The Primus Classic Trail finishes towards the middle of our fleet for a low price. While it isn't the lightest stove, it is lighter and more packable than several other stoves in our test. The large burner head means it works well with bigger pots and pans. If you're looking for a backcountry burner with the cooking performance of your stove at home, read on.

Our Analysis and Test Results
When our testers first took this stove out of the box, we were unimpressed. It has the look and feel of a canister stove from 30 years ago. We were surprised then, to get it out in the field and find that not only does it really throw some heat, but it also simmers well. Unlike the other small canister stoves in the test, it has a broad burner head which, while presenting some problems, nicely distributes heat around the bottom of a pot or pan, limiting hot spots.
When we first fired this stove up, we were very impressed by the flame and heat output. We were not surprised to find that it was one of the least fuel-efficient stoves in the review. It wasn't too bad in the no-wind test, but like some small canister stoves, it performed poorly in front of the fan. It burned a lot of fuel without achieving a rolling boil during the 2 - 4 mph wind test.
We suspect one of the reasons that our tested fuel efficiency was low is that the burner head is quite large on the Classic Trail, almost three times as big as some others and the largest in the test. Our tester backpacking pot is 7 inches in diameter, and so part of the flame inevitably licks up the side and heat is lost. While using this stove, a bigger pan is better. For users concerned with fuel efficiency, making sure that the flame does not go beyond the bottom of the pot is essential.
Weight is another metric where the Classic Trail lives up to its old school appearance. At 6.7 oz it is the heaviest small canister stove in our test. It is, however, much lighter than any of the liquid fuel stoves.
Though this could hardly be called a "small" canister stove, it is still reasonably packable. When we unboxed this stove, the control valve assembly was loose from the burned head. When installed, it makes the stove awkward to pack, but if removed after use the unit can easily fit in our 2.5-liter pot along with an 8oz fuel canister.
Low heat cooking is where the Classic Trail shines. The spectrum of flame control on this stove was possibly unparalleled in our test and reminded us more of our stove at home than something we'd carry into the backcountry. It was easier to simmer with this stove than with any of the liquid fuel stoves designed for simmering. The wide burner head distributes heat around the bottom of pots and pans much better than the laser focus of many of the other stoves in the test.
Ease Of Use
The Classic Trail has some features that make it quite easy to use. Because they don't fold up to get smaller, the large pot supports come to the middle of the burner head, so big and small pots are reassuringly stable. At 8 cm it's got a reasonably low center of gravity. While large pots are more stable on this stove than most, users should beware of mounting this burner to a 16 oz fuel canister. Doing so with a pot full of two or more liters would disrupt the stove's center of gravity and overcome the inherent stability of the pot supports.
It lacks in other areas. The small old-fashioned valve control knob is harder to find under the pot, especially under the larger pots and pans that suit this stove. We wish it had the modern wire control that most stoves in our test have. We also miss the piezo igniter found on many of the other stoves. These are the two features this stove lacks the most, and we think they would make the user experience just like the stove at home.
The Classic Trail put in a solid no-wind boil time, bringing 1 liter of water to boil in 4 minutes and 22 seconds.
Like most small canister stoves, it did not do well in the wind. In 30 minutes, it failed to boil 1 liter of water but made active bubbles on the bottom of the pot and brought the water temperature into the 170's F.
We do not recommend an aftermarket windscreen. Readers should be aware that Primus explicitly warns against this in the instructions and there is a risk that the canister could become dangerously hot and explode.
It's hard to find any quality piece of backpacking gear for this price, never mind something as important as a stove. The low price and reasonable (if sometimes dated) performance of the Classic Trail make it an excellent value. It's so inexpensive it could be a good choice for a home emergency kit or a backup stove for car camping.
While this stove wasn't perfect, it cooked well, and the price is pretty great. If weight and fuel efficiency aren't big concerns for you, but the cooking ability is, you may have just found your stove.
