct maintain to convey to a greater extent than gas of course, specially if you're melting snow.

The novel 4 ounce degree canister genuinely contains 110g (3.9oz) instead of 113g (4.0oz).  Influenza A virus subtype H5N1 3g difference?  No large deal.

MSR has likewise printed the gross (total) weight on the canister (7.4oz/211g), which is handy.

The Fuel Gauge
But what the heck are those piddling markings on the canister to the left of the weight?

The "fuel gauge" on the side of the novel MSR canister

Interestingly, they're a form of fuel gauge.  When the canister is full, it volition float depression inwards water.  When the canister is empty, it volition float high inwards water.  Out on the trail, all you lot direct maintain to create is driblet your fuel canister inwards a bowl or pot of water, in addition to wherever the waterline hits on the "fuel gauge" is to a greater extent than or less how much fuel you've got left inwards your canister.  Pretty cool -- in addition to for zero weight penalty.

I asked my contacts at MSR where they had gotten the idea, in addition to they told me that it was from my article inwards Seattle Backpacker's Magazine, How Much Gas Do I Have Left?  Yes, of course of report it's flattering to me that a major stove companionship adopted my idea, but think most what this genuinely means:  MSR is listening.  I for ane direct maintain been really impressed yesteryear what's been coming out of MSR inwards the final one-half dozen years.  They're genuinely paying attending to what the backpacking community wants, fifty-fifty to the signal of minor details similar this.  I incertitude that MSR volition live on making piles of coin on this "fuel gauge."  It's simply role of MSR's mental attitude of fantabulous client service.  Good work, MSR.

So, let's see:  More packable, to a greater extent than gas for the weight, and a elementary silent effective way to tell how much fuel I've got when I'm out on the trail?  What's non to like?  The novel MSR canister:  I welcome it.

Thank you lot for joining me on some other Adventure inwards Stoving,
