Here is a great chance to get an entire camping sleep system where each piece is designed to work with the others. And if you’re set on a sleeping bag, say, you can add to its warmth and performance with a Sea to Summit sleeping pad or a liner.
Sea to Summit’s latest mummy bags use the brand’s Free-Flow zipper system, which are secondary openings in the upper portion and the footbox. These let you stick your arms out and still keep your core warm while the footbox opening lets you pull up the bottom of the bag or liner and move around camp.
The companion liners are shaped to play simpatico with the openings in the bags for a more compatible sleep system. And you can buy with confidence knowing that Sea to Summit offers a lifetime warranty on most of its bags and liners.
This anniversary sale runs through May 20 and covers all of the components of Sea to Summit sleep systems: Down and Synthetic Sleeping Bags, Sleeping Pads, Liners, and Camp Pillows.

Sea to Summit Sleep System
Sea to Summit makes a wide range of outdoor equipment, but this sale is all about the sleep system components.
If you need a new sleeping bag, the Free Flow system offers mobility around camp and inside a tent. It also pairs with the brand’s latest sleeping bag liners.
You don’t have to buy an entire sleep system to save. However, this sale may nudge you into adding a liner to your existing sleep system or entice you to see why the Aeros pillow is so popular.
The best part about this sale is that the savings increase with every piece of the sleep system you buy (up to four). That means you can buy a warming and cooling liner and a pillow and enjoy 20% off everything!
Ascent Down Sleeping Bag & Women’s Ascent
Sea to Summit packs warmth into the Ascent Down bags with 750+ Ultra-Dry Goose Down (RDS-certified). To fight drafts and trap more heat, the bag has a cinch-down and a draft tube protecting its side zippers.
If things get too warm, the Free-Flow Zip lets you vent areas around your core or completely unzip the bag to use like a quilt. That range in temperature makes it a solid three-season option, and the handy Free-Flow configuration means you can keep it around on as you sit up in your tent or put it around camp.
The Ascent uses box baffles throughout but places them vertically in the torso to help prevent the down fill from shifting. Other design notes are the anatomical footbox and the 20D recycled nylon shell and liner. The women’s-specific fit is narrower in the shoulders and wider between the hips and knees.

The Ether Light XT Insulated Mat measures a beefy 4 inches thick and offers two types of insulation for 3.5 R-Value warmth in three seasons. It brings the brand’s Air Sprung Cell design into the market of thicker sleeping pads. The XT Air Sprung Cells are made of loops of strong material that hold warmth, yet flex to make a comfortable sleeping surface.
A 30D/40D face fabric is durable and uses Sea to Summit’s noted lamination technology to reduce the chances of springing a leak at the seams. The pad’s top fabric is also brushed to make it quieter.
This pad uses the brand’s multifunction valve for inflation and deflations and comes with a stuff sack that doubles as a pump. There’s even an antimicrobial treatment in the TPU lamination to help prevent mold from growing inside the pad.
All of the women’s Air Sprung Cell mats use higher-density Thermolite insulation (compared to the unisex model) to prevent convective heat loss and are laminated with a tech that reflects radiant heat back into the pad.
As you’ll see below, the pad uses the brand’s Pillow Lock system to keep the Aeros Pillow from sliding around.

Available in mummy or rectangular shapes, the Breeze Liner prioritizes moisture management. The fabric is mostly Coolmax EcoMade blended with biobased Tencel Lyocell fibers to help wick moisture away from your body. The rectangular model has a built-in pillow sleeve shaped to fit the Aero Pillow.
Sea to Summit also makes insulating liners for those planning camp missions in colder temps.

The Aeros is an inflatable backpacking pillow with a scalloped shape that offers support to side sleepers and back sleepers alike.
It fills with a few breaths and can be adjusted with Sea to Summit’s unique multifunction valve. The interior bladder is made from contoured TPU for durability and is surrounded by a synthetic fill between the surface that reinforces airflow to buffer the cold.
The top has a brushed 50D polyester knit for a soft surface that offers grip and is quiet when turning during nocturnal hours. Plus, the Aeros has a Pillow Lock system to secure the pillow to one of the brand’s sleeping mats.
