• Left or Right Zip

Hip Length Zipper (Standard)

Full Length Zipper (Custom +1oz) Note for Full Length Zip in Comments When Ordering.


1.6oz sq/yd Cuben Fiber 2-Layer eVENT Fabric TOP. This version is 2oz lighter. +$75, custom, non returnable. This option not available as all eVENT top and bottom.

Our standard and long proven 3-layer style eVENT is 2.8oz sq/yd. This lighter weight option is a 2-layer Cuben Fiber reinforced eVENT fabric. What's the functional difference? The Cuben version is lighter- it has no inner protective layer and so will have slightly shorter service life. The standard 3-Layer eVENT has an inner tricot scrim layer that protects the eVENT membrane and will last longer if used very frequently. The functional breathability and waterproofness is about the same. A LG Soul Bivy with the 2-Layer Cuben eVENT TOP is about 2.5 oz lighter weight vs the 3-Layer eVENT top.

User Tips & Reviews

FKT eVENT Soul Bivy VS regular eVENT Soul Bivy
The FKT version has all the same features and measurements. The FKT version uses a lighter cuben fiber bottom (1oz/sq/yd vs 1.4oz sq/yd cuben) and a lighter eVENT upper ( 1.6oz sq/yd 2layer vs 2.8oz sq/yd 3 layer eVENT) . The durability of the regular eVENT Soul Bivy a bit better than the lighter FKT bivy. Breathability and functionality is about the same. FKT version costs more due to the much higher priced lighter cuben reinforced eVENT upper fabric.

BPL review by Ryan Jordan
*Overall Rating: Highly Recommended*
"There's a lot to like about the Mountain Laurel Designs Soul Bivy: light weight, exceptional material quality (and the performance of those materials), solid construction quality, and a fundamentally sound feature set that makes it versatile enough to use as a standalone shelter while still being light enough to pair with a tarp for more versatility. Climbers, bikepackers, and packrafters will be particularly interested in the Soul Bivy because of its light weight, utility, and small packed size. "

Stand Alone Bivy Sack User Tips:
1: Campsite location can make a huge difference. In bad weather, finding a semi protected area under a rock overhang, behind a natural windbreak, the base of a large conifer tree or cave can offers a lot more livability.
2: Using a synthetic sleep quilt offers measure of comport, warmth and safety vs a down bag in the event you have to enter and exit in rain conditions or are forced to sleep in wet clothes.
3: Use of a pack liner keeps your gear dry in the pack and the wet outer pack body + other wet great can be stuffed into the liner for storage inside the bivy as a pillow if needed.
4: No bivy sack , even non-waterproof highly breathable DWR bivys, are 100% condensation free in all conditions. This bivy is one of the bet but taking common preventative measures to limit condensation is the key. Campsite selection, venting and containing wet gear and clothing inside the bivy are keys to lower condensation. In challenging conditions the overall goal is to be warm and slightly damp and warm is far better than wet and cold or dry and cold.
5: If you expect lots of rain or very bad weather conditions consider using a small tarp + the FKT bivy for those sleep periods.
