Care

 

Seam Sealing Your Tent
Please note that the nature of the lightweight UV30si fabric means that the seams can’t be sealed with normal seam tape. This means you will have to seam seal the following tents before their first use: Olympus, Minaret, Citadel, Macrolight, Sololight and Microlight. We supply a tube of SilNet with this product to do this – for instructions on how to apply this, please refer to the manual that comes with your tent. All other tents come fully seam sealed at the time of purchase

Cleaning Your Tent
You are best to clean your tent with a natural soap (non-detergent; e.g. pure soap, vegetable soap, Granger's Tent Clean or Lux Soap Flakes) and a soft-bristled brush. Rinse well and dry in a well-ventilated area out of direct sunlight.
 
Reproofing Your Fly
After washing your tent with a solution of Nikwax Tech Wash, we recommend that you reproof the tent fly with Nikwax Tent & Gear Proof.

Condensation
Condensation is an ever-present problem when you're trying to stay dry in the outdoors. You have probably experienced the same thing on a wet day when you have just climbed into the car and the windows seem to take forever to clear. In small tents, the problem is exactly the same and shows up as condensation on the inside of the fly.
Condensation is the result of atmospheric conditions, which we cannot prevent, but can only minimize with good design and an understanding of the factors, which can make the problem worse.
 
What factors will increase the amount of condensation? 
•    High moisture level inside the tent 
•    A big temperature difference between the warm air inside the tent and the cold outside 
•    Low ventilation to carry the moisture-laden air away 
•    Very waterproof tent material 
•    A high overall humidity 
 
During periods of high humidity, such as during rain, it can be impossible to remove or reduce condensation. In these conditions, even a high degree of ventilation can actually increase the condensation rather than reduce it. In dry snow conditions, the humidity is usually very low, which can help to minimize condensation.
The more effective barrier that the tent fly fabric provides to stop rain getting through, the worse the condensation problem will be. This puts our tent designers in a difficult position and they naturally tend to favour keeping the rain out.
 
Because we all have to live with condensation, Macpac tents are designed with a gap between the fly and the ground, as well as active ventilation systems, to reduce the amount of condensation forming.
 
What can you do to minimize condensation? 
•    Minimize the amount of moisture within the tent. 
•    Ensure that all available ventilation is used 
•    Pitch the tent to catch any available draft 
•    Leave damp items outside or in bags 
•    Dry the tent thoroughly between uses

Fabrics

UV30™ Fabric
Highly waterproof
The combination of lightness, strength and waterproofness makes UV30™ the premium performance fly fabric designed for use in severe cold, wet and windy conditions. UV30™ is proven as a real performer through constant testing and use in New Zealand's Southern Alps and damp Fiordland Valleys.

Composition
UV30™ is a 30-denier double rip-stop nylon fabric with a high thread count. It is waterproofed with multiple coats of silicone elastomer on both the inside and outside of the fabric.

Lightweight
The use of 30 denier nylon yarns in UV30™ fabric means it weighs in at less than 60g/m2 – it is a very lightweight tent fabric.

Strength
Using double ripstop nylon makes UV30™ very strong and the silicon coating on both sides of the fabric acts to increase the tear strength of UV30™. The silicon coating doesn't bind or lock the weave but allows a certain amount of give in the weave increasing its capacity to absorb tension. This means the fabric has significantly higher tear strength than a similarly constructed fabric with polyurethane coating. Furthermore, the coating is applied without the use of heat and therefore does not weaken the natural strength of the fabric. There's less chance of ripping your fly on that epic journey where a tent with a gaping gash will cost you safety and security.

UV resistant
The multiple silicon elastomer coating means the fabric maintains it strength when exposed to UV radiation over long periods. This will significantly extend the life of your tent when exposed to sunlight.

Waterproof
Testing of UV30™ (to British Standard 3424) found that UV30™ is waterproof to 3500mm of hydrostatic head – more than enough to keep out torrential downpours. The silicon elastomer coating creates a highly water-repellent finish that stimulates a high degree of water shedding and keeps you dry.

UV75™ Fabric
UV75™ is a durable fly fabric for those who do not require the extreme performance of UV30™. Used on all our adventure camping tents, UV75™ will provide weatherproof protection for trampers and campers seeking independence without wanting to head into severe climates and environments.

Composition
UV75™ is a 75 denier, single-ripstop polyester with a high thread-count. It has a silicone elastomer coating on the outside and polyurethane coating on the inside.

Strength
Ripstop threads and silicone coating on the outside increase tear resistance.

UV-Resistance
The polyester composition of UV75™ combined with the silicone elastomer coating make this fabric durably resistant to damage from UV radiation.

Waterproof
UV75™ is a weatherproof fabric with a hydrostatic head of 1500mm (to British Standard 3424); enough to keep you dry during prolonged rainfall. The silicone elastomer coating on the outside creates a highly water repellent finish that stimulates a high degree of water shedding.

Reflex® UV
Reflex® UV is formed by a nylon face fabric with a hydrophilic PU membrane. It offers plenty of protection with a hydrostatic head of 20,000mm while maintaining a very high level of breathability. Reflex UV is also very light weighing in at no more than 85gr/m2.

Torrentwear™ XP
Macpac tent floors are tough and waterproof. Torrentwear™ XP is a densely woven nylon with a polyurethane coating for maximum durability and outstanding waterproofness (hydrostatic head of 10,000mm).
Torrentwear™ XP weighs only 104 gr/m2 and provides an extremely high level of durability (abrasion and tear strength). The tent floor fabric wraps up the sides of the tent and all floor seams are sealed in our factory with special waterproof seam sealing tape.

Torrentwear™
Torrentwear™ is the classic version of our floor fabric: a nylon fabric with a robust Torrentwear™ coating for durability and outstanding waterproofness (hydrostatic head of 10,000mm). The fabric is heavier than Torrentwear™ XP, but offers the same durability for our tents in the touring range. 

Poles

Tent poles form an essential part of a tent. They have to be lightweight and strong; rigid enough to stabilise the tent, but also flexible enough to give in to pressure from high winds. They also need to have a certain recovery to 'bounce' back after being deformed.

DAC Featherlite SL 9.0mm and the 9.8mm
Creating the right tent pole means finding the right balance between all these different qualities. Constant research and testing makes DAC Featherlite poles among the best-balanced tent poles on the market. DAC Featherlite SL tent poles are made out of very high quality aluminium in a seamless extrusion process to maximise strength. Macpac uses DAC Featherlite SL 9.0mm and the 9.8mm poles according to the specific requirements for each tent.

9.5mm 7001-T6 alloy poles 
In our adventure touring tents we use 9.5mm 7001-T6 alloy poles that are coated with a tough, black finish. These poles are slightly heavier and have a softer temper than the DAC Featherlite poles.
