I have had the Trinity Maternity Hiking Pant in my possession since the beginning of my pregnancy. And while I’m almost eight weeks postpartum, I have waited until now to post a review because these pants, like many products from Mountain Mama, are made to be worn before, during and after pregnancy. I thought I’d put that claim to the test.

Hiking is pretty much my favourite thing to do on this planet, so I was excited to have a hiking pant. As it turned out though, my body was just not a great match for these pants in particular. The Trinity Maternity Hiking Pants have many great qualities which I’ll outline below. But, for 5’6″ I have a short torso and long legs and the fit of these pants made them ride up quite uncomfortably both during and after my pregnancy. No doubt, they would be a great fit on some body types!

So, “fit” aside, here’s a bit more about the features:


  • The optional lengths (capri and shorts) hit the leg at just the right place for me (shorts aren’t too short like many convertible hiking pants), and the zip-off and button-up features are easy to use.
  • The Durable Water Repellent (DWR) coating kept the pants from absorbing water in a light rain, and the durability of the pants helped them stand up to some harsher conditions one sees on a hike. We generally see cooler temperatures here in the Rockies, so the weight of the pants was just right.
  • The cargo pocket is at the perfect height for reaching in.

  • The material is obviously very durable but comes off as quite stiff (this may also be due to the DWR coating). I am a big fan of Prana’s Monarch Convertible pants, which are quite tough yet flexible, so this was my basis of comparison.
  • This may be a fit issue, but the narrow waistband wasn’t very comfortable both during and after pregnancy. The pants stayed up well, even with the belly (you can use optional suspenders), however I think a thicker waistband (even a panel like other maternity pants) would be more comfortable on the waistline. Until I loose my extra post-pregnancy ‘juiciness’ they are cutting in a bit.
  • There are no hip pockets. This is a personal preference but I often hold my hands in my pockets while I’m hiking (perhaps not the greatest habit!).

To conclude, I think it’s so great that someone out there is making a maternity hiking pant (go Mountain Mama!), even though it may take a bit of tweaking to make it fit more body types. Let’s help women stay active through pregnancy!

Overall I’d give it 3.5/5 (due to the fit).

Thanks, Mountain Mama, for sending along this product to me for review.

  1. I have these trousers too and agree that they’re a bit stiff/rough for a whole day’s hiking but I find them perfect for general camping trousers. They fit me well, at 5’2″ that was a real surprise and I guess means the taller people lose out but I’m happy 🙂 And so far, at 24weeks pregnant the waistband has been comfy for me. But we’re all different shapes/sizes.

    1. I’m glad they are a good fit for you. Your height probably helps. 🙂 You’re right – we’re all different shapes/sizes. These pants are ideal for some people out there.

  2. Thanks so much for your feedback! The early version of the Trinity had a 2″ waistband, but after discovering that wide waistbands roll, fold, and pinch, we switched to the narrow one. We love your detailed feedback and will definitely continue fine tuning!

    1. Hi Teresa! I thought that the previous version had a thicker waistband…it’s tricky to find something that you can move rigorously in (like when you’re hiking) that is also compatible with a growing belly! Perhaps for me it was just uncomfortable because of where the waistband landed on me (again, I have a very short torso). Perhaps a wider and stronger (though stretchy) band combined with a draw cord would work…
