I have not had any issues with any of Thatchreeds gear (apart from some buckles that broke on a pack) and find them generally fair value for their price.
I review quite a bit of their kit in my mag columns and while they are not the top of the quality tree they are not top of the prices either.
No conection with the company except I get sent stuff to write about - including the bivi bag!
I've got to say, I have never looked at the bivvy bag in question, nor know anybody that has one.
That said, my experience of Thatchreed kit (mainly Webtex) has drawn me to one conclusion only- that it is absolutely shocking. At first glances, yes, it may seem reasonably durable. Maybe even after a couple of days use it still seems ok.
A few months down the line though it really shows its true colours- rucksack shoulder straps that have padding such poor quality that it goes completely flat. Stiching so bad that the straps fall of entirely, and rucksack lids remove themselves from the pack. Supposedly 1000d fabric quickly breaking down and becoming thin, flimsy, and losing its waterproof properties. Brittle buckles. Oh and for heavens sake don't make a foolish foray into their cheap Lowa boot imitations- so ill fitting its like wearing a pair of thin floppy leather wellies on your feet, just not as comfortable.
Mercifully, Ive not been victim of this myself, well not directly. But on more than one occasion I have had to carry part of someones kit because their webtex pack has catastrophically failed, and been slowed down because somebody thought they were getting a bargain buying webtex boots only to find they made a serious error later.
I don't mind the whole 'you get what you pay for' argument, but when the kit is specifically aimed at people that need and rely on robust equipment that will not fail (because if it does it could have particularly serious consequences), then I think the shoddy quality that Thatchreed peddles to gullible people is downright irresponsible.
Mercifully fewer and fewer serious users fall into their deceitful trap these days as horror stories become wider known....
I'm sure that now Ive had this rant, loads of people will post about what sterling service they have had from their thatchreed kit!
.........Just wondering what the breathability is like and if anyone has used one in proper, trying conditions?
