I have just acquired a pair of Colltex extreme climbing skins (the red ones) and a pair of the G3 Momix.  The plush on the Colltex is very directional; I can feel glide rubbing my hand down the skin and the abrasive quality when I rub the other.  On the other hand the G3 Momix feels virtually the same smoothness in both directions.  If I use my fingernails I can lift the plush on the Momix a little bit, but it has much less grip than the Colltex with a table top test.  The Momix also seems to have a much shorter plush.

Do you have any experience comparing the two head to head?  I like the G3 attachments and glue, but I'm concerned they won't' provide suitable traction.  Could the Colltex 100% mohair provide better traction?  I'm also concerned about the glue on the colltex as I heard that you have to keep them warm for the glue to work well.  

I've spent the past 12 years on G3 alpinists on various skis and wanted to get some better gliding skins to help save my hip flexors.

Any input appreciated.  

hello Mr. 2 wheeler. Different reviewers looked at different skins. I, Andrew, ran the Momixes for a season and a half and loved them. Great glide and weight--that was alway superb. Sometimes, in icy or hardpack conditions, particularly if the uptrack was steep, I found the Momixes slipped a little bit. My solution was chucking a pair of ski crampons in my bag. With this combo, you are unstoppable.

I would hesitate having the Momixes without crampons, as my only skin for a whole season. G3 has come out with a lightweight alpinist this year that lools pretty sweet. But we haven't tested 'em.

If you have both skin brands  to play with, take them both along with you on a tour one day. Nothing better than a real world comparo.

Hey 2Wheeler, this is what the reviewer for the Coltrex Skins has to say:

"I am still using the Coltrex and really like them. Not unlike the G3's (which I haven't used), they glide very well and provide good grip in most conditions. I have had some slippage in the right conditions, and I found on wet spring days they tend to get wetter than synthetic. But I don't have ski crampons and have still managed many a great day touring on them. Sorry, no direct comparison."

Thanks for the input gents, looking forward to more glide and less tired hip flexors with my mohair skins. Tried the G3s in some fresh and faceted snow the other day and they were fine.  Just waiting to try them out at Rogers Pass this weekend on some more polished and steep uptracks.  I may be making my own uptrack if the keener tracks are too steep.

The G3 Momix are on my new sidecountry set-up (Katana and Kingpins). Had them out for the weekend at Louise/Kicking Horse and they were a pleasure in the fresh/chopped powder and on the Louise frontside hardpack.  I was a little surprised how solid the bindings felt compared with regular pin bindings.   I might use the Coltex to replace and old set of Alpinists on my backountry setup (Praxis Protests and Plum guides).  We don't usually have too many warm wet days in this part of the Rockies!

If you're planning a big multiday powder tour I love the look of the newish Atomic skins... upcoming review?:
