User Review: Marmot Men's Trestles 15

This is actually a great bag.  I have had it now for 2 years and have used it extensively and it barely shows any wear.  I have used it in temp ranges from 15 degrees to 55 degrees and have never been uncomfortable.  

I love the fact that you can control the climate in the bag!  The one side you can zip the bag down a quarter way and the other side is a full zip.  When the temps are warmer, you can unzip both sides and fold the top back.  When the temps are colder you can zip it completely up and be comfortable.     

As far as getting cold, you have to take into consideration how you sleep normally.  If you sleep warm like I do, then a 15 degree bag will work down to 15 degrees and maybe lower depending on how you dress and if you buy a liner (a use a cotton Alps Mountaineering liner mostly to keep the inside of my bag from stinking and wearing out).  If you sleep cold (meaning that you need to wear extra covers) then you would be better off buying a zero degree bag.  Everybody sleeps at different temps and when buying a bag you must know how you sleep.

I have also read reviews on the zippers getting stuck.  This reviews usually come from those who do not know how to use a zipper in a bag.  I have never had any issues with the zipper!

In the end, this bag is warm and roomy and of very good quality.  I would recommend buying this bag (my dad also bought one this year after using mine for a cold weekend) to any one.  

Also, store your bag unrolled (in a storage bin or under your bed).  If you keep a bag rolled up, the insulation slowly decompresses over time and your bag will not keep you warm.  Even after 6 months, your bag will not be as efficient!
