I got a woodsman X and a 3/4 length uq, which I asked Mat to increase the length on, it's now more of 7/8 length. Excellent service really top guy and kit, used mine this weekend, temps down to 2 deg, stayed warm, even had to take layers off. Only issue I've noticed, and this is not related to Mat or gear quality, is uq suspension really benefits from the tri plates or mini crabs to increase the lift and prevent air gaps. Once dialled though, excellent nights sleep.
