The SF CHARGE trousers are a supremely resilient and versatile multi-functional utility trouser.



They’ve been hauled up some of the highest mountains in the world, rappelled down vertical cliffs and thrown out of planes at 14,000ft.  Featuring reinforced knee panels that utilise hexagonal woven Cordura® x Dyneema® fibres, this gives high tenacity resistance whilst maintaining elasticity for dynamic movements.  Bespoke trims have been meticulously selected and integrated into a highly flexible ergonomic cut, pockets have been designed for easy access whilst wearing a climbing harness.  We’ve incorporated all of the mission critical features you could need and eliminated any of the ones that could hold you back.  Nothing is left to chance; go-to, go-anywhere, go-everywhere, go-hard or go-home trousers.


  • Highly flexible ergonomic fit.
  • A 4-way stretch crotch and thigh panels for dynamic movements.
  • Hexagonal weave Cordura® x Dyneema® Manju fabric on the knee panels for enhanced tear and abrasion resistance.
  • Ergonomically design for climbing harness.
  • 2 side bellow dump pockets with velcro closure.
  • 2 side extendable velcro adjusters.
  • 2 front thigh internal pockets one with internal phone pouch.
  • 2 Hand pockets.

Customer reviews and ratings

  1. Josh Kind

    These trousers are absolute killer. The materials used are so hard wearing, yet it feels like you have nothing on. I’ve worn these a few times hiking and have been caught out in some heavy downpours. They actually do remarkably well of keeping the water out for a little bit, but also dry incredibly fast. The deep pockets are great for throwing items you need to hand fast in. I’ve worn many other branded hiking trousers, but I’ll be stopping with these ThruDark ones now.

  2. Stephen Leonard

    These are an essential bit of kit for me. I work as an outdoor guide in the Lake District so am exposed to all the elements on a daily basis. These are very comfy, functional and incredibly hard wearing. They hold up well in the rain and dry off in rapid fashion. They have good storage capability which is great for accessing essential kit when on the move. May even get a second pair to use when these are in the wash.

  3. Ernest Kim

    The SF Charge Trousers are perfect for any outdoor situation. I have already taken mine on hikes through the bush lands and mountains in Australia. Despite the trousers feeling unusually light in design, you don’t feel the cool outdoor weather. Usually after 20km hikes I’m sweating a lot, but the trousers help your legs breathe easy, and it drys very quickly after walking through rainfall. It has lots of hidden pockets so you can keep a lot of essentials on your that are within easy reach – overall, I’m very happy with my purchase of the Charge Trousers.

  4. Andy Burns

    Worn many makes/types of pants but these are way beyond next level. Ridiculously comfortable and durable. Each type of material is located with pin point accuracy. Wouldn’t wear any other pant now. 10/10

  5. Dan

    Perfect is an understatement. These trousers are unbelievable. Top quality from top to bottom

  6. Lee

    Absolute brilliant trousers hard wearing comfortable worth every penny I would ? recommend them

  7. Sarah Piper-Smith

    The SF Charge Trousers (Size Small) are absolutely perfect. As a female size 8-10 and a mere 5ft 2, I was a little unsure of whether these would fit as they are Unisex. I took the plunge and ordered them anyway and they fit perfectly. Comfortable and functional, these trousers stand up to the elements whilst walking, climbing or mountaineering in the harshest of conditions. A worthwhile investment, the SF Charge Trouser ticks all the boxes in terms of Comfort, Fit and Quality not to mention speedy delivery too! Thank you Thrudark. I will be back soon!

  8. Rich

    Waited ages for the restock and could not be happier, quality and fit is excellent, just like my old crye pants but in a more civilian looking colour and without the plastic knees. Light and comfy, great for any outdoor activity.
    more colours would definitely be a winner!

  9. Christopher Dunkin

    I have the unreinforced knee version, however, still consider them to be a hard-wearing and essential piece of kit for me when hiking or training in the hills or mountains. They are very lightweight, but durable all the same. I would strongly recommend these to anyone looking to get a new hiking trouser that will no doubt perform well in whatever environment you are in!

  10. Andrew Button

    The quality is superb, you know straight away as soon as you take them out of the bag. I bought the SF hoodie too, and then I’ve been back again for more. Highly impressive gear – well done.

  11. Dylan Samuel

    Well what can I say, I just reviewed my order of the Charge trousers in a size S and I am seriously impressed. I own a few different pairs of trousers for hiking and all things but these are easily the best. I was unsure if they’d fit due to my height but they fit perfectly and they are by far the most comfortable I’ve tried. I also love the boot hook and ankle buttons as a nice addition. The pockets are also great and well placed for easy reach. All in all a great pair of trousers that I highly recommend.

  12. Carl McCracken

    I’ve bought a few thrudark products over the last few months and every single bit has been FANTASTIC! These trousers are my latest requisition and once again they do not! Disappoint. Very comfortable good stretch in the material all round great bit of kit!
    If you are thinking of buying them and thinking 🤔 mmm just DO IT! they will not let you down….

  13. Ahad Owji

    I like to wear army pants and I have so many different pants that is one is the best beautiful gorgeous perfect fit army pants I ever had and I love it

  14. Daniel Abbey

    Wow! Had a fair few bits from the guys at Thrudark and the quality and thought of every product is next to none. Buy cheap buy twice

  15. Darrell Beazer

    Superb activity trouser. Tough, comfortable and fit for purpose. Purchased obsidian black, now I “need” a pair in MULTICAM. As with all THRUDARK gear, don’t waste time thinking about it, buy it. If you hesitate, your too late. Proud to support this future iconic British brand. Endure through adversity all day long!!!

  16. David Labshere

    Being in the search and rescue field and relying on my clothing to perform is key! Let me tell you these pants are second to none! The fit is superb, the quality and finish is there and the design while obviously super cool looking is also extremely functional and well thought out! The only question you should be asking yourself is what color to buy!

  17. Chris

    I have now had the sf charge pants for 2 years. I wear them 7 days a week for hiking and work. They are literally unstoppable, the material on each section is still in fantastic condition. I Chuck them in the washing machine most nights after I have worn them. Hang them in the airing cupboard, they are dry and ready to go the next day. Can’t recommend them enough. A fantastic investment if you only except the best.

  18. Pete

    Awsome outdoor trousers! light and stretchy in all the right places for a very comfortable / unrestricted fit. All elements are are well placed, clearly a lot of thought has gone into these, e.g: map pockets fall in line for a hand reaching down etc. I’d give a ‘perfect’ if there were more sizes available.. small fitted my waist and legs perfectly but were just too short so had to choose the medium instead.

  19. Andre

    The best utility trousers I’ve owned. Fast drying, hard wearing and easy to adjust for any size or situation. The hidden loops and boot attachments make these perfect for winter walking as well.

  20. Andrew Bull

    Fancied a change from my Montane Terra and Super Terra trousers for hill climbs. These may cost a little more but are every bit as good and some additional nice touches like the double waist button and side adjusters. Overall a very functional trousers that can be thrown at the mountains would highly recommend

  21. Joseph Mcginley

    My new TD Charge Trousers arrived and they are an absolutely awesome piece of kit and the quality just shines through.
    My collection of TD products is fast growing from jackets, hoodies, fleeces to the force range and these are a very very welcome addition.
    All of the TD kit looks fantastic too from outdoor use to everyday wear.
    Honestly cannot recommend ThruDark enough.
    Thank you.

  22. Russ Price

  23. Owen Jones
