OMM Sleep Suit | Review

The innovative sleep suit from OMM provides warmth and convenience for the outdoor enthusiast

This has to be the quirkiest item of this year’s Outdoors Magic 100, maybe even of all the 100s we’ve published over the years. That said, we can definitely understand the logic behind it.

The OMM are arguably best known for the challenge they’ve organised since 1967, the Original Mountain Marathon. For this, competitors must spend two days running and navigating between checkpoints spread across an entire mountain range, all the while carrying the kit needed for a camp out overnight.

It’s a demanding event that rewards those who are able to tolerate a minimalist approach, and that’s where the inspiration for this system comes from.

We’ve already seen the Mountain Raid PA 1.0 Sleep System where a half sleeping bag combines with a jacket, but the British brand have taken things one step further now by adapting the half bag so that it can turn into a pair of warm trousers.

“It strikes the right balance between night time comfort and comfort in the day.”

When you’ve been running for a day and want to relax and cook some grub outside of your tent or in the porch without getting too cold, this jacket and trousers will do the job perfectly. Then, when it’s time for bed, all you need to do is attach the trousers and jacket together via a set of press studs, unzip each trouser leg then zip them both together before attaching the sleeping bag end. Et voila! You’ve got yourself a complete sleeping bag.

Now this isn’t going to give you a cosy luxurious sleep, but it’ll give just enough comfort to get you well rested over a mild night. The idea is that it helps you to strike the right balance between night time comfort and comfort in the day due to a lighter load to carry and run with.

The trousers and the Mountain Raid jacket, one of the OMM’s bestselling items, both contain PrimaLoft Gold insulation. We’ve tried this synthetic fill out in loads of different jackets over the last couple of years and we can certainly vouch for it as not only does it have an excellent warmth-to-weight ratio but it will continue to insulate even when it gets wet.

This might be made with the Original Mountain Marathon event in mind, but we’d say it would serve you really well if you’re going hiking in a hot place with mild nights and don’t want to be carrying too much on your back.

The system weighs 745g altogether, which is crazily light considering what it will cover you for, and it should be released just in time for the OMM’s 51st event in October, which will be held in a yet to be revealed location somewhere in the South West. If you’re going, expect to see a few people sporting this unusual get-up!

Tester’s Verdict

“At the time of writing, it’s mid Spring and the nights are still cold – too cold to have the courage to get out and try this, anyway. I’ve had experience with it in the day though, mainly before and after some of the running races I’ve taken part in recently. Both the jacket and trousers are really snug, and the PrimaLoft Gold warms you up very quickly. Converting the jacket and trousers into the sleeping bag is quite quick and simple after your first time figuring it out, and once you’re in, it’s quite a close fit but one that I found to be tolerable.” – Will Renwick, editor of Outdoors Magic.
