メンズ O3 ジャケット

A great piece of kit with typical Buffalo quality workmanship. Lightweight, packable providing a broad range of comfort across all types of weather. Later up for more warmth or layer down for higher energy output activities.

Also looks great down the pub!

Love it!

This is a great jacket that manages to be cool when walking and warm when you stop - scrunches up very small for the warmth it gives. I love my other heavier jackets but this one is going to be great for spring/autumn use

Love it. Since buying a week ago I’ve worn it running and cycling. Great to just take the chill off. Colour is amazing.

Really nice jacket, bought to replace a more casual Patagonia Baggies jacket for walks in drizzle/unpredictable British weather. I've already worn it 15 minutes of rain and didn't feel wet at all either, stayed comfy and dry. Compared to the Patagonia jacket it's replacing, it feels significantly lighter and less clammy/stuffy, owing I assume to the more breathable material. It also didn't wet out and get heavy. I think in general it'll much more adaptable to the inconsistency of British weather.

I went slightly bigger on size than recommended (42) so I could also layer under/get fatter, I'd say the size chart for this is pretty spot on.

I've knocked it one star because I kinda wish it had internal chest pockets, though it'd probably detract from next to skin comfort. The jacket also had multiple excess threads in several areas I had to cut out of the bag, which at this price point just felt less than ideal.

Exactly what you'd expect from a Buffalo jacket - beautifully made, great materials and very comfortable. The torchlight orange is a fantastic colour too.

Glad I decided to add this to my collection!

Super shirt for when it is just a tad chilly, windy or drizzling

Fantasticly helpful team at Buffalo and a brilliant yet simple product, with a little tweak to make it my own.

As brilliant as always.

I bought this jacket for my partner who has been wearing Buffalo for over 20 years - used in the mountains and walking all over the UK. He is delighted with the new 03 jacket as an alternative to his Special 6 and Belay Jacket in warmer weather. These products are not cheap but they offer decades of service …. Customer service was great - ordered online and delivered the next day.

Brilliant jacket

Very impressed with quality, sizing. Great new colour with bright orange. I already have a belay jacket so this is a great addition for the warmer months. You can’t fault Buffalo quality. I’ve still got my original Buffalo Special 6 which I got in Royal Marines 35 years ago!

Outstanding jacket and likewise service, I wouldn’t expect anything other than utter professionalism and the best products money can buy.

Outstanding!

As always superbly made and the quality is amazing.
Buffalow has been in my life since its origin.
The brand for wild experiences.

Bought as 60th gift for a hill walker

A fantastic piece of kit, surprisingly warm yet very lightweight too. Clearly built to withstand the elements!

Great jacket, warm and very tough 👍

Great quality and fit, ideal for chilly summer evenings

Champion

Tested in the Scottish Highlands today. Performed admirably. Perhaps the best thing is how quickly it dries out. The only slight change for me would be a longer strip of velcro for the cuffs.

Fantastic jacket. Customer service with this company is flawless. I've been a customer of the company for 17 years. The best quality you can ask for.

So far, so excellent.
I've worn this a few times now in June 2026.
Lovely bright colour, super lightweight, nice texture against the skin.
The jacket was a commission item and arrived within approximately 2 weeks, which was half the time advertised and what I imagined it would take.
I have exclusively worn it next to the skin and hiked my local area which is the Carneddau, the wind resistance is fantastic and I have been warm enough with just the O3 on even when windchill was down at around 3 degrees Celsius.
Unfortunately, the weather has turned far too warm now to wear it, so, maybe it's next outing will be in a few months or maybe days, this is Wales of course!

Great jacket.
Made up.

Been wearing Buffalo since early 90s. That shirt is still in use. Their kit is the best and this is a great addition in gorgeous colour. Worn it virtually every day since I got it.

Fantastic Jacket, Buffalo jackets are the best

Fantastic Jacket in the Buffalo style, just lighter for warmer times. Very wearable. Great quality and style.

A brilliant versatile all year round jacket & an excellent lighter alternative to my mountain shirt.

Brilliant bit of kit.
Nice & lightweight but still enough insulation for the cooler weather

Lovely jacket. Great quality. Just right for the warmer months. Fits true to size

I love this jacket. I've worn it over two consecutive June weekends in Wales. Typical weather, driving rain or howling gale and drizzle on the top of hills, baking sun in the valleys. The 03 jacket works across it all. Just adjust the zips and vent accordingly. However, some pit zips would make it 5 stars. It's well-made, fuss-free, and the orange is highly visible.

Excellent quality bit of warm kit for the summer months.

This jacket meets the normal Buffalo standard of excellence. Don’t let the price put you off my last jacket is 20 years old and still going strong. This one is so light and feels so soft inside is already my go to for the daily dog walk. I had a hour in the rain and stayed dry. The wind was gusting 30mph and didn’t drop the inside microclimate. Ive wanted a thermalite jacket for decades but could never find one in stock, this I think is very similar. The thermalite trousers have been bomb proof and I think O3 jacket will be too.
