This stove is great. I’ve been using it for a few months now. It weighs almost nothing and performs quite well boiling 2 cups of water in under 3 minutes. Plus, it’s cheap. If it isn’t for you, then you’re only out $20.

For 3 season, mostly fair weather, UK & European camping I am totally happy using my Duplex, so I would go with that. You just have to accept that condensation is a mostly daily management issue - no biggie!

I would look at halving your combined rainwear weight - the Montbell Versalite jacket and pants are good options that will get you under 300g for the both of them.

I would also look at the 2018/19 Montbell Exlite Anorak (if you can still get hold of one) - despite having a hood it is lighter than the Ghost Whisperer hoodless and it’s warmer by most accounts than the hooded GW too.

Personally I would go with an Evernew 900ml tall pot with lid at 95g (lighter than the Toaks and you can boil enough for 2 people’s dehydrated meals when you need to). I would also go against this sub’s Windmaster-love and choose instead a Firemaple stove for half the weight, or even a BRS at 1/4 the weight. There are lighter ways to master the wind than an 85g stove! (Use your tent vestibule or arrange your pack and some rocks as a wind-break)

Edit: if you are interested in the Nitecore NU25 you can do a version of the Litesmith Mod yourself, as per this video:

For your stove, I would swap out the Pocket Rocket for the BRS 3000 titanium stove. I've used this stove for almost a year of casual backpacking and my buddy has used hers for almost a year of hard use (almost every day for 3 months). I love this stove! Price:$13-$20 on Amazon. Weight saved: 2oz

Definately use the smaller canister for your fuel. I went on a 6 day trip where I cooked breakfast and dinner every day, and I had fuel left over at the end of it.

Check out the Yama Mountain Gear pogies. They are cheap, and are definately gonna ventilate better than the rain mitts. (I've never used them, but I'm gonna get some)

The only other thing I might suggest would be to use the Anker 1300. You'd gain a little weight, but it gives you an extra phone charge. This is really only necessary if you'll be using your phone for maps or pictures.

The Jetboil is a very popular stove, partly because of the convenience of having the stove attached to the pot, but also because it is very efficient; the pot has a built in heat exchanger which means you need less fuel to heat water. The cons are that as a unit, it is relatively heavy, and it is also relatively expensive.

If you want something a little lighter, a little less bulky and a little cheaper, you can pick up a MSR Pocket Rocket 2 stove and a generic 1L anodized aluminum pot. It's going to be lighter than the Jetboil, and thanks to the cheaper pot, cost less... but you're losing the heat exchanger so it's not as efficient. It will take a bit more fuel each time to heat water, which means you will have to carry a bit more weight in fuel... but unless you're mountaineering it's probably not a big deal. And of course the pot is not attached to the stove.

Now, instead of the relatively expensive MSR PR2, you can go a little cheaper on the stove with the Etekcity stove or the BRS3000T. I haven't tried the Etekcity stove but a lot of people like it. I've got a BRS and it's a nice little stove, extremely lightweight... but it's so small I'd be wary of leaving a big pot full of water on it unattended. It's good for heating water, but it's not great for actually cooking. The MSR PR2 is much better for actually cooking since it's a bigger stove with better pot supports.

There are other stove/pot/heat exchanger options which are just as bulkly/costly as the Jetboil, like the MSR Windburner and the Fire-Maple FMS X-2 if you're really looking for something just like the Jetboil. But most backpackers generally go with something like the MSR PR2 or Etekcity or other small canister stove and a lightweight pot.

It's a super active sub, and while you say ultra light isn't a necessity, there's a ton of good reviews and pack loadouts you can check out. I recently picked up SnowPeak LightMax.. Others have been using the cheap BRS-3000T

I have a BRS stove. SUPER light weight and CHEAP!

Mug + cone + wood burning insert + esbit holder + baking pan + remote alcohol stove + mini bic lighter + tinder = 10.2 oz and it ALL fits inside the can (yep, all at the same time)


Yes, all up its pretty heavy but you’ll almost never need or want to have all the options on a single trip but you could. More importantly, with this one kit you can adapt for a trip in any environment with any fuel and you can bake stuff in it too

BONUS!
this mug will also fit a BRS 3000T stove, bic lighter, and a 100g butane canister inside (but not at the same time as all the other stuff)
