A half-eaten Phoenix Bar gripped in a fist outdoors

Every bite packs more calories.

Up to 557 calories, 66g carbs and 19g protein

All in one compact bar of only 120g, with carbs, fats and plant protein together. That's about 4.6 calories per gram, more than typical energy bars, protein bars or gels, so you get more from less food, whether you're fuelling a long day or trying to gain weight.

Easy to get down

Low volume, soft and not too sweet, so it's a smaller ask when you don't feel like eating, and you can make it into porridge.

Soft, melts in your mouth

It's a pressed oat flapjack, so it's easy to bite and chew, and it stays soft at minus 45. It won't melt in desert heat either.

Not sickly sweet

Sweet gels and bars get hard to face after a few hours, so all six flavours are deliberately mild.

Storage and shelf life

Up to a 2-year best-before date. Store somewhere cool and dry. The bar holds its texture in freezing and hot conditions, so it's fine in a pack, drop bag or kit box.

Eat it whole, break it into chunks for long days, or crumble it into water or milk for a quick porridge. It doesn't need to be hot.

Flaming Phoenix Bars featured as a star in my food supply for my recent South Pole expedition! Easy to eat, even at -45c.

Phoenix Bars are helping me to weight gain prior to Everest next year, which is a big problem for me.

They don’t freeze easily, provide the sustained energy I need, and help prevent weight loss during intense climbs.
