After 7 trips and a total of 12 nights of wild-camping in the hills I concluded that this twist to my love of hill walking was not just a passing phase and I could justify getting some lighter kit to enhance the experience still further. Swapping out my petrol stove for a lightweight gas stove last year was a good move but inexpensive. A lighter tent which would meet all my requirements was to be a more significant investment.
These are my initial thoughts on the Hilleberg Enan, something which I see as a ‘Mark 2’ to the popular Akto. For those wanting to skip to the executive summary – after two ‘test nights’ it seems to be great tent for my needs:
- Lightweight (albeit not ultralight) – 1200 g
- Flysheet first pitching
- Good size inside, and it has just enough headroom
- Really quick and easy to pitch on your own (kind of important for a solo tent!) even in strong winds.
What is the space like inside?
Perfect for my needs. I am 5’ 11” and find the length of the inner tent around 6” longer than my absolute needs. If I have my feet all the way to one end, then the height over the inner tent above my face when sleeping is not claustrophobic. If you are much above 6’ that might be different. I can sit up at the highest point of the tent with about 1” above my head in my normal posture. If I sit bolt upright my head brushes the inner. The Terra Nova Laser is 2 cm taller.
There is space for a set of clothes, book, torch etc in the vertex next to the middle of my sleeping mat. Plenty for 1-2 night stop. The porch is excellent with plenty of room for my 55 L pack, boots and waterproofs in the fixed fly half and enough space to cook within the openable section. One great addition would be if I could figure a way to attach the door corner to a walking pole to stretch it out like a tarp. This is a nice feature of some Nordisk tents. I suspect something could be fashioned from a short length of climbing cord.
How does it handle the wind?
The Enan coped well with winds up to 40 mph in an exposed position. I have added two extra guys to the windward end for which there are fittings for this purpose. This helped make the fly tighter and provided reassurance for this life long tunnel tent sceptic. The tent flapped a bit, but the flysheet material does not ‘crinkle’ like a crisp packet. The benefits of silicone over PU I guess. I think this was probably the strongest winds to which I’d be keen to expose the tent. On reflection I do need to be aware that I’m used to using bombproof geodesic tents. That this single pole tunnel tent would best be pitched in the lea of a wall or a bank is the price to pay for the reduced weight. I reckon that’s fair enough.
How does it handle condensation?
Most Hilleberg tents are designed to be able to be used in snow with their flysheets coming right down to the ground. This reduces the ventilation between the fly and the inner tent and seems to lead to significant condensation for many people. So significant as to be ‘unworkable’ in a number of reported cases. So, for me at least, it was time to think about the science. According to a variety of sources, and depending on body weight and environmental factors, people respire between 300 – 500 ml of water over an eight hour period of sleep. If little or none of that water escapes the tent then that could become a lot of condensation. Also as the temperature drops overnight so will the dew point of the water laden air within the tent. Thus I reasoned, if you choose to sleep in a tent whose volume is very small, you are likely to end up with a condensation problem whatever the make / shape of the tent.
So, was the Enan likely to reduce this issue to an acceptable level? On paper Hilleberg looked likely to have resolved the issue and asking around proved that it was people with problems who had published their thoughts, a good number of long-term Akto users were quietly very happy with their tents. The secret to reducing condensation is to have a good number of air changes within the space. Good air circulation is promoted by having a cross flow of air, ideally from bottom to top rather than just from left to right. This is how sash windows are designed to work. Here Hilleberg have come up with an unusual but effective solution by including a mesh panel at both ends of the tent, the ends which should be aligned with the direction of the wind. [Also true of the Terra Nova Laser.]
Cunningly, these are steeper than vertical. Thus water from the fly will not run down them, nothing can pool on them either. Whilst wind blown rain will pass through them it is slowed down enough so that (in my experience) >>99% drops to the ground before it hits the inner tent. In my first pitch in an elevated exposed position, with winds of 40-50 mph and heavy rain I counted three drops of water on the inner tent behind the windward vent in the morning. No water actually came into the inner tent itself. There are rain covers you can put across the vents if the weather is really foul and thus is best done from outside the tent ahead of need, it’s very fiddly to do from inside the tent in the middle of the night.
On my first test night I had both vents open until around 0500 when I shut the windward one. Things were getting a little wild outside! In the morning the inside of the fly was completely dry. However the overnight temperature was a very mild 14 C. On my second test night I shut the windward vent from the outset and devised an effective and lightweight way to keep the top of the door open despite it’s design.
This is where Hilleberg may have missed a trick. The Akto has a small rain hood over the top of the door and a second zip allowing you to have a segment of the door open, not just a slit which is practice is pretty much held closed by the tension of the flysheet. But if a 10 g clothes peg can reduce the condensation I have to carry in a damp tent by 100’s grams it’s an excellent investment. After the second night which consisted of heavy rain, 20-30 mph winds and a minimum overnight temperature of 10 C I had just the lightest layer of condensation on the flysheet, an amount that anyone would consider acceptable.
With pubs and campsites to open from 4th July, I think I have the ideal tent to walk a five day section of Wainright’s Coast to Coast. Thanks to the Enan and an upgraded sleeping bag, my kit will be down by a whole kilo on what I’ve had until now, and at 10 kg (excluding food and water) this is around half the weight which I used to carry 30 years ago.
