Our sleeping bag comparison guide: find the right sleeping bag for your next adventure

Picking a new sleeping bag shouldn't feel like guesswork. With so many shapes, fills and temperature ratings out there, it's easy to end up with a sleeping bag that's too hot, too heavy, or simply wrong for the trip you've got planned. That's why we put together our free sleeping bag comparison guide — a downloadable PDF that lays out our full range of sleeping bags side by side, so you can compare specs and shop with confidence.

Why we created a sleeping bag comparison guide

We know that not every sleeping bag suits every adventure. A summer overnighter needs something very different to a winter alpine trek, and the specs that matter — weight, pack size, fill power, temperature rating — aren't always easy to compare across a whole range. Our guide pulls it all into one place. If you want a deeper dive before you download it, our article on what to look for in a sleeping bag before you buy is a great place to start.

Sleeping bag down vs synthetic fill explained

One of the biggest decisions you'll make is fill type. A sleeping bag down option, like the Sea to Summit Spark down sleeping bag, offers an unbeatable warmth-to-weight ratio and packs down small, making it a favourite for hikers who count every gram. If you'd rather have something that performs better when damp and is easier on the budget, the Sea to Summit Hamelin synthetic sleeping bag is a brilliant all-rounder. We've written more about what makes the Spark special in our piece on the Sea to Summit Spark down sleeping bag.

How to choose between our top sleeping bags

Still torn between models? You're not alone — it's one of the questions we get asked most. Our hikers swear by the Ascent range for three-season versatility, and we've explained why in why hikers swear by the Sea to Summit Ascent sleeping bag. If you're deciding between two of our most popular sleeping bags, our comparison of the Spark vs Spark Pro breaks down exactly where the extra investment goes.

Don't forget your sleeping bag bag and mat

A great sleeping bag deserves a proper sleeping bag bag to protect it on the trail, and it's worth pairing it with the right sleeping mat too. Warmth underneath you matters just as much as warmth around you, and we've covered exactly why in sleeping bag vs sleeping mat. Getting this combination right is one of the easiest ways to sleep warmer for less weight in your pack.
