For a calorie-aware festival snack, compare the calories in the whole bag you plan to eat: Seabrook lists 126 kcal for its 25g Canadian Ham bag, while Walkers lists 130 kcal for its 25g Ready Salted pack. These smaller portions do not make conventional potato crisps a low-energy food; the UK condition for a ‘low energy’ claim on solid foods is no more than 40 kcal per 100g, according to legislation.gov.uk. Keep unopened packs dry and protected from pests, and check the exact flavour’s allergen information.
If you expect to eat a whole bag at once, its per-pack calorie figure is the practical starting point. Compare the pack weight and kcal per 100g as well: a smaller bag can contain fewer calories without the crisps themselves being lower in energy per 100g.
Unopened dry snacks are worth considering when chilled food cannot be stored adequately. The Food Standards Agency advises protecting camping food from pests; keep packs dry and follow their storage instructions.
Read the ingredients and precautionary allergen wording on the exact flavour and pack you intend to take. A vegetarian, vegan or gluten-free description does not replace an allergy check.
Choose the portion you are likely to finish, then compare its label with alternatives on the same basis. Pack condition, storage and allergens also matter when food is travelling to a campsite.
| Priority | What to check | Your needs |
|---|---|---|
| Whole-pack calories | Read kcal for the complete bag if you will finish it. Check the bag weight and kcal per 100g before comparing different sizes; a smaller portion does not establish a low-energy product. | I want to know the calories in the amount I will actually eat, rather than judge a bag by its size or flavour name. |
| Portion format | Check whether a multipack contains individually sealed bags and what each bag weighs. For a sharing bag, check the labelled serving size and plan how it will be divided. | Separate bags would let me pack a defined portion for each snacking occasion. If we take a sharing bag, we will need to portion it ourselves. |
| Campsite storage | Follow the pack’s storage instructions and check its condition and date label. Keep food dry and protected from pests; the Food Standards Agency recommends sealed containers to help prevent pest contamination. | When I cannot rely on chilled storage, I want unopened dry snacks that I can keep protected in a tent or vehicle. |
| Ingredients and allergens | Read the exact pack’s ingredients, highlighted allergens and precautionary statements. Do not treat a dietary-suitability label as a substitute for its allergen information. | Someone in our group may need to avoid an ingredient or consider a cross-contamination warning, even with a familiar flavour. |
Seabrook Canadian Ham contains 126 kcal per 25g bag and 505 kcal per 100g; Walkers Ready Salted contains 130 kcal per 25g pack and 518 kcal per 100g, according to the manufacturers. For a solid food, the UK ‘low energy’ claim condition is no more than 40 kcal per 100g, according to legislation.gov.uk.
Use the whole-pack figure to choose a portion. If you specifically need a food meeting the low-energy claim condition, check another snack category’s own nutrition label rather than treating a small crisp bag as equivalent.
Tyrrells lists 208 kcal for its 40g Lightly Sea Salted pack, while Walkers lists 130 kcal for a 25g Ready Salted pack. The larger pack contains more food, so those whole-pack figures do not, by themselves, describe a difference in energy per 100g.
Compare whole-pack calories for the portion you expect to eat, then compare kcal per 100g if you want to assess the products on a common weight basis.
A labelled serving does not divide the contents for you. Tyrrells describes its 150g Lightly Sea Salted bag as five 30g servings; once a sharing bag is open, the remaining crisps also need protection from damp and contamination.
For individual portions, consider intact smaller bags. For a group, divide a sharing bag before eating and keep the remainder in a clean, closed container.
Walkers says its Ready Salted crisps are made in a factory handling several allergens, and Tyrrells states that its Lightly Sea Salted crisps may contain milk. Plain-sounding names do not answer an allergy question.
Check the ingredients and precautionary wording on the exact pack you buy, particularly when packing for someone with an allergy or intolerance.
These examples describe particular products or ranges, not every flavour a brand makes. Use the current pack label for the format you are considering.
Walkers Ready Salted has a labelled 25g pack that makes a whole-bag calorie comparison straightforward.
Seabrook’s individually packed examples show why the flavour and bag size both belong in a calorie comparison.
Tyrrells Lightly Sea Salted comes in a 40g single pack as well as larger formats.
KETTLE Lightly Salted provides a per-100g figure for comparing energy on a common weight basis.
Pipers describes a flavour-led crisp range made with selected ingredients.
These individually portioned potato crisps and potato-based snacks offer different shapes, flavours and pack sizes for festival packing. French Fries, potato sticks and ring-shaped snacks should not be treated as identical to sliced potato crisps; compare each exact pack’s nutrition label before choosing by calories.

Six 18g packs offer separate portions to take out during a festival. French Fries are a potato-based snack rather than sliced potato crisps; check the exact pack’s calorie and allergen information before choosing it as an alternative.

Five 20g packs provide separate portions for travelling or camping. These are tomato-flavoured potato sticks, not conventional sliced crisps; use the exact pack’s nutrition and ingredients label for your comparison.

Six 24g bags give campers individually packed portions. These are a ring-shaped potato snack; check the calories for a complete bag and read the Cheese & Onion pack’s allergen information.

Six 24g packs provide defined portions for a camping bag. Check the calories and allergen statement on this Salt & Shake variant rather than applying figures or advice from another Walkers flavour.

Six separate 25g bags make it possible to pack one portion at a time. Walkers lists 130 kcal per 25g Ready Salted pack and 518 kcal per 100g; check this pack’s current nutrition and allergen label before packing it.
No. A smaller bag changes the calories in that portion, not the crisps’ kcal per 100g. According to legislation.gov.uk, the UK condition for a ‘low energy’ claim on a solid food is no more than 40 kcal per 100g; the manufacturer-labelled crisp examples discussed here are above that figure.
Start with calories for the complete bag. Seabrook lists 126 kcal for its 25g Canadian Ham bag, and Walkers lists 130 kcal for its 25g Ready Salted pack. Use kcal per 100g separately when comparing products on the same weight basis.
Unopened dry snacks can be considered when adequate chilled storage is not possible. The Food Standards Agency suggests taking predominantly dry foods in that situation and recommends sealed containers to help protect food from pests. Follow the crisps’ storage instructions and check the pack condition and date label.
Yes. Walkers’ Ready Salted information includes a factory-handling statement covering several allergens, while Tyrrells says its Lightly Sea Salted crisps may contain milk. Read the ingredients and precautionary wording on the exact pack you will take.
No calorie comparison follows from that flavour description. Tyrrells lists its Lightly Sea Salted crisps at 519 kcal per 100g, and KETTLE lists Lightly Salted at 516 kcal per 100g. Check the nutrition panel and pack size if calories per snack are your priority.
