For my last garden camp, I used the Valley and Peak Ultra Bivy with my X-Mid. As many of you will know, the X-Mid inner is all mesh, which is not always ideal in Europe in cold, wet and windy weather. One solution is to use a bivy inner like the Ultra Bivy. You can find some more pictures of my bivy and a description here: https://blogpackinglight.wordpress.com/2020/02/13/valley-peak-double-j-zip-ultra-bivy/
Installing the Ultra Bivy under the X-Mid fly is very easy. I found pegging the individual corners of the bivy rather than using cords to clip to the fly sheet gave a better pitch. I’ve added linelok 3’s at either end which helps with getting the right tension for the apex shock cord. It’s almost as if the Ultra Bivy was made for the X-Mid.
I’ve never used a bivy inner before so I was interested in how it would feel. The bivy itself is only big enough for a sleeping mat and sleeping bag/quilt with a little bit of storage at either end. The large double J zip means the whole roof can be opened up. I was glad of my mod to clip the door back which tidied away the large panel neatly (I’ll do a separate post on the tweaks that I’ve made). N.B. the picture below is from my original post and I have dispensed with the yellow cord on the corners.
With the roof open, the Ultra Bivy is more like a groundsheet tub than an inner. This means that gear needs to be stored in the porches. It’s worth having a small piece of groundsheet or polythene to put your rucksack and gear on. The fact that the X-Mid has two large porches means that there’s plenty of room to store and organise gear.
I was a bit concerned that it might feel claustrophobic when the roof/door was zipped up, but this wasn’t the case. I didn’t feel shut in and it was surprisingly easy to unzip the roof panel to sit up. I used my As Tucas Foratata quilt and found that using a quilt was good as when opening the roof, then sitting up, I could slide the quilt down to the end of the bivy without any material dragging on the ground in the porch. This might be more difficult with a conventional sleeping bag. Because the bivy is relatively narrow and enclosed, it is ideal to use with a quilt as there’s no chance of draughts under the edges.
I used the V&P hood, but didn’t attach it at the apex. This provided enough draught protection but also gave a bit more ventilation and felt less closed in. I’ve added some kamsnaps to the hood for ease of attachment (again, I’ll do a separate post on this). The roof pocket was great for small items like a pack of tissues and phone.
There’s not much else I can say. Overall, I’m really pleased with the Ultra Bivy. Given that there’s no solid inner option for the X-Mid (I’d still like one!), the Ultra Bivy is a good alternative and should work well in cold, wet and windy conditions, where a mesh inner is less comfortable.
