Trailstar Inners - Protection vs Practicality

New member and first time poster, hoping for advice from the experienced members on the site.

Having had an MSR Hubba Hubba NX blown down around me in a gale on a summit in Wicklow last year, and having previously used a flat tarp, I invested in a Trailstar, which I love.

I've used it over the winter, getting used to various pitches, including low for protection in high winds. I modified a polycryo sheet, strengthening the corners with duct tape, so I could stake it out as a groundsheet. This, used with an army bivy bag (heavy but very spacious) has given me excellent protection against the elements, ground water and from ticks.

However, as we all know we're entering the dreaded midge season. In Ireland, they're almost as bad as in Scotland.

So, I think I need some midge (and tick) protection, but I'm struggling to decide between a couple of different options, taking into account weight, cost, liveability and protection. Apart from helping to keep the midges at bay, I'm thinking some type of inner, with a bathtub floor, will also allow me to dispense with the bivy bag, saving a considerable amount of weight.

Firstly, there's the MLD Trailstar Inner itself, which gives you a space to retreat to when the midges are driving you mad and looks quite liveable in. Expensive, and I'll probably have to wait 4-6 weeks for delivery. As a cheaper, but possibly not much quicker alterative, I've been looking on aliexpress. If anyone has one, do any of these, such as the one linked below, work in a Trailstar and offer midge protection, or are they just for good for mozzies?

Alternatively, I could splash some cash on MLD's Bug Bivy 2. This option is also expensive (like everything from MLD, but you pay for quality), seems to offer bomber protection from the midges, but provides a very small space. It seems only for sleeping in, so I don't think you could sit up in it, and it might not be practical to spend much non sleeping time in. What it does seem to offer, however, is the ability to climb in at the top, and then hook the mesh up above you, which seems more useful than the full inner when you want to pitch low. It also offers splash protection and protection from the wind, but is this overkill anyway with the Trailstar pitched down low, with a small door? Importantly, it's lighter that the larger inner option. I'm also thinking, I'd be more likely to use this in stand alone configuration without the tarp, when there's little chance of rain.

I appreciate that there's no perfect solution here and that it's really personal preference. But if anyone can share experiences of either of those options, or can recommend any other midge protection options for use with the Trailstar, I'd appreciate it.

I don't have a trailstar, though I'm aware a number of folk on here do, so hopefully they'll chip in with their inner suggestions soon. I have been searching Ali for an inner to go under a flat tarp, though, and I wonder if the Lanshan 1 inner may fit a little better than the one you linked to - it's a little bit lower, shorter, and more triangular in footprint:

The Ali inners do fit the TS. Depending on the height of the pitch will depend on how well they fit. The J zip inner fits better IMO than the T zip. That said I have modified the top apex of the T zip version to fit for a couple of mates.

Basically, if you fold over the apex around 5-8 inches depending on TS height you can pull it tight.

There will obviously be dead space behind the inner if you put it at the back but they work just as well with one end towards the door too.

Welcome to the forum John

Happy with my MLD inner, even without the Trailstar on a hot buggy night.
It was expensive but it is tailored to fit and can be rotated so you do not have to sleep behind the pole.

is the not the same shape as the Ali express inner? Not the one above but there is also another with a more shaped one like yours

Welcome John. I just moved to Wicklow so would love some suggestions for hiking in the mountains here ;)

If you want something you can sit up in (essential with lots of midges) then a bivy wont work out.

No specific recommendations, but check eBay and the Facebook gear swap pages for second hand MLD stuff (popular enough in the UK that they’re often available second hand) or some of the ookworks stuff (no longer in business, but they made aftermarket inners of apparently high quality and sometimes better design than the MLD stuff - Eg solid or semi solid inners for trailstars).

I'm new to this Trailstar ownership but have set it up a fair few times and slept in it in the garden a handful of times. I've taken advice from here and elsewhere and have used things that I've either bought to try with it or had already bought to use in other shelters.

I have this Lanshan 1 4 season inner that fits fine. I had to add corner struts to make them stand up properly. It fits fine at the back or side of the shelter.

I've also recently bought a Borah ultralight bivy as an alternative.

Many long term users of the Trailstar, including Chris Townsend (TGO gear editor) don't bother with an inner, using just a bit of Tyvek or Polycro. I have an 80 x 210 bathtub that I got from Aliexpress that fits nicely.

I'll measure the sides of my Oook in a bit and post for you if you like

EDIT, here you go. Hand written numbers in cm are from my Oooknest. Diagram and printed numbers from MLD site.

@Dave V i should've pointed out my thumbnail is from Oookworks, could have saved you some measuring but they differ slightly, yours must be real world dimensions :thumbsup:

Heres the 2Oookstar floor plan should you fancy making me one? ;) No-one else seems bothered about making them. Anything on Ali?

There's an Oookworks bathtub on Ebay at the moment that looks more like trailstar shape than hex, although camera focal lengths can be deceptive. Maybe worth an offer under the asking price if he comes back with the right measurements.
https://www.ebay.co.uk/itm/GoLite-o...Oookworks-3-4-size-bathtub-floor/283860791789

It looks odd because each end is different length. But it's not a TrailStar oooktub.

Sean used to do an asymmetric hex oooktub. One end was a full side the other a half side (like a "normal" hex half tub) . Gives a little extra length for taller people. IIRC that shape footprint was originally designed at request of Tracksterman.

@Mole Ah yes, I see now it has an extra apex over the diagram @Dave V posted earlier, so it must be a Hex tub, with the foreshortening caused by a wide angle camera lens making the ends appear more 'pentagonal' than parallel. I have an Oooknest with this footprint. It's 90" along the front, and I love it. :biggrin:

Thank you all for the very helpful information.

I'm tempted to take a punt on the Lansham 1 4 Season Inner, with the J zip. At the price it seems a very good deal.

The extra space over the bivy seals the deal.

Nevis, I'm from Dublin, but down in Cork for the moment.

oreocereus. If you're new to the Wicklow Mountains I'd spend some time on Lugnaquilla. Numerous ways to the summit and with varying weather conditions you'll get plenty of variety. The summit is a large plateaux, so when covered by cloud (which it usually is) a little bit of care is needed when navving, particularly coming off the summit. You'll find the hills in Wicklow a little less crowded than some in the UK (apart from the more remote parts of Scotland that is), especially during the week where you might meet nobody on lugnaquilla all day.

Think we might have to organise a mini meet with the three of us when this is all over, maybe wicklow way :)

Not that it will help you,I started with a piece of poly floor back in 2011 when I bought my first one,moved on and bought a tub floor ,then a bivy bag( Mld one) then an Alli inner now the Mld inner..all work but have diff limitations ..tend to use an inner these days,not sure if that’s just a habitat I’ve pucked up..Valley and peak do a bivy that might give you more room if your not wanting to go to a full inner ?

I’ve used the TS with polycro & Tyvek ground sheets, MLD & MYO bivi’s & a Bearpaws TS inner, as @Munro277 says they’ve all got their advantages & disadvantages.
The TS has gone to another home but if I was tempted again, I think I’d go for an AliExpress 4 Season inner (midge & draft protection), increasing mesh area is a simpler MYO job than adding draft walls to a complete mesh nest. The nest would preferably have corner struts so that the bathtub could be used without hooking up to peak (warm but no midge). I’d also be looking for it to be a quite a small footprint, say 2100 long * 700 to 800 wide & 1200 high, just sufficient to sleep/ eat in, J zip would be fine but could live with a T zip.

Thanks for the future information all. Settled now on getting an inner, I think. Whiteburn, do you mind me asking if there's a reason you'd go for the Ali 4 Season inner, over the MLD version, apart from the obvious price difference that is :). Is it the increased draft protection at the sides, with the ability to add mesh? How useful is the added protection in winter? It was thinking about this possible advantage that had me thinking about the MLD Bug Bivy 2 in the first instance.

I think the Lanshan 1 inner looks a great option if it fits, has the bathtub floor which will increase space over the head.

I have a 4 season version and it fits just fine. If I have pole low I just gather up the apex and put a loop around it as shown in @Robin s Gromit it's the wrong inner thread.

I modified it with carbon fibre kite struts at the corners to make the bath-tub stand up nicely. I'll take some pics next time I have it up.

ADDED: This is the one I got. https://www.aliexpress.com/item/4000127835327.html

I was thinking in the main about draft protection & in the winter stops snow blowing in.
The Bearpaw TS inner which I used had 30cm draft walls above the bathtub which was a reasonable compromise but there's only a limited number of folk produce anything like that. IMO the specifically design TS inners have a lot of waisted space (for me) which adds up to an increase in weight & more space to chase the uninvited midge around at bed time.
With a solid walled nest it's easy to add more mesh, put simply: pin no-see-um mesh over the area you want, run a sewing machine around then cut out the solid fabric about 10 - 15mm from the stitch line, roll the edge over & stitch down.

Thanks Whiteburn. I can see the advantages of the solid wall option if you might want to modify the inner. I'm impressed by the ability to take out the sewing machine to improve on a factory made product. Looking at the forum generally, I can see that a few folk on here make their own kit, or modify stuff they've bought.
