Warm nights.
Light pack.

A summer bag built for 40 to 70°F, when a three-season bag is simply too much. 2.7 lb, water-resistant 210T polyester, and a compression sack so it disappears into a pack rather than filling it.

Description

Most sleeping bags sold as “three-season” are too warm for an actual summer night. You end up half out of the bag, or sleeping on top of it. This one is built for the range you are really in from late spring to early autumn — 40 to 70°F — and it weighs and packs accordingly.

At 86.6 by 31.5 inches it fits campers up to 5'11", with an envelope cut and a roomy foot box rather than the zipped-in feel of a mummy bag. 2.7 lb on its own, 2.9 lb with the compression sack it comes with.

Built for the nights it is actually warm

Three reasons a three-season bag is the wrong tool in July. Three fixes.

Rated 40 to 70 degrees for summer camping
01 — Made for warm nights

40 to 70°F, not 30

A bag rated to 30°F is dead weight in summer — you carry the extra insulation all day and then sleep on top of it. This is built for the range you are actually in, so the fill is thinner, the fabric breathes, and you stay in the bag instead of fighting it.

Water-resistant 210T polyester shell
02 — Dew, spray and spills

210T water-resistant shell

Summer camping means condensation on the tent wall and wet grass under the groundsheet. The shell sheds that rather than soaking it up, it dries quickly when it does get wet, and the whole bag goes in the washing machine afterwards.

Packs down into the included compression sack
03 — Light enough to bother

2.7 lb, into its own sack

The bag you take is the one you can carry. At 2.7 lb it is roughly half a typical three-season bag, and the included compression sack pulls it down small enough that it rides inside a daypack rather than strapped to the outside.

The numbers

Warm enough. Light enough. Small enough.

The numbers that decide whether it is the right bag for the season.

We have an upcoming trip scheduled and I wanted to use a sleeping bag in the RV rental. The bag seem great, is super light and has a ton of room for me to toss around in. Not being a regular camper, I didn't think the more restrictive feet of a "mummy" type bag would be for me. Plus, my "Velcro type" dog will have room to lay on part of it. Can't wait to use it!

Best lightweight sleeping bag, great price!

Great lightweight sleeping bag! It is long with a generous width. The best part, because I’m always cold, is the generous hood with a drawstring that adjusts both the hood and the sleeping bag top so you can snuggle in and keep the warmth inside. Love it!

Very warm

Very warm. Enough room for my daughter to crawl in with me.

Exceeded expectations

Spacious, light weight sleeping bag. I was surprised it kept me warm tenting in 47 degree weather.

Great sleeping bag but be sure to choose the right size!

Very pleased with the quality of this sleeping bag overall, however, I made the mistake of ordering the Single Size which is uncomfortably tight around my feet when zipped up. Other than that I am pleased with the sleeping bag so I simply bought another one and now use one as ground cover and one as a blanket without being closed in a "bag" so to speak. Very comfortable, breathable, and easy to clean. For men, definitely go for the XXL or Double Size.

Questions

Good to know before you camp

What size is it, and will I fit?
86.6 inches long by 31.5 wide, sized for campers up to 5'11". If you are taller than that, the XXL version runs 90 inches long and is the better choice.
How cold can I use it in?
It is rated 40°F to 70°F — built for late spring through to early autumn rather than the full three seasons. Reviewers report staying warm tenting at 47°F. If your trips run colder than that at either end of the year, the 3-Season Sleeping Bag is rated 30–70°F and is the better choice; for deep winter you want a dedicated cold-weather bag.
Is it too warm for summer?
No — the polyester breathes, and you can unzip it fully and use it as a quilt. Several customers use one as ground cover and a second as a blanket.
How heavy is it to carry?
2.7 lb on its own, 2.9 lb with the compression sack. That is roughly half what a three-season bag of the same size weighs, which is the whole point of a summer-specific bag.
Can two people fit?
It is a single bag at 31.5 inches wide, though there is room for a child to climb in with an adult — a few reviewers mention exactly that. For two adults, either zip two together or look at the Double Sleeping Bag.

Sleep like you meant to.
