I recently purchased the Pinon Ivy bag for bike packing. I’ve used a few times now and found it to be a great part of a light weight sleep system. I’ve used it in the mountains and down on the flats in both mild and hot temperatures and it’s preformed wonderfully each time. A recent trip along a mosquito infested river kept me bite free and comfortable all night. The only time I’ve found the bag slightly uncomfortable was on a very hot night, with extremely high humidity and no breeze, I don’t expect any solution would work ‘well’ in those circumstances. The bag is hard wearing and light, easy to pack, takes up no room and keeps you comfortable.
