I'm a huge fan of Julbo above any other make of sunglasses however I can't give these the best marks. First off the size is really big! I have a big noggin and these were even big on me. The lenses were pretty clear however because they were big on me light would come in from the top corners creating a blueish halo against the lenses. The quality is great, and the optics are crystal clear when there is no halo. I would recommend getting the Dirt model as they wrap around your head better and are a bit smaller keeping the similar style.

I don't know where all these negative reviews are coming from... Perhaps improper use? I go canoeing and hiking regularly in the summers every year and my buddy always brings this filter. We have NEVER had a problem with it. There have been times where it became difficult to pump, at which point we back flushed it and WHAMO! back to normal. We now use the hyperflow gravity adapter kit and go through roughly 16-25 liters of water per trip, depending on the amount of people, if not more. We have still never had a problem. And just to show I'm not an MSR fanboy (really I ain't, i try and use the best gear possible regardless of brand), We have used the MSR mini works, Katadyn Pro, Katadyn hiker, Katadyn Vario dual (the worst out of the bunch) and the Katadyn pocket micro filter. What can I say my buddy has a filter fetish. In any case this one has performed the best and longest out of them all. Plus it packs pretty small and is relatively light.
I would say that the individuals who wrote these poor reviews either had defect products, or perhaps weren't backflushing enough. The only draw back to this product is that you have to backflush it often, but its worth it. If you care for the product as instructed it will not fail you.
4 out of 5 stars because of the constant flushing.

After much debate between the Copper Spur and the Hubba HP i decided to go with the Big Agnes. I was initially worried about about head room... this is a non-factor now. I am 6'1 195Lbs. and can sit up straight without hitting my head on the ceiling. Now this is not a review on performance yet as i just received it and set it up. I'll be testing it out next weekend on a hiking trip. However the inside is HUGE!!! or at least has the feel of it being big due to the tapered footprint of this tent... wide at the shoulders and tapers down at the feet. The little back door to access the rear vestibule is genius and was one of the biggest selling features to me. Materials seem extremely light yet durable... I'll write back at a later date to see how it actually performs in the field... By the way set up took me literally 3 minutes . this is tent setup without fly.
