Mountain Hardwear's Hyperlamina series of synthetic bags combine the excellent Thermal Q insulation with ultralightweight fabrics and zoned filling to provide performance at low weight.

Mountain Hardwear says: Highest performance synthetic bag on the market. Thermally mapped insulation and half-length center zip maximize efficiency. Engineered to be the lightest and warmest synthetic bag on the market. Lamina™ construction welds the Thermal.Q® insulation to the shell and lining, eliminating the cold spots caused by traditional stitching.

By mapping different insulation weights throughout the top of the bag we are able to concentrate warmth where you need it most – around your core and feet. Thermal efficiency is optimized by a performance mummy-cut, face gasket and single center half zip.

The Hyperlamina Torch is a lightweight, synthetic sleeping bag ideal for trips where temperatures could reach -16°C. The bag boasts a better warmth to weight ratio than traditional synthetic fill bags thanks to the Lamina construction which welds the Thermal.Q insulation to the shell and lining, eliminating the cold spots caused by traditional stitching. Zoned insulation places additional insulation at your core and feet to get more warmth where you need it, without any unnecessary weight.

The center, half-length zipper saves weight, while maintaining the ability to vent the bag if you start to get too warm. The snug-fitting performance mummy cut is designed to maximize warmth while eliminating needless bulk and weight. When the night starts to get cold, fasten the face gasket and cinch down the tailored hood to block out the drafts and seal in the warmth.

EN13537:2012 - Look for the 2012 label for the most accurate rating; In 2012 the EN system of testing sleeping bags was re-vamped - the new testing procedures are more rigorous, producing more consistent results than previous tests. 2012 results tend to rate sleeping bags as poorer performing by a few degrees when compared to previous test results, even though the sleeping bag may be identical, or even better.

This means that comparison between an EN13537:2012 rated bag and an EN13537:2002 rated bag are particularly difficult - our advice is to use the new EN13537:2012 rating to compare with other bags who have also been rated in this way.

Perfect for Kilimanjaro

I bought a regular and a long for my daughter and myself on our recent Kilimanjaro climb. I'd previously used a Mountain Warehouse "Everest" down bag which was warm but did not wash well afterwards so I was looking for a synthetic bag to replace it. As our kit woul be carried by porters having a synthetic bag and therefore bulkier and heavier than a down bag didn't matter too much. At 1.7kg for the regular it's not *that* much more than a down bag providing similar warmth and we saved weight on the Exped mat.
The bag itself is nicely made, compresses quite well (I reckon it takes up about a third more than an equivalent down bag) and the only real gripe is that it's a little harder to get in and out of than a bag with a side zip. You have to shuffle in/out of it like you're in a sack race ! It's nicely warm with no cold spots and is reasonably wide at the shoulder. There are no draughts with the neck and front zip baffle. It comes with a compression sack (which we ditched in favour of a sea to summit event sack) as well as a big storage net bag.
The only real downside I can think is that the outer material is quite thin and one of us managed to get a slight nick in the material catching the zip in it.
