Updated Spark series - New bags, New Fabrics and Updated construction

Sea to Summit's SPARK series of sleeping bags are their lightest bags with a warmth to weight ratio that's among the best available. For 2019 they have introduced an SP0 bag aimed at summer mountain races or fast hikes - it has a Comfort Limit of 9C and weighs in at around 250grams.

The rest of the SPARK bags (Sparks 1 to 1V) have been improved with a lighter weight inner fabric and box wall construction in the SP11, SP111 and SP1V. The previous SPARK range didn't cover lower temperatures but now for example the SP111 bag has a Comfort Limit rating of -8C but only weighs 675grams - now you can have a substantially warm bag at an even lower weight with very few compromises.

NEW Women's Version of Spark - called the FLAME

Sea to Summit have introduced a Women's version of the Spark bags, which are their lightest bags with one of the highest warmth to weight ratios available. The FLAME bags have more down in them than the Sparks providing extra warmth in the areas needed.

The FLAME bags are also wider at the hips, the tapering of the bag starts at the hips rather than the shoulders, more closely matching the female shape.

These two improvements mean less compromises for Women who want the lightest bag for mountain marathons or ultralight backpacking.

Updated EMBER quilts - Lighter fabrics and wider shoulders

Sea to Summit EMBER quilts are for those people who don't like the restraint of sleeping bags, you can tie them round your sleeping mat if you want to but the best way to use them is blanket style. The three models cover a range of conditions, and the flexible system allows two EMBERS to be press-studded together to make a double.

It's rare to find such quality built into a quilt but Sea to Summit don't compromise, 850+ Fill Power down combined with 10D and 7D fabrics and box wall construction in the EMBER11 and EMBER111 point to a very high quality product.

Quilts can't be tested to get a temperature rating so the best way of estimating their performance is to compare the amount of down in the quilt with a sleeping bag with the same amount - remembering all the down is on top with a quilt.

Thermarest Logo

NEW Thermarest Fast and Light Bags - OHM and HYPERION

The new HYPERION bags offer incredible performance at amazingly low weights, they achieve this by using the highest quality down possible, box wall construction and super-lightweight materials. The Hyperion 32F/0C packs in 245 grams of down yet only weighs 462grams in total, that means the sleeping bag shell only weighs 220grams - amazing.

If you want light weight but with a bit more space then the OHM 32F/0C is worth considering, it still has three key quality components - 900 Fill Power down, box wall construction and super-lightweight materials. There's no hood because this bag can also convert into a quilt with a zipper that extends across the foot, ideal if you like 'roomy' but don't want the disadvantage of a quilt when it gets a bit chilly.

NEW Thermarest Fast and Light Quilts - VESPER 20F/-6C, VESPER 32F/0C

The new VESPER quilts are Thermarest's most technical quilts to date, with awesome quality down (900 Fill Power), boxed wall construction and Thermarest's own ThermaCapture lining to reduce radiant heat loss. They can be fitted round a sleeping mat and Thermarest have incorporated draft protection features to help reduce heat lost due to wafting of the quilt.

Quilts can't be tested to get a temperature rating so the best way of estimating their performance is to compare the amount of down in the quilt with a sleeping bag with the same amount - remembering all the down is on top with a quilt. Thermarest have made their own estimation of temperature performance as quoted in the titles of the quilts.

Redesigned NEUTRINO PRO bags replace Neutrino Endurance

RAB's Neutrino and Neutrino Endurance sleeping bags have a huge reputation but Spring 2019 sees the culmination of three years hard work to get the absolute best performance out of the materials used. The baffles now have a chevron shape which acts to funnel the down to its correct position as you shake the bag out prior to climbing in. This has also allowed RAB to put one less baffle line into the construction of the bags - saving 10grams of weight.

There has also been an obsessive focus on the down chambers themselves, ensuring the chamber size is matched to the down volume to achieve the most efficient loft and therefore insulating value.

In line with new branding from Pertex the new names for the sleeping bags are NEUTRINO PRO, using Pertex Quantum Pro fabric (previously Endurance) offering a highly water resistant outer.

New Mens KAYU and Womens AYA - Comfort orientated Ultralight bags

Nemo are known for their innovative sleeping bags and mats designed to be comfortable on the trail, but that doesn't mean they don't 'get' the ultralight movement, these new sleeping bags have had rigorous design focus to reduce the weight while still retaining those key comfort features that Nemo are known for.

Baffle patterns are designed for optimal thermal efficiency, Thermo Gills provide effective temperature regulation and waterproof/breathable footbox and hood are provides protection from tent condensation.

These bags are designed for people who want comfort and are prepared to carry a slightly heavier bag to achieve that, while still not carrying unnecessary weight.

Nemo BANSHEE - a quilt that converts to a sleeping bag and Vice Versa

The 850 Fil Power BANSHEE ultralight down quilt is a transforming bag designed to give ultimate flexibility on the trail. Zipped up as a hoodless sleeping bag Nemo estimate its comfort limit rating to be -6C, unzipped its a sizeable quilt. Weighing in at around 770grams it could be the key part in a very flexible sleeping system.

One NEW Down minimalist sleeping bag, the PLUTON UL and one New Synthetic minimalist bag, the V NOTCH UL

The PLUTON UL weighs around 450grams and is estimated to have a comfort rating of 4C, despite being so light it has a full length zipper and 227grams of hydrophobic down, meaning the shell only weighs around 225 grams - so this is an extremely technical bag with a high warmth to weight ratio.

The V NOTCH UL aims at the same performance parameters as the PLUTON UL but with a synthetic filling - specifically Primaloft Hi-Loft Ultra Silver with a stitch free construction for maximum thermal efficiency. Weighing in at the 600gram mark it hits a performance sweet spot for a synthetic bag.
