Haglöfs Unisex L.I.M +1 sleeping bag: first impressions

Haglöfs’ L.I.M collection stands for Less Is More – and it’s a pretty suitable name for their L.I.M +1 sleeping bag, which weighs just 473 grams (just over 1lb) but packs in plenty of warm goose down (Responsible Down Standard certified).

The slick shiny look and feel of the outer material of the L.I.M might not suit campers who like a more cotton-y touch to their sleeping kit. The L.I.M’s impressively light weight is ideal for backpackers looking to keep their pack size and weight as small as possible for mountain races or multi-day hikes in spring and summer.

This bag was clearly designed with fast and light adventurers, mountain marathon runners and wild camping in mind. To keep weight down, it does away with a zip – instead there’s a drawstring at both the top and the bottom of the bag, which means you can open it up to ventilate the bag and regulate your temperature easily.

Haglöfs Unisex L.I.M +1 sleeping bag: in the field

Swapping a zip for a double drawstring system, with openings at the top and the bottom, not only saves weight, it also adds to the versatility of the bag. On test we found it to be a great asset for making sure you stay the right temperature in chilly weather, but that your sleeping bag is still suitable for hotter nights. For more on all of this, check out Sleeping bag temperature ranges explained.

The foot panel of the bag is also more tightly quilted than the rest of the bag, to trap in heat – if you find your feet regularly either freeze or overheat when camping, you might well love the versatility of this design.

The open bottom also allows you to wear the bag when you’re getting ready for bed or around the campsite, without having to hop about.

While this is a fairly versatile sleeping bag, be aware that the comfort temperature ratings (6°C/43°F) mean that it’s best used in the summer months (stretching to late spring and early autumn when the weather behaves itself) at close to sea level. Used in the correct conditions, it’s an excellent lightweight bag and one of the best 2-season sleeping bags we've have the pleasure of sleeping in.
