🔍 Detailed Review

First Impressions: Is This Really an Umbrella?

When I first picked it up, I was genuinely surprised by the weight. At 150g, it's lighter than a smartphone. True to Sea to Summit's reputation as an Australian brand known for backpacking and hiking gear, this product pushes weight-saving to the extreme.

Living up to the "Ultra-Sil" name, it uses an ultralight silicone-coated fabric, and folded down it's only 24cm long, so it slips easily into even a small bag.

Using It in Real Life

The lightness is a real strength: The 150g weight genuinely impresses. You barely notice it in your bag, and folded down to 24cm, it fits perfectly into a backpack's side pocket. It's light enough to toss into an EDC bag without a second thought.

The size is more than enough: With a 98cm diameter when open, it's plenty for one person. It handles rain without any issues at that size.

Dries quickly: Thanks to the silicone coating, water shakes off easily, and it dries fast even when it gets wet. That's a genuinely useful trait while traveling.

Quiet in the rain: Because the fabric is soft, it doesn't make much noise in the rain. You get much less of that "pitter-patter" sound you hear with a regular umbrella.

The Downside: Durability Issues

It's fragile in wind: Honestly, this is the biggest issue. Because the frame is thin to keep the weight down, it's weak against wind. In strong gusts, it can flip inside out easily, so you have to handle it carefully. Over 2 years of use, I've always been cautious on windy days.

It needs delicate handling: Because the fabric is thin, rough handling can tear it. You need to fold it carefully when putting it into the case, and you shouldn't store it near anything sharp.

Frame strength: It doesn't feel as sturdy as a regular umbrella. I always find myself thinking, "this could break at some point."

After 2 Years of Use

For travel or light hikes, it's still my top choice. Nothing else compares in terms of weight and size. That said, on days when strong wind is expected, or in rough conditions, I end up bringing a regular umbrella instead.

I've used it carefully for 2 years and it's held up without major damage so far, but I do think of it as a consumable that I'll eventually need to replace. I've also found myself wishing I had a sturdy backup umbrella on hand as well.

🎯 Final Verdict

The Sea to Summit Ultra-Sil Umbrella is excellent when used for the right purpose.

For situations where weight really matters — backpacking, travel, light hikes — it's genuinely great. The 150g weight and 24cm folded size are advantages no other umbrella can match. It's no burden to carry in a bag, and it's really convenient to pull out whenever you need it.

That said, durability falls short if you're looking for a main umbrella. Keep in mind that it's fragile in wind and requires delicate handling. Over 2 years of use, I've always handled it with care, and I've reached for a different umbrella on windy days.

It's a genuinely great secondary umbrella for travel or hiking, but I wouldn't recommend it as your everyday main umbrella. The best combination seems to be owning a sturdy regular umbrella alongside a Sea to Summit.

If you specifically need a light, compact umbrella and are confident you can handle it carefully, it's well worth the investment.
