Review: Montbell U.L. Trekking Umbrella

A reflective umbrella will keep you significantly cooler than a non-reflective model when hiking in hot conditions. That’s the long-time consensus in the backpacking community. There’s only one problem………’s largely a myth.


Crossing Death Valley with the Montbell UL Trekking Umbrella | Lowest to Highest Route, CA, USA, 2014.

I bought my Montbell U.L. Trekking Umbrella in 2011.

Initial impressions? Two things came immediately to mind:

1. WeightTipping the scales at 5.8 oz (165 grams), it was the lightest umbrella I had seen.

2.  DurabilityThe folding hinges & gossamer-like materials, made me wonder whether or not it would hold up long term.

In regards to #2, I’m happy to report that four years and many miles later, it is still in very good condition and showing little in the way of wear and tear. As for the other details, they go something like this:

Testing Grounds

  • Include: Queensland, Australia (summer), Pacific Northwest (autumn), southern California (spring), Colombian Andes (summer) and Mexico’s Sierra Madre (all seasons).
  • Note: I don’t carry an umbrella on all of my backpacking trips. In certain environments, I think they’re more trouble than they’re worth. Click here for a brief overview of the conditions for which I think umbrellas are well suited.

Specs & Features

  • Weight – 5.8 oz (165 grams)
  • Folded Length – 9 inches (24 cm)
  • Open Width – 2 ft 8 inches (86 cm)
  • Canopy Material – 15-denier Ballistic Airlight nylon

    Telescopic: The folding hinges of the Montbell U.L. are what make it so compact. As I alluded to in the introduction, at first glance I had my doubts in regards to the durability of this particular feature. However, in practice they’ve held up fine; they are definitely tougher than they look.

  • Aren’t telescopic umbrellas finicky to deploy and store? I’ve read this complaint on various reviews. Yes, you do need to manually unsnap the ribs each time you repack it, however, this takes all of about 10 seconds (less to deploy it). No biggie. In four years of usage, I’ve never found it to be an issue and have yet to have one of the struts/ribs break on me.

How does it Compare with its Competitors?

PROS – Size & Compactness

At 5.8 oz, the U.L. Trekking umbrella is some 2.2 oz lighter than the much-loved, but now defunct Golite Chrome Dome, (Note: The Chrome Dome, Gossamer Gear Liteflex HikingSix Moons Designs Silver Shadow and the Euroschirm Swing Liteflex are all one and the same umbrella. They just have different logos on them. All four models are made by Euroschirm).

In regards to compactness, with a folded length of just 9 inches, it is some 16 inches shorter than its above mentioned competitors. This is significant from a storage perspective. Over the years, the one issue I have had with the otherwise excellent Golite model, is that when not deployed the umbrella tends to stick out over the top of a relatively small/lightweight backpack (see photo below). If you’re hiking on a well maintained pathway, this is not much of a problem. However, when hiking off-trail and/or on overgrown pathways, it has a tendency to catch on branches, bushes and felled trees.

CONS – Deployment & Coverage

As mentioned above, the Montbell U.L. takes longer to deploy than the Chrome Dome/Euroschirm umbrellas. In addition, due to its smaller canopy, the UL Trekking umbrella can’t match its larger-sized competitors when it comes to keeping the rain off you. Not so much the head or the upper torso, but from the hips down. Similarly, due to it’s smaller coverage it also lags behind in regards to keeping your pack dry. However, this last point is no biggie if you’ve lined the inside of your backpack with a trash compactor bag.

No Reflective Coating?

A reflective umbrella will keep you significantly cooler than a non-reflective model when hiking in hot conditions. That’s the long-time consensus in the backpacking community. There’s only one problem ………’s largely a myth.

Based on my experiences in the field (I used a GoLite Chrome Dome in 2006/2007, and then dusted it off for the Bibbulmun Track & Larapinta Trails in 2010) I’ve long believed that the discrepancy in temperature between hiking under a reflective canopy, as opposed to a non-reflective canopy, is negligible. One or two degrees max.

By way of explanation, I turned to Greg “Malto” Gressel – uber-hiker, gearhead extraordinaire, engineer and all-around sciencey-type:

“The reason there is only a miniscule difference between coated and uncoated umbrellas, is because any air movement will nullify the discrepancy in surface temperature due to convection. As a hiker is walking along at 3 mph, the air will be replaced with air at ambient temperature.”

In 2013, Dirtmonger completed an incredible 3000 mile plus loop around America’s southwest – much of it in the sweltering summer months | He made the switch from the Chrome Dome to the Montbell UL Trekking Umbrella in early 2015.

Recommended Usage

The Montbell UL Trekking Umbrella is not ideal for all conditions. I would not recommend it over its larger sized competitors for high precipitation areas such as the Scottish Highlands, Pacific Northwest or even the Appalachian Trail. However, for long distance hikes such as the Pacific Crest & Continental Divide Trails, upon which an umbrella’s primary purpose is to provide shade / sun protection, I think it’s a better option than the heavier and significantly less compact Golite Chrome Dome (or equivalents).

Review: Montbell U.L. Trekking Umbrella — 15 Comments

  1. Great review……living in the UK we don’t have such a problem with too much sunshine, but we do get some rain!!!!
    I have used a collapsible umbrella on hikes but, although compact, mine isn’t the lightest and there’s the issue of trekking poles as well…..the main problem I find is, usually with rain there’s wind!!!

  2. Another great article Cam! I use the Euroshirm 8oz. Chrome Dome umbrella with a hands free rig made from items I already had. Nice dry place to eat chow or take a break and I will hang it from a tree limb and change clothes underneath. Windscreen for cooking, heck how about hanging clothing inside the canopy to dry! I could keep going! Thanks again Cam!

  3. Diggin this site! I am a bit of an adventurer, looking to do some long trails outside the US and found your site. But recently came back to it doing research for what umbrella to get for upcoming PCT thru. If the UV really isn’t necessary, what do you think about the normal, non-coated Liteflex as a compromise? Bigger area covered, but lighter weight (7.3 vs 8.3), but still able to go without a rain jacket unless it gets really bad? And can double as ice-ax a la Francis Tapon? Haha

    Anyway thanks for your site, will be scouring this for sure for post-PCT adventures.

    • Due to the wind factor, I’d be hesitant to go without a lightweight rain jacket to complement the umbrella. The PCT has some pretty exposed sections. All the best on your hike!



  4. Great review!
    The goal is to hike the JMT with a single umbrella.
    I’m struggling with deciding between:
    1. Liteflex Trek Umbrella with a more robust and larger design with UV block
    2. Montbell sun block umbrella. 6.3oz weight and more compact with UV block
    3. Montbell travel umbrella. An insane 3 oz weight but less robust and no UV

    If the silver coating is a myth then score one point for #3. #3 has insane weight savings and is the most compact.

    So, for me the final question is wind. In the event of a unexpected strong gust–will the umbrella get shredded or will it merely turn inside out without breaking, only requiring me to pop it back the other way and perhaps stow it until the wind dies down, using only my light weight rain gear or hat/clothing if it’s a sunny and windy day.

    Recommendations? How has your Trekking umbrella held up to being blow inside out and returned to it’s right orientation?


    • I’ve never had one of my umbrellas shredded, however, if it’s really windy I’ll just leave it stowed in the pack. In regards to recommendations for the JMT, I’d probably give the Travel model a miss (not convinced about its durability), and go with one of the Trekking umbrellas or the Sun Block.

      • thanks! I think I’ll go with the sunblock after reading more. amazingly, of all the blogs about the sunblock, I’ve never read of or had someone reply in the comments that they’ve had their sunblock invert due to high wind. I keep trying to find someone who’s had it invert and then successfully pop back to it’s original shape. It’s some kind of marvel of engineering or people are very wise about putting it away during high wind so that it never risks inverting (blowing inside out). I keep trying to find out how well they hold up after inverting. thanks again for the feedback!

  5. One point I’d like to add is that temperature is one thing, but UV protection is another. I think it was Harvard that did a study on UV penetration of different-colored unbrellas, and found that only about 80% of the UV rays were intercepted by a medium-density colored umbrella (ie, red, brown, etc). Give me a reflective type such as the Montbell Sun Block Umbrella at 99.7%!

    • I’ve seen them, but I haven’t used one as yet. I suspect they are ok in light rain/no wind/sheltered forest-type trails. I think I’d prefer to take the 2oz-3oz weight penalty and go with something a little bit sturdier.

  6. I am looking for a hands free Option something that can mount to my backpack I am attempting the Pacific crest Trail this March that would like it for the desert phase for sun protection. Any good ideas

  7. I believe there is a situation where sun shading works wonders. Living in the UK you get used to chilly weather, even in summer, and your body acclimatises through the year. But the weather is very changeable, and when we get a sudden heatwave lasting a week or two in July/August, the sun beating down is difficult to bear when you aren’t used to it. The air temperature might be warm, but I usually reckon the sun adds 10-15C. A black umbrella helps a lot, but radiates some heat onto you like a lens. I have yet to try a reflective umbrella, and I can imagine it would be much better.

  8. I disagree on the no temp diff; that is my GoLite chrome dome is especially helpful when standing still. It offers a great reduction in perceived temperature (I haven’t measured); but on trips or at local summer sports events, people always want my umbrella. Even if for the standing still benefit, i’d only pick a reflective one
