Macpac, that glorious Kiwi brand, has gone through some major organisational changes of late.
That has resulted in several new products focusing (it seems to me) on new materials. As well as the new eVent jackets and pants , there is an extensive range of Merino clothing (looks like a reduced range of Interwool,that is Merino on the inside and synthetic on the outside) but most important of all (well, only for me...) is the new tent line up.
There is only one new backpacking model, the Macrolite, a freestanding minimalistic 2 person 2 wall tent.
Not that light at 2kg but could be a good option for areas where space is at a premium and a dry set up (fly first) is preferred.
The others have shed some considerable weight by switching to silnylon. That should be good news particularly for UK (as well as Kiwis and Taswegians) users where an integral pitch is preferred (rain in summer is a bit warmer there but still wet) .
So the Microlite (single hoop ,one person) is now below 1.5kg (3 lbs) , the Minaret , a smallish but very well designed (IMHO) tunnell tent , is now just over 2 kg (4.6 lbs competing with the Nallo 2) and the favourite by rough weather aficionados , the venerable Olympus is almost light,for what it is, at 2.8kg (6.1 lbs) .
The Olympus is a 3 pole tunnel tent that by design can shed snow better than many other tunnel tents (again in my view,but has many fans too)
The weight savings has come about with the introduction of silnylon. UV30 PU (seam sealed) for the Hemisphere ( a bombshelter...) UV30 SI for the rest (you seal them) . Note that the lighter version still has a waterhead of 3000mm .
When comparing weights consider the emphasis by Macpac in weather protection, particularly wind and rain.
I have no connections with Macpac, but I am a Kiwi after all...
