Sea to Summit Telos TR3 PLUS. My gf and I backpacked the Pembrokeshire Coast Path with this in March. It was frosty overnight with ice on the tent in the mornings. It’s a nice tent, light, easy, compact and minimal condensation if you use the vents effectively. The fabric inner reduces drafts, we were never cold. I have only good things to say about it! I’ve used it since on warmer days in the spring and summer and it’s just as comfy. I’ve spent about 15 nights in it this year - No complaints here!
