In Testing

  • The jacket has an incredibly light feel to wear.  
  • Fit was good with the half-and-half elasticated cuffs, snug but not tight.
  • Hood doesn’t flap around when not in use, and is incredibly cosy when in use and pulled close with the hood drawstrings.
  • The draw cord around the bottom hem, a good feature too.
  • The extra material under the arms “did what it said on the tin” and there was no sign of arm lift affecting the hem of the jacket.
  • I have to say it totally kept me dry on some very wet running days recently. The breathability was impressive compared to other fully water proof  jackets I have worn too. No feeling of clamminess at all.

Highland Wear Test

I also wear tested the jacket on the hills and trails around Edinburgh, and also on some winter days up in the Highlands near Kintail.

First thing to say is that the breathability is excellent. Even running several miles on cold winter days in the hills, with a thin base layer and sometimes a thicker mid layer, it did not have that ‘clammy or toasty’ feeling you can get with some waterproof jackets when you have been out for a while.

Waterproofing was excellent, the equal of any lightweight jacket I have worn. Weight and lightweight are a trademark of all Montane products and I have to say you hardly feel you have jacket on!

Further Wear Testing

International Ultra runner William Sichel from Orkney had the opportunity to test the Montane Minimus Stretch Ultra Jacket for several hours of heavy rain during this year’s 3100 mile race in New York (the longest certified road race in the world).

“New York experiences extended torrential downpours during its notoriously hot and humid summers. The rain is unlike anything seen in the UK with regards to its severity, intensity and simply the volume of water that descends. Yes, it’s warm, but very difficult to cope with whilst running. My experience was that it kept the worst of the rain out, the taped seams worked, it was light in weight and roomy and quiet to run in with an attractive bright colour. I tested the smock version but my personal preference would be for the jacket style. The hood was convenient and neat fitting and the large pockets were useful.”

Observations from a regular customer of ours, Matt Holland:
“I have recently purchased the Montane Minimus Stretch Ultra Jacket and put it to the test against our finest Scottish weather recently at The Glencoe Mountain Marathon in torrential rain. Previously I had worn the OMM Kamleika waterproof, which I loved apart from the breathability. Despite my reservations before buying of its resistance to torrential weather, given its lightweight structure, it stood up to the weather amazingly well and more breathable than other jackets I’ve run in. I would thoroughly recommend this product.”


Montane have long had a reputation for producing quality lightweight products.
The Minimus Stretch Ultra Jacket certainly lives up to that reputation.
Simply put: one of the best lightweight waterproof jackets on the market for sure.
It comes highly recommended for anyone just wanting to keep dry on a short early morning run, or a long ultra distance trail race, or mountain marathon in the most inclement conditions.

Technical Terms

*What is a Hydrostatic head rating?
For a jacket to be considered fully waterproof it must be able to withstand the pressure of a column of water 1000mm high without leaking. This is classified as a hydrostatic head rating of 1000.The Montane Minimus Ultra Stretch jacket with its 2000 rating should deal with most European weather conditions.

**What is an MVTR rating?
MVTR stands for Moisture Vapor Transmission Rate. It measures the rate at which moisture permeates through a fabric measured in grams/meter/day. It is notoriously hard to measure accurately, so any rating should be treated as a guide. Similar to water proofing the higher the rating the more breathable your jacket is. For example 20,000 MVTR rating will be far more breathable than a 10,000 rating but not as breathable as a 30,0000. The Montane Minimus Stretch Ultra Jacket with its rating of 20,000 is eminently suitable for “moisture management” while out running in rainy and windy conditions – for short runs of a few kilometres to longer runs up to marathon trail events and beyond.
