With a <strong>comfort temperature of +7 \u00b0C<\/strong>, it is well suited to summer use in mild to cool conditions.<\/p>\n<p>It is an excellent choice for <strong>hiking, trekking, bikepacking, camping, hut-to-hut trips and travel<\/strong>, as well as mountain trips when temperatures are suitable. A good option when low weight and compact pack size matter, but you still want more warmth and sleeping comfort than a dedicated ultralight summer sleeping bag provides.<\/p>\n<h3>Down + wool \u2013 why DownWool\u00ae?<\/h3>\n<p><strong>DownWool\u00ae 2.0 combines 70% down with 30% wool.<\/strong> The down provides excellent insulation with low weight and pack volume, while the wool helps regulate both temperature and moisture inside the sleeping bag.<\/p>\n<p>This is particularly useful in changing conditions. As humidity increases, conventional down can lose some of its insulating performance, while the wool in DownWool\u00ae helps create a more balanced microclimate and makes the insulation less sensitive to high humidity.<\/p>\n<p>In practical terms, this means <strong>a more stable and comfortable sleeping climate throughout the night<\/strong>, particularly as temperature and humidity change.<\/p>\n<h3>For mild to cool summer nights<\/h3>\n<p>Summer Light 2.0 is tested according to EN ISO 23537-1 with a <strong>comfort temperature of +7 \u00b0C and a limit temperature of +2 \u00b0C<\/strong>. Gr\u00fcezi Bag recommends a practical operating range of <strong>+7 to +24 \u00b0C<\/strong>.<\/p>\n<p>This gives Summer Light 2.0 noticeably more temperature margin than an ultralight summer sleeping bag, while retaining low weight and a compact pack size. Its temperature-regulating DownWool\u00ae insulation and practical foot ventilation also make it comfortable across a broad range of summer conditions.<\/p>\n<p>Temperatures can fall quickly at altitude even in summer, so conditions and the weather forecast should always be taken into account when choosing a sleeping bag for mountain use. Individual sensitivity to cold also varies. If you tend to feel the cold, allow an additional temperature margin when choosing your sleeping bag.<\/p>\n<h3>Comfort without unnecessary weight<\/h3>\n<p>Summer Light 2.0 includes several of the comfort features found on Gr\u00fcezi Bag&#8217;s warmer models, including an <strong>adjustable hood, lightweight thermal collar, pre-shaped footbox and pillow pocket<\/strong>.<\/p>\n<p>The two-way Auto-Lock zip can be opened from either end and features anti-snag protection to reduce the risk of catching the outer fabric. Gr\u00fcezi Bag&#8217;s foot ventilation system also allows excess heat to escape \u2013 or your feet to rest outside the bag \u2013 without having to open the entire sleeping bag.<\/p>\n<p>Internal and external pockets provide convenient storage for small essentials you want to keep close at hand during the night.<\/p>\n<h3>More room for better sleeping comfort<\/h3>\n<p>Gr\u00fcezi Bag places considerable emphasis on ensuring that a sleeping bag does not feel unnecessarily restrictive. <strong>More space around the body makes it easier to move and turn inside the sleeping bag<\/strong>, rather than having the whole bag move with you as you change sleeping position.<\/p>\n<p>This is not only about comfort. If a sleeping bag fits too tightly, the body can compress the insulation. As the loft is reduced, its ability to retain warmth can also be reduced.<\/p>\n<p>For this reason, temperature ratings, weight and pack volume should not be considered in isolation when comparing sleeping bags. <strong>A small difference in weight can also reflect a roomier cut and more usable space around the body.<\/strong><\/p>\n<p>Summer Light 2.0 is available in three sizes with different overall lengths, shoulder widths and foot widths, allowing you to choose a size that suits both your height and the amount of room you prefer.<\/p>\n<h3>Choose the right size<\/h3>\n<p>DownWool Summer Light 2.0 is available in <strong>Regular, Long and Extra Long<\/strong>, allowing you to choose a sleeping bag according to both your height and the amount of room you want around the body.<\/p>\n<p><strong>Regular<\/strong> is recommended for body heights up to 175 cm and has an overall sleeping bag length of 200 cm, a shoulder width of 77 cm and a foot width of 50 cm.<\/p>\n<p><strong>Long<\/strong> is recommended for body heights up to 185 cm and has an overall sleeping bag length of 215 cm, a shoulder width of 80 cm and a foot width of 50 cm.<\/p>\n<p><strong>Extra Long<\/strong> is recommended for body heights up to 200 cm and has an overall sleeping bag length of 230 cm, a shoulder width of 85 cm and a foot width of 60 cm.<\/p>\n<p>If you are close to the upper end of a size range and prefer additional freedom of movement, you may want to consider the next size up. At the same time, the sleeping bag should not be unnecessarily large, as a greater internal volume means more air for your body to warm.<\/p>\n<p>Choosing the right size is therefore a balance between <strong>freedom of movement, enough room for the insulation to retain its loft and avoiding unnecessary internal volume.<\/strong><\/p>\n<p><strong>See Gr\u00fcezi Bag&#8217;s size chart in the product gallery for a visual overview of sleeping bag length, shoulder width and foot width for each size.<\/strong><\/p>\n<h3>Recycled materials and natural insulation<\/h3>\n<p>The outer and inner fabrics are made from <strong>100% recycled 20D 380T nylon<\/strong>. The material is lightweight and breathable while also being wind- and water-resistant.<\/p>\n<p>DownWool\u00ae 2.0 insulation consists of <strong>70% down and 30% wool<\/strong>. The 90\/10 down has a fill power of 700+ cuin, providing high insulation performance with low weight and excellent compressibility.<\/p>\n<p>Summer Light 2.0 is <strong>made in Germany<\/strong> and supplied with a compression stuff sack and storage bag.<\/p>\n<h3>Technical specifications<\/h3>\n<ul>\n<li><strong>Product:<\/strong> Gr\u00fcezi Bag DownWool Summer Light 2.0<\/li>\n<li><strong>Type:<\/strong> Lightweight summer sleeping bag<\/li>\n<li><strong>T Comfort:<\/strong> +7 \u00b0C<\/li>\n<li><strong>T Limit:<\/strong> +2 \u00b0C<\/li>\n<li><strong>T Extreme:<\/strong> \u221212 \u00b0C<\/li>\n<li><strong>Recommended temperature range:<\/strong> approx. +7 to +24 \u00b0C (Gr\u00fcezi Bag&#8217;s recommendation)<\/li>\n<li><strong>Insulation:<\/strong> DownWool\u00ae 2.0 \u2013 70% down \/ 30% wool<\/li>\n<li><strong>Down quality:<\/strong> 90\/10 down, 700+ cuin<\/li>\n<\/ul>\n<h4>Regular<\/h4>\n<ul>\n<li><strong>Recommended body height:<\/strong> up to 175 cm<\/li>\n<li><strong>Sleeping bag length:<\/strong> 200 cm<\/li>\n<li><strong>Shoulder width:<\/strong> 77 cm<\/li>\n<li><strong>Foot width:<\/strong> 50 cm<\/li>\n<li><strong>Weight:<\/strong> approx. 700 g<\/li>\n<li><strong>Pack volume:<\/strong> approx. 4 l<\/li>\n<\/ul>\n<h4>Long<\/h4>\n<ul>\n<li><strong>Recommended body height:<\/strong> up to 185 cm<\/li>\n<li><strong>Sleeping bag length:<\/strong> 215 cm<\/li>\n<li><strong>Shoulder width:<\/strong> 80 cm<\/li>\n<li><strong>Foot width:<\/strong> 50 cm<\/li>\n<li><strong>Weight:<\/strong> approx. 750 g<\/li>\n<li><strong>Pack volume:<\/strong> approx. 4 l<\/li>\n<\/ul>\n<h4>Extra Long<\/h4>\n<ul>\n<li><strong>Recommended body height:<\/strong> up to 200 cm<\/li>\n<li><strong>Sleeping bag length:<\/strong> 230 cm<\/li>\n<li><strong>Shoulder width:<\/strong> 85 cm<\/li>\n<li><strong>Foot width:<\/strong> 60 cm<\/li>\n<li><strong>Weight:<\/strong> approx. 850 g<\/li>\n<li><strong>Pack volume:<\/strong> approx. 4.3 l<\/li>\n<\/ul>\n<ul>\n<li><strong>Construction:<\/strong> Mummy shape<\/li>\n<li><strong>Hood:<\/strong> adjustable<\/li>\n<li><strong>Thermal collar:<\/strong> lightweight thermal collar<\/li>\n<li><strong>Zip:<\/strong> two-way Auto-Lock zip with anti-snag protection<\/li>\n<li><strong>Foot ventilation:<\/strong> yes<\/li>\n<li><strong>Footbox:<\/strong> pre-shaped<\/li>\n<li><strong>Pillow pocket:<\/strong> yes<\/li>\n<li><strong>Pockets:<\/strong> internal and external<\/li>\n<li><strong>Outer fabric:<\/strong> 100% recycled 20D 380T nylon<\/li>\n<li><strong>Inner fabric:<\/strong> 100% recycled 20D 380T nylon<\/li>\n<li><strong>Country of manufacture:<\/strong> Germany<\/li>\n<li><strong>Included:<\/strong> sleeping bag, compression stuff sack and storage bag<\/li>\n<\/ul>\n<h3>Variants<\/h3>\n<ul>\n<li><strong>Regular:<\/strong> SKU 5300-3020-175 \u00b7 EAN 4262522192335 \u00b7 Ocean Green<\/li>\n<li><strong>Long:<\/strong> SKU 5301-4017-185 \u00b7 EAN 4262522192342 \u00b7 Blue Ashes<\/li>\n<li><strong>Extra Long:<\/strong> SKU 5302-4017-200 \u00b7 EAN 4262522192359 \u00b7 Blue Ashes<\/li>\n<\/ul>\n<h3>Material composition<\/h3>\n<p>\n<strong>Outer fabric:<\/strong> 100% recycled nylon.<br \/>\n<strong>Inner fabric:<\/strong> 100% recycled nylon.<br \/>\n<strong>Fill:<\/strong> 70% down \/ 30% wool.<br \/>\n<strong>Down:<\/strong> 90\/10 down, 700+ cuin.<br \/>\nContains non-textile parts of animal origin.<\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"PDq2pG_selectionAnchorContainer\" data-start=\"663\" data-end=\"854\"><strong data-start=\"663\" data-end=\"751\">Lightweight and warm summer sleeping bag with award-winning DownWool\u00ae 2.0 insulation<\/strong>, combining the warmth and low weight of down with wool\u2019s ability to regulate temperature and moisture.<\/p>\n<p data-start=\"859\" data-end=\"1127\">Designed for <strong data-start=\"872\" data-end=\"955\">hiking, bikepacking, camping, travel and summer adventures in milder conditions<\/strong>.
