Sneak Peek – UF PRO’s Delta OL 3.0 Suit

Wearing comfortable clothing is essential when you want to stay focused, especially when operating outdoors in winter conditions with a full load-out, and the Delta OL 3.0 Jacket and Pant have been designed specifically with this in mind.

During activities in cold weather, the Delta OL 3.0 jacket will keep you protected against all kinds of cold weather hazards, offer you the necessary durability and most importantly, give you the comfort you need to focus on your tasking.

The Delta OL 3.0 jacket is due to its face material windproof and water-repellent. This means that the 2-layer ripstop laminate will stop wind-chill and also keep you dry during heavy snowfall and light drizzle.

A combination of G-Loft and WINDSTOPPER® means the Delta OL 3.0 uses the perfect technologies to protect you. The exceptional G-Loft thermal insulation created out of different hollow polyester fibres a 3D structure which can retain the maximum amount of dry air. This creates a warming thermal insulating layer between you and the cold environment. And the fibres keep their structure also when wet. Due to the so called “memory effect“, they always return to the original form, even after multiple washes and hard usage.

To keep your core warm and to give you extra movability in the arms area the jacket has two grades of thermal insulation. In the torso area it is lined with a 145 g/m² and in the sleeves with a 110 g/m² G-Loft insulation. Areas which are more prone to abrasion, like the elbows and the lower back area, are additionally reinforced with a 500 Denier Cordura® fabric.

The jacket offers in total 8 pockets, which allow you to stash most of the stuff you need within hands reach. Smaller gear can be stowed away in one of the 4 sleeve pockets. For bulkier gear you can use either one of the big front pockets or the two inner pockets. Due to the Delta OL 3.0 jacket’s anatomic cut, the jacket allows you freedom of movement, but at the same time it is tight enough so you can wear additional gear, like plate carriers or chest rigs over it.

The complementary Delta OL 3.0 pants are one of the very few thermal insulation pants on the market which offer a non-baggy cut, allowing you amazing movability and without compromise on thermal protection. Due to the special Flex/Zone construction and an integrated bi-elastic stretch part in the upper front and back, UF PRO can create anatomic fitted pants which follow all your moves and don’t compromise on thermal insulation protection.

The Delta OL 3.0 pants are thanks to their face fabric windproof and water-repellent. This means that the 2-layer ripstop laminate will stop wind-chill and also keep you dry during heavy snowfall and light drizzle. Just like the jacket they make use of G- Loft insulation and WINDSTOPPER® fabric to give optimal performance.

The pants are feature an adjustable waist, long YKK® water repellent side zips, belt loops and detachable suspenders; they also benefit from two fleece lined front pockets with YKK® water repellent zips, adjustable lower legs with boot hook, and Cordura® reinforcements in the knee and instep area.

If you need to be operating at the highest level in the worst winter conditions then the Delta OL 3.0 Jacket and Pant are the very tools for the job.

    If designed to be worn with gear (gear on top, which I think is a horrible idea), why the extra insulation on the torso? Gear on the torso makes you generate more heat (and sweat), and extremities are usually where cold weather first will have it’s effect, have less insulation.

    • Invictus says:

      If I had to guess, I’d say their designers wanted the warmth rating for standalone use, as well as sub-gear. The pitzips are cut pretty generously, to that end. Probably best to err on the side of warmth, in cold weather design.

      I wouldn’t want to be the designer who has to decide which armor carrier to pick as a pattern to remove the insulation underneath. And until we get something like a stillsuit, cold weather gear is always going to be a series of compromises.

      • Lasse says:

        I agree that it is a world of compromise, this is not up for discussion.

        However, considering that ~50% of your heat loss comes from the evaporation of sweat, then sweat should be considered the main thing to avoid. Therefor, the concept of wearing a puffy jacket under gear, is quite frankly a bad choice since you cannot rapidly adjust your layering which will result in more sweat once you go active. If I was the designer, I would make a garment that is designed to be worn over combat gear but still maintain access and is quick to don and doff. I have never worn a puffy while active, and I can’t remember seeing any of my peers do so either.

        I get that countries follow different doctrines, but I do believe us Norwegians got the whole cold weather science pretty locked in. It’s all available publicly, so if you want to do some reading to understand my point of view then go here: (injuries and personal clothing)

        • Dev says:

          Hmm. What you say make a lot of sense. I have never had the (mis)fortune of training for Arctic or extreme cold weather operations, but I recall seeing a lot of (mainly marketing though have to be said) material of soldiers in high alpine areas kitted out with plate carriers on top of insulated garments.

        • Dev says:

          That link was brilliant by the way thanks for sharing. Looks of good stuff in there.

        • Kemp says:

          Not to mention that all that kit will compress the insulation, making it both less effective AND less breathable.

  2. RgrBox says:

    I wonder when will companies stop putting those zippers to high up on the jacket. I want my pockets for my hands. I love my Atom Jacket. the pockets can be used comfortably.

    • Rod says:

      I don’t particularly like the high pockets either, but I do appreciate it for its intended design. If you’re wearing a pack with a hip belt it’s the only way to get in your pockets. And if you have normal pockets you can’t keep anything in them, as the contents will be pushed into your stomach.

    Face fabric should be made of nylon, not polyester

  4. Diddler says:

    Puffy jackets under plate carriers and ruck sacks, SBRs in wide open spaces, way-too-low leg holsters in the moutains? Looks like awesome cold weather gear, just now how I’d use it.

  5. Alan says:

    I like it.
