Bivvy Materials

[lamper]

All,

Looking to get a bivi bag to work with my Go-Lite Shangri-La 3

Now it doesnt need to be completely waterproof as it will be inside the tarp, but it does need to be breathable and keep the wind off - a bug net or hoop is a bonus.

I sleep quite hot and so I am worried about dampness and condensation on my down bag.

What is the breathability of

• Goretex
• eVent
• Epic
• Pertex

Bivi also should be pretty light so if you have any personally experience please let me know. I am currently looking at the following (depending on what I hear about fabrics)

• Mountain Equipment Ion - http://www.mountainequipment.co.uk/the_gear/tents_+_shelters/bivis/ion_bivi_-_biwaksack---375/
• Rab Ultra Bivi - http://www.rab.uk.com/equipment/bivvis/ultra_bivi---70/ - PERTEX QUANTUM
  
  
• Alpkit Hunka - http://www.alpkit.com/hunka/ - PU coated Nylon
  
  
• British Army Issue - Ebay - Goretex
  

Thanks in advance for your input.

I had a British Army bivi, got a hunka, sold the Army bivi. Decided I couldn't get on with the Hunka (too small/restrictive), sold it and bought another army bivi. The hunka's are light, but too small IMO. I expect the XL is better, but out of stock at the moment. I like the space in the army bivi (room for kit too), but at the expense of weight I guess.

Rab Survival zone or Alpkit Hunka should do the trick. I use a survival zone under my tarp and it has never let me down. Also it's light and cheap.

Yeah I was thinking this or the Hunka are the front line contenders. Whats the breathability like of Pertex Quantum?
