Whilst I currently utilise a Sea To Summit Ultralight Insulated inflatable mat, and its super durable, I recently spent just over a year on one, residing in a campground in a Macpac Minaret tent, I can still remember the superior comfort offered up by my Exped Synmat 7
Exped seemed to go through some delamination issues some years back with multiple reports of mat failures, whilst people were on tour, in a local touring forum.
Having already utilised my Exped for a couple of extended tours, I was paranoid about the potential for catastrophic failure whilst out touring the back blocks of Western Australia.
I replaced it with the Sea2Summit mat whose durability is now for me unquestionable, but is no where, in my eyes, as comfort offering as my memory suggests the Synmat7 was.
Ive found myself too often awakened off the mat to be a true fan of my S2S mat, but after years of service, I sincerely appreciate it’s longevity.
If it makes any difference, I’m a side sleeper.
I’m too old and soft now to consider a closed cell mat.
