Outdoor Research Bug Bivy - Lightweight Camping Shelter for Backpacking

I'm not a weight weenie, but when I can reduce bulk [weight and volume], It's always good.I have a few O.R. items in my camping and outdoors gear list and I've always been pleased with them. That trend continues with this Bivy.The Bivy construction is very good. Stitching is well done and overall, I expect good reliability. The underneath is tough wearing and as I use a light weight groundsheet for an extra layer anyway.The pole is easily put in place once you find the little velcro entry on the side. There are marking to show you where to insert the pole.It packs away to a very small and manageable size.I'm ~6", ~100lb so I'm consider myself the larger side of the one size fits all chart. I was easily able to roll inside and I had plenty of head room. Access to the zip [door/entry] was easy and the zip operation was positive.This product does what it says and provides great protection against airborne and ground borne blood suckers. A colleague woke in the morning from his tent and upon checking himself, found two ticks on his upper body. We're pretty used to mozzies now and they are not disease carrying. Ticks are real threat however. Two ticks in the tent was somewhat of an exception in fairness [first time in many trips], though certainly not shocking. If I needed a case in point to justify my new bivy purchase, I had just been given one.I don't see any negatives to be honest. I used a Thermorest and Snugpak lite sleeping bag and everything worked well. OK, this is all light stuff.For instance, a blow up mattress or other luxury bedding may make the available space too little and defeat the point of this bivy.There is some room for some small items in the head area of the bivy [keys, phone, camera and the like]. Not enough for anything more than a small fanny pack or the like but again, storage is not what this product is about.I did not use the guy line or stake loops on the first night and had no problem. The delrin pole was standing up well. I did on the second and this helped the delrin pole remain upright better.I put in my larger 4 season bag [Mountain Hardware] just for a test and found it works well also.The purchase experience from Amazon was great. I needed the item fast and I was impressed with Amazon and their shipping partner choice. I live in EU.This solution would work well on an MTB / bike trips, hiking, fishing etc. If you need to go light, are in warm climates and need protection at night against bloodsucking bugs, this is certainly a product you should consider.
